Unfortunately legalising drugs that can potentially have negative medical side effects (as opposed to harmless weed) is going to be difficult because far too many people think that things that are bad for you (when not dosage controlled, anyway) should be illegal.
Are people being slightly hyperbolic in their description of the Drug War? That's a genuine question, as I see dramatic screeds written throughout the internet.
I guess (hope) it will end with the legalisation of cannabis, ecstasy and psychedelics (hopefully enough to curtail the sale of "legal highs"); the providing of heroin in safe rooms across the country and the medical treatment of meth/crack users.
Dunno what to do about cocaine though.
Really, coke's the one you single out?
