I'll take Cruise's bait and reply to his outburst...
he says it would be an ideal situation if people didn't need to take drugs, and I would agree.
But that's the problem with alot of ideals, is that they don't quite bridge the gap between their ideals and reality... that is, even though it would be optimal to get there, if there's no solution on how to get there, or accounting for all the unchangables or unpredictable stuff, then the ideal falls flat on its face. Even worse, it acts as a corruption of thought.
It's true that drugs only really serve as a band-aid solution to problems. Not even that; it's like he says, they mask the symptoms of the problem.
But the reality is that, there are no conclusive super effective solutions in place, that the symptoms are really what people want to avoid anyway (I mean... herpes only sucks when its expressed... for the good portion of people that have it and never express it, it doesn't matter to them (ignoring its transmissability)). And that without the bandaid, worse problems can and do occur to those individuals.
As for a solution, the problem is a social one in some sense; we've become such a drugged up culture, we also see the drugs as a solution to the problem... but it's not a real solution; we need to recognise the reality of its uses, that it can serve to stem some effects, but can also cause other effects (side effects); that a real solution needs to be found, through whatever cure people have found for the problem.
But in the cases of these mental disorders, given the variability of environmental stresses as well as chemical balances and genetics, it's almost always the case that what works for some people might not work for another.
Root causes and solutions need to be found for these problems... but in some cases, the solution won't be forthcoming for years or decades... and in the meantime, all you can really do is patch the problem with the drugs, lest the problem get out of hand and cause more problems.
Personally, I think alot of modern problems lie in the chemical imbalances of a modern diet, as well as the hectic, dissonating lifestyle and culture that we've created. Solving these two problems will solve many issues. But identifying the specifics beyond broad strokes is a little trickier said than done.
