Methadone and Weed
Methadone and Weed
Most people who consume marijuana do so for its mood-altering and relaxing abilities. Weed gives people a high and allows them to relax. However, heavy consumption of weed can cause unwanted results. It can increase the anxiety and depression a person experiences, and it can interact with certain other drugs including Methadone. It is important to remember that interactions do occur with all types of drugs, to a great or lesser extent and this article details the interactions of mixing Methadone and Weed.
Mixing Methadone and Weed
Methadone, sold under the brand names Dolophine and Methadose among others, is a synthetic opioid agonist used for chronic pain and also for opioid use disorder. It is used to treat chronic pain, and it is also used to treat addiction to heroin or other opioids. Prescribed for daily use, the medicine relieves cravings and removes withdrawal symptoms. Withdrawal management using methadone can be accomplished in less than a month, or it may be done gradually over a longer period of time, or simply maintained for the rest of the patient’s life. While a single dose has a rapid effect, maximum effect can take up to five days of use. After long-term use, in people with normal liver function, effects last 8 to 36 hours. Methadone is usually taken by mouth and rarely by injection into a muscle or vein.
Side effects are similar to those of other opioids. These frequently include dizziness, sleepiness, vomiting, and sweating. Serious risks include opioid abuse and respiratory depression. Abnormal heart rhythms may also occur due to a prolonged QT interval. The number of deaths in the United States involving methadone poisoning declined from 4,418 in 2011 to 3,300 in 2015. Risks are greater with higher doses. Methadone is made by chemical synthesis and acts on opioid receptors.
Methadone was developed in Germany around 1937 to 1939 by Gustav Ehrhart and Max Bockmühl. It was approved for use as an analgesic in the United States in 1947, and has been used in the treatment of addiction since the 1960s. It is on the World Health Organization’s List of Essential Medicines.
Methadone is used for the treatment of opioid use disorder.
It may be used as maintenance therapy or in shorter periods to manage opioid withdrawal symptoms. Its use for the treatment of addiction is usually strictly regulated. In the US, outpatient treatment programs must be certified by the federal Substance Abuse and Mental Health Services Administration (SAMHSA) and registered by the Drug Enforcement Administration (DEA) in order to prescribe methadone for opioid addiction.
A 2009 Cochrane review found methadone was effective in retaining people in treatment and in the reduction or cessation of heroin use as measured by self-report and urine/hair analysis, and did not affect criminal activity or risk of death.
Treatment of opioid-dependent persons with methadone follows one of two routes: maintenance or withdrawal management. Methadone maintenance therapy (MMT) usually takes place in outpatient settings. It is usually prescribed as a single daily dose medication for those who wish to abstain from illicit opioid use. Treatment models for MMT differ. It is not uncommon for treatment recipients to be administered methadone in a specialized clinic, where they are observed for around 15–20 minutes post-dosing, to reduce the risk of diversion of medication.
The duration of methadone treatment programs ranges from a few months to years. Given opioid dependence is characteristically a chronic relapsing/remitting disorder, MMT may be lifelong. The length of time a person remains in treatment depends on a number of factors. While starting doses may be adjusted based on the amount of opioids reportedly used, most clinical guidelines suggest doses start low (e.g., at doses not exceeding 40 mg daily) and are incremented gradually. It has been found that doses of 40 mg per day were sufficient to help control the withdrawal symptoms but not enough to curb the cravings for the drug. Doses of 80 to 100 mg per day have shown higher rates of success in patients and less illicit heroin use during the maintenance therapy. However, higher doses do put a patient more at risk for overdose than a moderately low dose (e.g. 20 mg/day).
Methadone maintenance has been shown to reduce the transmission of bloodborne viruses associated with opioid injection, such as hepatitis B and C, and/or HIV. The principal goals of methadone maintenance are to relieve opioid cravings, suppress the abstinence syndrome, and block the euphoric effects associated with opioids.
Chronic methadone dosing will eventually lead to neuroadaptation, characterised by a syndrome of tolerance and withdrawal (dependence). However, when used correctly in treatment, maintenance therapy has been found to be medically safe, non-sedating, and can provide a slow recovery from opioid addiction. Methadone has been widely used for pregnant women addicted to opioids.
