I used to work with someone who was a responsible, successful business man who nobody suspected might use heroin until a substantial change in heroin prices left him in panic chasing money to pay for his addiction. Had the drastic price change at the time not happened, chances are nobody would have found out. In other words:
You see the ones that ends up fucking up for one reason or another. You don't see the ones that manage, so you don't know whether nobody manages to deal with it, or if lots of people do.
(the other aspect of this is that his personal ruin, while facilitated by a heroin addiction, was triggered by the legal regime surrounding heroin that made it impossible for him to get at a low, predictable price; I've gradually come to believe that outlawing most drugs is ethically indefensible)
