I will say no. While it is possible that fairly common recreational drugs like alcohol, nicotine and caffeine also cause brain damage or induce psychopathy I don't think there is a particularly strong case that they do given the vast numbers of people taking them
That isn't an argument. Alcohol does negatively effect the brain in many instances, particularly in long term use. Long term use of alcohol is considerably more serious and lasting in it's consequences resulting in depression, anxiety, learning and memory problems, and
disruption of normal brain development. Many people usually do not develop a clear political ideology until their late 20s/early 30s. It is around this point that the long term effects of alcohol can be witnessed. Alcohol, for all intents and purposes, should be included in your poll as a recreational drug if you want any objective results in your "experiment".
