Umm, it's one thing to have an existing substance problem to help soften life's blows; it's another to sit down and think to one's self. "Gosh, I'm facing so many problems. I should start taking substance X to deal with them!"

Especially considering the extent to which (so-called) anti-depressants and anti-anxiety drugs are being recognized for what they always have been -- a pseudo-scientific, market-driven fad (for the vast majority of cases which the companies making them have touted them as being useful for).

In any case he almost certainly doesn't need to go on pills -- and by definition, if he doesn't need them (and very, very few people do) he shouldn't start experimenting with them.
