I mean, I've never done drugs myself so I can't speak on behalf of first hand knowledge, but I will say that I don't think there is much benefit in making them illegal. The demand for drugs is extremely inelastic as these things are very addictive, and this placing legal measures only forces drug addicts to use more desperate measures to get their stuff. I also think it is a but foolish to arrest people and throw them in prison for non-violent drug offenses.