Methadone is used as an analgesic in chronic pain, often in rotation with other opioids. Due to its activity at the NMDA receptor, it may be more effective against neuropathic pain; for the same reason, tolerance to the analgesic effects may be less than that of other opioids.
Adverse effects of methadone include:
Methadone withdrawal symptoms are reported as being significantly more protracted than withdrawal from opioids with shorter half-lives.
When used for opioid maintenance therapy, Methadone is generally administered as an oral liquid. Methadone has been implicated in contributing to significant tooth decay. Methadone causes dry mouth, reducing the protective role of saliva in preventing decay. Other putative mechanisms of methadone-related tooth decay include craving for carbohydrates related to opioids, poor dental care, and general decrease in personal hygiene. These factors, combined with sedation, have been linked to the causation of extensive dental damage.
Methadone has the following US FDA black box warning:
Most people who overdose on methadone show some of the following symptoms:
The respiratory depression of an overdose can be treated with naloxone. Naloxone is preferred to the newer, longer-acting antagonist naltrexone. Despite methadone’s much longer duration of action compared to either heroin and other shorter-acting agonists and the need for repeat doses of the antagonist naloxone, it is still used for overdose therapy. As naltrexone has a longer half-life, it is more difficult to titrate. If too large a dose of the opioid antagonist is given to a dependent person, it will result in withdrawal symptoms (possibly severe). When using naloxone, the naloxone will be quickly eliminated and the withdrawal will be short-lived. Doses of naltrexone take longer to be eliminated from the person’s system. A common problem in treating methadone overdoses is that, given the short action of naloxone (versus the extremely longer-acting methadone), a dosage of naloxone given to a methadone-overdosed person will initially work to bring the person out of overdose, but once the naloxone wears off, if no further naloxone is administered, the person can go right back into overdose (based upon time and dosage of the methadone ingested).
As with other opioid medications, tolerance and dependence usually develop with repeated doses. There is some clinical evidence that tolerance to analgesia is less with methadone compared to other opioids; this may be due to its activity at the NMDA receptor. Tolerance to the different physiological effects of methadone varies; tolerance to analgesic properties may or may not develop quickly, but tolerance to euphoria usually develops rapidly, whereas tolerance to constipation, sedation, and respiratory depression develops slowly (if ever). Methadone fills the same opioid receptors in the brain as heroin and other prescription painkillers making it a suitable substitute.
Methadone treatment may impair driving ability. Drug abusers had significantly more involvement in serious crashes than non-abusers in a study by the University of Queensland. In the study of a group of 220 drug abusers, most of them poly-drug abusers, 17 were involved in crashes killing people, compared with a control group of other people randomly selected having no involvement in fatal crashes. However, there have been multiple studies verifying the ability of methadone maintenance patients to drive. In the UK, persons who are prescribed oral methadone can continue to drive after they have satisfactorily completed an independent medical examination which will include a urine screen for drugs. The license will be issued for 12 months at a time and even then, only following a favourable assessment from their own doctor. Individuals who are prescribed methadone for either IV or IM administration cannot drive in the UK, mainly due to the increased sedation effects that this route of use can cause.
In the United States, deaths linked to methadone more than quadrupled in the five-year period between 1999 and 2004. According to the U.S. National Center for Health Statistics, as well as a 2006 series in the Charleston Gazette (West Virginia), medical examiners listed methadone as contributing to 3,849 deaths in 2004. That number was up from 790 in 1999. Approximately 82 percent of those deaths were listed as accidental, and most deaths involved combinations of methadone with other drugs (especially benzodiazepines).
Although deaths from methadone are on the rise, methadone-associated deaths are not being caused primarily by methadone intended for methadone treatment programs, according to a panel of experts convened by the Substance Abuse and Mental Health Services Administration, which released a report titled “Methadone-Associated Mortality, Report of a National Assessment”. The consensus report concludes that “although the data remains incomplete, National Assessment meeting participants concurred that methadone tablets or Diskets® distributed through channels other than opioid treatment programs most likely are the central factors in methadone-associated mortality.”
