PCP gets an unjustly bad rap. Most people would be quite surprised to find out it's quite similar to Ketamine, a drug that many don't hesitate to party with and has recently shown positive results for treating depression.

"PCP makes you feel invincible and violent" is an urban myth -- one that Ketamine somehow doesn't share, despite its great similarity to PCP.

Of all drugs, the one most strongly associated with violence is alcohol. Yet hundreds of millions if not billions of people think nothing of using it at parties, bars, at home with their family, in front of their kids, etc. -- often with disastrous results -- yet it's perfectly legal.
