I've never used any sort of drugs. I've never smoked or drank for that matter. The reason for this is simple, as a child growing up I always saw two sides, people telling me to stay away, and people encouraging me to do it. Neither side could ever give me a valid reason, so I just ignored everything. People would say generic things like "it's bad for you" and refuse to explain why, similarly they would say it's good and fail to explain how.
