A personal anecdote. My extended family has a long history of substance abuse and addiction. Of course, historically the substance so abused has mostly been alcohol (and tobacco, but that is less harmful in this kind of sense), and I saw [both first-hand and second-hand] a lot of direct and indirect effects of it that were very harmful and destructive. But recently, with another family member, I also saw first-hand the effects of addiction to another drug, methamphetamine, with induced psychosis, and I would choose dealing with an alcohol addict over this a thousand times. At least an alcohol addict is unlikely to suddenly decide to murder you, or to jump out of window, or any such mad move, just because some demons tell them or they suddenly realize that you have been an alien or a reptilian all along, or any similar crazy thing [which is actually pretty horrific when you face it in a real life from a close person]. A drunk person is also much more easily defeated physically than somebody who is high on meth and has some psychotic episode. [Though I am aware that alcohol caused or catalyzed many violent attack and murders too, I am not trying to trivialize that.]
