It is important to note that antidepressant addiction will usually present differently to other drug addictions. Unlike, say, cocaine, antidepressants are designed to allow the taker to operate normally in everyday life. An addict may, therefore, be able to continue their normal life and appear entirely functional to others despite having formed a dependence. And while antidepressants can be prepared to take by snorting or injection, almost all addicts will continue to take them normally. This means it’s often quite hard for an outsider to detect an addiction to antidepressants.
