I can't speak for the drugs themselves, but these people are on these drugs because they already have issues.

I've known/know people who are on them. One person cannot come off, and when she tries it makes life so bad she goes back on them in heavier doses. It's like yo-yo dieting.

Many antidepressants can't be dished out to people who are already suicidal because it will enhance those feelings. With others it makes them agressive, but makes them feel better. My concern is that there's little way a doctor can tell the difference between someone who'll get smashed or out of hand on drugs and what's considered to be a normal person. We all have different alocohol limits, for example. It might take you just a couple of pints to get you to the same place I'd be in if I drank eight. It's the same with drugs of any nature.
