I'm concerned about not so much the medication but our focus on it...despite the economist's assessment that the drugs really have the greatest impact on our health or at least perception of it (supposing you took a "material worth" way of assessing it.) One of the most significant concerns is that the focus of pharmaceuticals is compartmentalisation- specific targeting and isolation of cause etc. To this end, there's a good reason for the rise for alternative therapies- they're generally more wholistic in approach, but the reason most doctors etc. and other scientifically grounded health professionals don't buy into it (yet) is because "it's not science" or rather, not so measurable nor falsifiable. I won't comment on whether it works or not, though, because then this response would be too long!
The way I see it, perceptions on drugs etc. are split- there are those who swear by it, and there are those who think that drugs are the devil (to exaggerate somewhat)...more specifically that it's all part of a giant economic conspiracy to suck us out of the dollar etc. IMO, as far as is measurable, on average the drugs work. The problems are that the dollar is king anyway (but not to the extent that the pharmaceutical world is a giant extortion machine...this is more an incidental happening, not intentional), and that doctors are becoming obselete. We're (doctors, rather) pretty much expected to be the drug givers and so doctors tend to be pawns of a bureaucracy as well as possibly being under pressure from the various pharmaceutical companies for this or that. I know the latter bit doesn't happen quite so much in Australia, but I don't know about the US. I can say that it would be a cause for concern if the drug was bogus, though.