In 2006, the U.S. Food and Drug Administration issued a caution about methadone, titled “Methadone Use for Pain Control May Result in Death.” The FDA also revised the drug’s package insert. The change deleted previous information about the usual adult dosage. The Charleston Gazette reported, “The old language about the ‘usual adult dose’ was potentially deadly, according to pain specialists.”
Methadone acts by binding to the µ-opioid receptor, but also has some affinity for the NMDA receptor, an ionotropic glutamate receptor. Methadone is metabolized by CYP3A4, CYP2B6, CYP2D6, and is a substrate, or in this case target, for the P-glycoprotein efflux protein, a protein which helps pump foreign substances out of cells, in the intestines and brain. The bioavailability and elimination half-life of methadone are subject to substantial interindividual variability. Its main route of administration is oral. Adverse effects include sedation, hypoventilation, constipation and miosis, in addition to tolerance, dependence and withdrawal difficulties. The withdrawal period can be much more prolonged than with other opioids, spanning anywhere from two weeks to several months.
The metabolic half-life of methadone differs from its duration of action. The metabolic half-life is 8 to 59 hours (approximately 24 hours for opioid-tolerant people, and 55 hours in opioid-naive people), as opposed to a half-life of 1 to 5 hours for morphine. The length of the half-life of methadone allows for exhibition of respiratory depressant effects for an extended duration of time in opioid-naive people.
Levomethadone (the L enantiomer) is a μ-opioid receptor agonist with higher intrinsic activity than morphine, but lower affinity. Dextromethadone (the S enantiomer) has lower affinity to the μ-opioid receptor than Levomethadone. Both enantiomers bind to the glutamatergic NMDA (N-methyl-D-aspartate) receptor, acting as noncompetitive antagonists. Methadone has been shown to reduce neuropathic pain in rat models, primarily through NMDA receptor antagonism. NMDA antagonists such as dextromethorphan, ketamine, tiletamine and ibogaine are being studied for their role in decreasing the development of tolerance to opioids and as possible for eliminating addiction/tolerance/withdrawal, possibly by disrupting memory circuitry. Acting as an NMDA antagonist may be one mechanism by which methadone decreases craving for opioids and tolerance, and has been proposed as a possible mechanism for its distinguished efficacy regarding the treatment of neuropathic pain. Methadone also acted as a potent, noncompetitive α3β4 neuronal nicotinic acetylcholine receptor antagonist in rat receptors, expressed in human embryonic kidney cell lines.
Methadone has a slow metabolism and very high fat solubility, making it longer lasting than morphine-based drugs. Methadone has a typical elimination half-life of 15 to 60 hours with a mean of around 22. However, metabolism rates vary greatly between individuals, up to a factor of 100, ranging from as few as 4 hours to as many as 130 hours, or even 190 hours. This variability is apparently due to genetic variability in the production of the associated cytochrome enzymes CYP3A4, CYP2B6 and CYP2D6. Many substances can also induce, inhibit or compete with these enzymes further affecting (sometimes dangerously) methadone half-life. A longer half-life frequently allows for administration only once a day in opioid withdrawal management and maintenance programs. People who metabolize methadone rapidly, on the other hand, may require twice daily dosing to obtain sufficient symptom alleviation while avoiding excessive peaks and troughs in their blood concentrations and associated effects. This can also allow lower total doses in some such people. The analgesic activity is shorter than the pharmacological half-life; dosing for pain control usually requires multiple doses per day normally dividing daily dosage for administration at 8 hour intervals.
The main metabolic pathway involves N-demethylation by CYP3A4 in the liver and intestine to give 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP). This inactive product, as well as the inactive 2-ethyl-5-methyl-3,3-
diphenyl-1-pyrroline (EMDP), produced by a second N-demethylation, are detectable in the urine of those taking methadone.
The most common route of administration at a methadone clinic is in a racemic oral solution, though in Germany, only the R enantiomer (the L optical isomer) has traditionally been used, as it is responsible for most of the desired opioid effects. The single-isomer form is becoming less common due to the higher production costs.
