They're dealing with neurotic (not being judgment, these are a powerful class of drugs) people. Like lines of code, (saying) less is more. "oh by the way, some people get how's hooked on them and it really sucks to get off them". then the patient doesn't take them and get the relief from the problem they saw the psychiatrist for. Any responsible psychiatrist is well aware of the problem and going to get their patient past their current crisis first, and then not give them a script for 18 months for the patient to build an addiction. Unfortunately, not all psychiatrists will do that.
