I understand what you're saying and you're right that I don't think it is bad. Of course when I say things like that I take into account that you are old enough to understand moderation and responsibility. If someone is doing this (pretending that it was an intense high) so much that it affected their lives, then of course it should be regulated. There can always be too much of a good thing. However, the basic act isn't a problem.
Murder isn't a good example because it negatively affects someone else: the one murdered, obviously. Soft-core drugs, alcohol included, don't negatively affect anyone in terms of the effects (not taking into account what that person does that might harm someone while under the influence. That is a different topic.). When I say that nothing is wrong with it, I mean legally. I believe rehab is the correct place to send someone IF they have problems, not jail.
Hopefully I'm not delving too deep here heh.