Methadone is available in traditional pill, sublingual tablet, and two different formulations designed for the person to drink. Drinkable forms include ready-to-dispense liquid (sold in the United States as Methadose), and Diskets (known on the street as “wafers” or “biscuits”) tablets which are dispersible in water for oral administration, used in a similar fashion to Alka-Seltzer. The liquid form is the most common as it allows for smaller dose changes. Methadone is almost as effective when administered orally as by injection. Oral medication is usually preferable because it offers safety, simplicity and represents a step away from injection-based drug abuse in those recovering from addiction. U.S. federal regulations require the oral form in addiction treatment programs. Injecting methadone pills can cause collapsed veins, bruising, swelling, and possibly other harmful effects. Methadone pills often contain talc that, when injected, produces a swarm of tiny solid particles in the blood, causing numerous minor blood clots. These particles cannot be filtered out before injection, and will accumulate in the body over time, especially in the lungs and eyes, producing various complications such as pulmonary hypertension, an irreversible and progressive disease. The formulation sold under the brand name Methadose (flavored liquid suspension for oral dosing, commonly used for maintenance purposes) should not be injected either.
Information leaflets included in packs of UK methadone tablets state that the tablets are for oral use only and that use by any other route can cause serious harm. In addition to this warning, additives have now been included in the tablet formulation to make the use of them by the IV route more difficult.
Methadone and its major metabolite, 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP), are often measured in urine as part of a drug abuse testing program, in plasma or serum to confirm a diagnosis of poisoning in hospitalized victims, or in whole blood to assist in a forensic investigation of a traffic or other criminal violation or a case of sudden death. Methadone usage history is considered in interpreting the results as a chronic user can develop tolerance to doses that would incapacitate an opioid-naïve individual. Chronic users often have high methadone and EDDP baseline values.
The protonated form of methadone takes on an extended conformation, while the free base is more compact. In particular, it was found that there is an interaction between the tertiary amine and the carbonyl carbon of the ketone function (R3N ••• >C=O) that limits the molecule’s conformation freedom, though the distance (291 pm by X-ray) is far too long to represent a true chemical bond. However, it does represent the initial trajectory of attack of an amine on a carbonyl group and was an important piece of experimental evidence for the proposal of the Bürgi–Dunitz angle for carbonyl addition reactions.
Methadone was developed in 1937 in Germany by scientists working for I.G. Farbenindustrie AG at the Farbwerke Hoechst who were looking for a synthetic opioid that could be created with readily available precursors, to solve Germany’s opium and morphine shortage problem. On 11 September 1941 Bockmühl and Ehrhart filed an application for a patent for a synthetic substance they called Hoechst 10820 or Polamidon (a name still in regular use in Germany) and whose structure had little relation to morphine or other “true opiates” such as diamorphine (Heroin), desomorphine (Permonid), nicomorphine (Vilan), codeine, dihydrocodeine, oxymorphone (Opana), hydromorphone (Dilaudid), oxycodone (OxyContin), hydrocodone (Dicodid), and other closely related opium alkaloid derivatives and analogues. It was brought to market in 1943 and was widely used by the German army during WWII as a substitute for morphine.
In the 1930s, pethidine (meperidine) went into production in Germany; however, production of methadone, then being developed under the designation Hoechst 10820, was not carried forward because of side effects discovered in the early research. After the war, all German patents, trade names and research records were requisitioned and expropriated by the Allies. The records on the research work of the I.G. Farbenkonzern at the Farbwerke Hoechst were confiscated by the U.S. Department of Commerce Intelligence, investigated by a Technical Industrial Committee of the U.S. Department of State and then brought to the US. The report published by the committee noted that while methadone itself was potentially addictive, it produced “considerably” less euphoria, sedation, and respiratory depression than morphine at equianalgesic doses and was thus interesting as a commercial drug. The same report also compared methadone to pethidine. German researchers reported that methadone was capable of producing strong morphine-like physical dependence, which is characterized by opioid withdrawal symptoms which are lesser in severity and intensity compared to morphine, but methadone was associated with a considerably prolonged or protracted withdrawal syndrome when compared to morphine. Morphine produced higher rates of self-administration and reinforcing behaviour in both human and animal subjects when compared to both methadone and pethidine. In comparison to equianalgesic doses of pethidine (Demerol), methadone was shown to produce less euphoria, but higher rates of constipation, and roughly equal levels of respiratory depression and sedation.
