I'm readily agree that his could (or even is) an individual/specific case; but I am 100% certain that his decline was purely due to the drug (I lived with him during the whole period and we were extremely close). It was mostly intended as a rebuttal of: Anecdotally it has little or no effect on the ability of a person to "function." further up the thread. It seems that a decision has already been made: prohibition. I think there is dialogue to be had. I suspect (talking realistically) I will see legalization of a number of drugs in my lifetime.
