hallucinogens
In general, kids should not use any drug that has not been prescribed to them by a doctor; there are many that would be hideously dangerous, but perhaps the most dangerous would be crystal meth. Crack cocaine is also extremely dangerous either to kids or to adults. Nicotine might be the most dangerous drug in the sense that kids are much more likely to wind up smoking cigarettes, which will eventually do great harm to their health, than they are to take up hard drugs such as cocaine.
PCP. Also known as Angel Dust; quite possibly the most dangerous hallucinogen
I have studied drugs for a very long time, and it is my opinion that Meth is the most dangerous drug in America. It is dangerous to take, and making it has turned more than one house into a Superfund site. Terrible stuff. Crack is second to meth in dangerousness. Third is probably heroin.