In the early 1950s, methadone (most times the racemic HCl salts mixture) was also investigated for use as an antitussive.
Isomethadone, noracymethadol, LAAM, and normethadone were first developed in Germany, United Kingdom, Belgium, Austria, Canada, and the United States in the thirty or so years after the 1937 discovery of pethidine, the first synthetic opioid used in medicine. These synthetic opioids have increased length and depth of satiating any opiate cravings and generate very strong analgesic effects due to their long metabolic half-life and strong receptor affinity at the mu-opioid receptor sites. Therefore, they impart much of the satiating and anti-addictive effects of methadone by means of suppressing drug cravings.
It was only in 1947 that the drug was given the generic name “methadone” by the Council on Pharmacy and Chemistry of the American Medical Association. Since the patent rights of the I.G. Farbenkonzern and Farbwerke Hoechst were no longer protected, each pharmaceutical company interested in the formula could buy the rights for the commercial production of methadone for just one dollar (MOLL 1990).
Methadone was introduced into the United States in 1947 by Eli Lilly and Company as an analgesic under the trade name Dolophine. An urban myth later arose that Nazi leader Adolf Hitler ordered the manufacture of methadone or that the brand name ‘Dolophine’ was named after him, probably based on the similarity of “doloph” with “Adolph”. (The pejorative term “adolphine” would appear in the early 1970s.) However, the name “Dolophine” was a contraction of “Dolo” from the Latin word dolor (pain), and finis, the Latin word for “end”. Therefore, Dolophine literally means “pain end”.
Methadone was studied as a treatment for opioid addiction at the Addiction Research Center of the Narcotics Farm in Lexington, Kentucky in the 1950s, and by Rockefeller University physicians Robert Dole and Marie Nyswander in the 1960s in New York City. By 1976, methadone clinics had opened in cities including Chicago, New York, and New Haven, with some 38,000 patients treated in New York City alone.
Brand names include Dolophine, Symoron, Amidone, Methadose, Physeptone, Metadon, Metadol, Metadol-D, Heptanon and Heptadon among others.
In the US, generic methadone tablets are inexpensive, with retail prices ranging from $0.25 to $2.50 per defined daily dose. Brand-name methadone tablets may cost much more.
Methadone maintenance clinics in the US may be covered by private insurances, Medicaid, or Medicare. Medicare covers methadone under the prescription drug benefit, Medicare Part D, when it is prescribed for pain, but not when it is used for opioid dependence treatment because it cannot be dispensed in a retail pharmacy for this purpose. In California methadone maintenance treatment is covered under the medical benefit. Patients’ eligibility for methadone maintenance treatment is most often contingent on them being enrolled in substance abuse counseling. People on methadone maintenance in the US either have to pay cash or if covered by insurance must complete a pre-determined number of hours per month in therapeutic groups or counseling. The United States Department of Veteran’s Affairs (VA) Alcohol and Drug Dependence Rehabilitation Program offers methadone services to eligible veterans enrolled in the VA health care system.
Methadone maintenance treatment (MMT) cost analyses often compare the cost of clinic visits versus the overall societal costs of illicit opioid use. A preliminary cost analysis conducted in 2016 by the US Department of Defense determined that methadone treatment, which includes psychosocial and support services, may cost an average of $126.00 per week or $6,552.00 per year. The average cost for one full year of methadone maintenance treatment is approximately $4,700 per patient, whereas one full year of imprisonment costs approximately $24,000 per person.
Methadone is a Schedule I controlled substance in Canada and Schedule II in the United States, with an ACSCN of 9250 and a 2014 annual aggregate manufacturing quota of 31,875 kilos for sale. Methadone intermediate is also controlled, under ACSCN 9226 also under Schedule II, with a quota of 38,875 kilos. In most countries of the world, methadone is similarly restricted. The salts of methadone in use are the hydrobromide (free base conversion ratio 0.793), hydrochloride (0.894), and HCl monohydrate (0.850). Methadone is also regulated internationally as a Schedule I controlled substance under the United Nations Single Convention on Narcotic Drugs of 1961.
