Here's an interesting site, in fact, a very interesting one indeed on the subject of drug rehab. Rather than the usual moralising it's a resource centre, telling you about the various types of drug rehab available, support groups and so on. There's also a directory of drugs and of drug slang.
I have to admit that the one that amused me, interested me perhaps, was their description of "party drugs" like sextasy. It's a mixture of Ecstacy and Viagra. The latter will give a man a higher sexual appetite and the former also makes it virtually impossible for him to ejaculate.
Gives doing it all night a new meaning perhaps?
