You are trying to make a moral judgement about drugs, but that's not the issue here. Demand/Supply don't care about the morality of the goods/services being traded. If there is demand for something, there will always be someone out there willing to provide what is demanded. There is nothing in this world that is 100% bad or 100% good. And as kyriacos said, many times our perception of bad/good is affected by other factors (eg media) and not by objective information. I think, for example, that it's quite likely that recreational drugs will become a normal thing in our lives in the future. Maybe not exactly the ones we have today, but as demand for them will increase, better ones will be made.