In the United States, prescription of methadone requires intensive monitoring and must be obtained in-person from an Opioid Treatment Program—colloquially known as a ‘methadone clinic’—when prescribed for opioid use disorder (OUD). According to federal laws, methadone cannot be prescribed by a doctor and obtained from a pharmacy in order to treat addiction. Because of its long half-life, methadone is almost invariably prescribed to be taken in a single daily dose. At nearly all methadone clinics in the US, patients must visit a clinic to receive and take their dose under the supervision of a nurse. Both patients who are new to methadone treatment and high-risk patients—such as those who are using drugs and alcohol, including cannabis—must visit the clinic daily.
After 90 days to six months (depending on the clinic), if patients have met the clinic’s criteria, they are typically eligible for take-home doses of methadone. Therefore, they may be allowed to take anywhere from one to six days to visit the clinic once or twice weekly instead of every day. In accordance with DEA and SAMHSA regulations, patients who use other drugs may not be eligible for take-home methadone. Some clinics close on national holidays and provide doses to patients to take home.
In the 2000s, patients, doctors, nurses, those working in the addiction field, and advocates of many kinds have heavily criticized the extremely tight regulations regarding take-home methadone. Advocates for reforming methadone regulations argue that methadone could be much more effective if it was not necessary for patients to visit clinics daily. Many addicts seeking treatment usually avoid methadone or see it as a last resort, specifically because they do not want to have to go to a clinic every day to receive their medication.
The use of take-home doses was expanded during the first year of the COVID-19 pandemic.
In Russia, methadone treatment is illegal. In 2008, Chief Sanitary Inspector of Russia Gennadiy Onishchenko, claimed that Russian health officials are not convinced of the methadone’s efficacy in treating heroin and/or opioid addicts. Instead of replacement therapy and gradual reduction of illicit drug abuse, Russian doctors encourage immediate cessation and withdrawal. Addicts are generally given sedatives and non-opioid analgesics in order to cope with withdrawal symptoms. Brazilian footballer assistant Robson Oliveira was arrested in 2019 upon arriving in Russia with methadone tablets sold legally in other countries for what was considered drug trafficking under Russian law.
As of 2015 China had the largest methadone maintenance treatment program with over 250,000 people in over 650 clinics in 27 provinces.
In Australia and some other countries, methadone is available at pharmacies, not just at special clinics.
Research has found that anxiety is one of the leading symptoms created by marijuana in users, and that there is a correlation between Methadone and Weed and an increase in anxiety.
Anyone mixing Methadone and weed is likely to experience side effects. This happens with all medications whether weed or Methadone is mixed with them. Side effects can be harmful when mixing Methadone and weed. Doctors are likely to refuse a patient a Methadone prescription if the individual is a weed smoker or user. Of course, this could be due to the lack of studies and research completed on the mixing of Methadone and Weed.
Heavy, long-term weed use is harmful for people. It alters the brain’s functions and structure, and all pharmaceuticals and drugs including Methadone are designed to have an impact on the brain. There is a misplaced belief that pharmaceuticals and medication work by treating only the parts of the body affected yet this is obviously not the case in terms of Methadone. For example, simple painkiller medication does not heal the injury, it simply interrupts the brains functions to receive the pain cause by the injury. To say then that two drugs, Methadone and Weed, dol not interact is wrong. There will always be an interaction between Methadone and Weed in the brain11.J. D. Brown and A. G. Winterstein, Potential Adverse Drug Events and Drug–Drug Interactions with Medical and Consumer Cannabidiol (CBD) Use – PMC, PubMed Central (PMC).; Retrieved September 27, 2022, from https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6678684/.
One of the milder side effects of mixing Methadone and Weed is Scromiting. This condition, reportedly caused by mixing Methadone and Weed, describes a marijuana-induced condition where the user experiences episodes of violent vomiting, which are often so severe and painful that they cause the person to scream. The medical term for Scromiting by mixing Methadone and Weed is cannabinoid hyperemesis syndrome, or CHS. For these reasons, some people choose to quit smoking weed.
