I would firstly like to correct you there Echo, antipsychotics can be and are prescribed for depression as well as SSRIs. There are various forms of depression which can cause thought disorder, delusional thinking, and hallucinations. I for instance get intermittent dissociation (look it up if you don't know what it is) which is quite a classic symptom of moderate to severe depression, something that can be treated with antipsychs.
That said I do not advocate their use unless absolutely necessary. Same goes for SSRIs which are WAY WAY too often prescribed when other forms of treatment are more suitable. These drugs are little understood especially in terms of how they affect you in the long term. Moreover, it is unclear whether they actually do make you more 'balanced' emotionally or if they simply cut one off from their own emotional baggage. Moreover, depression is misconceived as being only about mood by most of the population and doctors. Depression involves a fundamental difference in ideology and how we work with the world. It pervades almost every aspect of one's life, something that is quite hard to explain to those who do not suffer from it.
Finally, Rod was not, I think, advocating the use of opiates. He was extolling their apparent virtues in relation to himself. He made it quite clear that he was only talking about his experience with them. If anything he was only suggesting that you shouldn't decide what is bad for you based on a taboo, but instead decide that based on research, experience reports and your own experiences if you've tried it. He wasn't saying 'go out and try them', but 'if you are interested and trust your own judgement and care, then you shouldn't limit yourself because other people tell you to'. Correct me if I'm wrong there.
As an aside, I also generally don't enjoy weed. It makes my heart race, and I smoked it heavily for two years anyway like a bloody idiot! I do enjoy a nice hash spliff if I'm drunk or coming down though

mmmmmmm
