> If, for example, you don't abuse but just use psychoactive drugs in some way, regularly, why? Especially if you like your job or things seem pretty good in your life.

Given your history I can certainly understand why you frame the issue this way, but I'll point out that this reads to me very much like "Why would you ever ride a rollercoaster, or go on vacation, or watch a movie, if you already like your job? Isn't life good enough?"

Because it's fun, or a change of pace, or just as a break. It really can be just that simple; it doesn't have to be a bulwark against depression or the result of peer pressure or isolation or failure to keep up or Our Modern Dysfunctional Lifestyle or etc.

I'm sorry, but based on this and many of your other followup questions and comments throughout this page it'd be easy to think that you've already decided on your conclusions and are hunting for evidence to support them.