It was first included in scientific reports in 2004. Since then, researchers have determined that Scromiting is the result of ongoing, long-term use of marijuana—particularly when the drug contains high levels of THC, marijuana’s main psychoactive ingredient. Some experts believe that the receptors in the gut become overstimulated by THC, thus causing the repeated cycles of vomiting.
In the long run, a person can become even more depressed. There is a belief that marijuana is all-natural and not harmful to a person’s health. This is not true and Methadone and weed can cause health issues the more a person consumes it.
How does Weed effect the potency of Methadone?
The way in which the body absorbs and process Methadone may be affected by weed. Therefore, the potency of the Methadone may be less effective. Marijuana inhibits the metabolization of Methadone. Not having the right potency of Methadone means a person may either have a delay in the relief of their underlying symptoms.
A person seeking Methadone medication that uses weed should speak to their doctor. It is important the doctor knows about a patient’s weed use, so they can prescribe the right Methadone medication and strength. Or depending on level of interactions they may opt to prescribe a totally different medication. It is important for the doctor to know about their patient’s marijuana use. Weed is being legalized around the US, so doctors should be open to speaking about a patient’s use of it.
Sideffects of Methadone and Weed
Many individuals may not realize that there are side effects and consequences to mixing Methadone and Weed such as:
- Shortness of breath
- Respiratory Depression
- Cardiac Arrest
Interestingly, it is impossible to tell what effect mixing this substance with Weed will have on an individual due to their own unique genetic make up and tolerance. It is never advisable to mix Methadone and Weed due to the chances of mild, moderate and severe side effects. If you are having an adverse reaction from mixing Methadone and Weed it’s imperative that you head to your local emergency room. Even mixing a small amount of Methadone and Weed is not recommended.
Taking Methadone and Weed together
People who take Methadone and Weed together will experience the effects of both substances. Technically, the specific effects and reactions that occur due to frequent use of Methadone and weed depend on whether you consume more weed in relation to Methadone or more Methadone in relation to weed.
The use of significantly more weed and Methadone will lead to sedation and lethargy, as well as the synergistic effects resulting from a mixture of the two medications.
People who take both weed and Methadone may experience effects such as:
- reduced motor reflexes from Methadone and Weed
- dizziness from Weed and Methadone
- nausea and vomiting due to Methadone and Weed
Some people may also experience more euphoria, depression, irritability or all three. A combination of weed and Methadone leads to significantly more lethargy which can easily tip over into coma, respiratory depression seizures and death.
Mixing weed and Methadone
The primary effect of weed is influenced by an increase in the concentration of the inhibitory neurotransmitter GABA, which is found in the spinal cord and brain stem, and by a reduction in its effect on neuronal transmitters. When weed is combined with Methadone this primary effect is exaggerated, increasing the strain on the body with unpredictable results.
Weed and Methadone affects dopamine levels in the brain, causing the body both mental and physical distress. Larger amounts of Methadone and weed have a greater adverse effect yet leading medical recommendation is that smaller does of Methadone can be just as harmful and there is no way of knowing exactly how Methadone and weed is going to affect an individual before they take it.
Taking Methadone and weed together
People who take Methadone and weed together will experience the effects of both substances. The use of significantly more Methadone with weed will lead to sedation and lethargy, as well as the synergistic effects resulting from a mixture of the two medications.
People who take both weed and Methadone may experience effects such as:
- reduced motor reflexes from Methadone and weed
- dizziness from weed and Methadone
- nausea and vomiting of the Methadone
Some people may also experience more euphoria, depression, irritability or all three. A combination of weed and Methadone leads to significantly more lethargy which can easily tip over into coma, respiratory depression seizures and death.
Weed Vs Methadone
Taking Methadone in sufficient quantities increases the risk of a heart failure. Additionally, people under the influence of Methadone and weed may have difficulty forming new memories. With weed vs Methadone in an individual’s system they become confused and do not understand their environment. Due to the synergistic properties of Methadone when mixed with weed it can lead to confusion, anxiety, depression and other mental disorders. Chronic use of Methadone and weed can lead to permanent changes in the brain22.G. Lafaye, L. Karila, L. Blecha and A. Benyamina, Cannabis, cannabinoids, and health – PMC, PubMed Central (PMC).; Retrieved September 27, 2022, from https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5741114/.
Methadone Vs Weed
Studies investigating the effects of drugs such as Methadone and weed have shown that the potential for parasomnia (performing tasks in sleep) is dramatically increased when Methadone and weed are combined. Severe and dangerous side effects can occur when medications are mixed in the system, and sleep disorders are a common side effect of taking weed and Methadone together.
When a small to medium amount of weed is combined with Methadone, sleep disorders such as sleep apnea can occur. According to the latest data from the US Centers for Disease Control and Prevention (CDC) most ER visits and hospitalizations caused by too much weed were associated with other substances such as Methadone.
How long after taking Methadone can I smoke weed or take edibles?
To avoid any residual toxicity it is advisable to wait until the Methadone has totally cleared your system before taking weed, even in small quantities.
Overdose on Methadone and weed
In the case of Overdose on Methadone or if you are worried after mixing Methadone and weed, call a first responder or proceed to the nearest Emergency Room immediately.
If you are worried about someone who has taken too much Methadone or mixed weed with Methadone then call a first responder or take them to get immediate medical help. The best place for you or someone you care about in the case of a medical emergency is under medical supervision. Be sure to tell the medical team that there is a mix of Methadone and weed in their system.
Mixing Methadone and weed and antidepressants
Weed users feeling depressed and anxious may be prescribed antidepressant medication. There are some antidepressant users who also use Methadone and weed. These individuals may not realize that there are side effects and consequences to consuming both Methadone, marijuana and a range of antidepressants.
Studies on weed, Methadone and antidepressants is almost nil. The reason for so little information on the side effects of the two is mostly down to marijuana being illegal in most places – although a number of states in the United States have legalized the drug.
Self-medicating with Weed and Methadone
A lot of people suffer from depression caused by weed and Methadone. How many? According to Anxiety and Depression Association of America (ADAA), in any given year, it is estimated that nearly 16 million adults experience depression. Unfortunately, that number is likely to be wrong due to under reporting. Many people do not report suffering from depression because they do not want to be looked at as suffering from a mental illness. The stigmas around mental health continue and people do not want to be labeled as depressed.
Potential side effects from mixing Methadone and weed
Quitting weed to take Methadone
Medical professionals say an individual prescribed or taking Methadone should not stop using weed cold turkey. Withdrawal symptoms can be significant. Heavy pot users should especially avoid going cold turkey. The side effects of withdrawal from weed include anxiety, irritability, loss of sleep, change of appetite, and depression by quitting weed cold turkey and starting to take Methadone.
A person beginning to use Methadone should cut back on weed slowly. While reducing the amount of weed use, combine it with mindfulness techniques and/or yoga. Experts stress that non-medication can greatly improve a person’s mood.
Weed and Methadone can affect a person in various ways. Different types of marijuana produce different side effects. Side effects of weed and Methadone may include:
- loss of motor skills
- poor or lack of coordination
- lowered blood pressure
- short-term memory loss
- increased heart rate
- increased blood pressure
- increased energy
- increased motivation
Mixing Methadone and weed can also produce hallucinations in users. This makes marijuana a hallucinogenic for some users. Weed creates different side effects in different people, making it a very potent drug. Now, mixing Methadone or other mental health drugs with weed can cause even more unwanted side effects.
Mixing drugs and weed conclusion
Long-term weed use can make depression and anxiety worse. In addition, using marijuana can prevent Methadone from working to their full potential33.J. D. Brown and A. G. Winterstein, Potential Adverse Drug Events and Drug–Drug Interactions with Medical and Consumer Cannabidiol (CBD) Use – PMC, PubMed Central (PMC).; Retrieved September 27, 2022, from https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6678684/. Weed consumption should be reduced gradually to get the most out of prescription medication. Marijuana is a drug and it is harmful to individual’s long-term health. Weed has many side effects and the consequences are different to each person who uses it, especially when mixed with Methadone.
