You are soooo wrong.
Here are some facts about the effects of THC:
First of all, THC causes paranoia. Paranoia= psychotic disorder characterized by delusions of persecution, irrational distrust, impairment, insanity, and homicidal tendency.
When ISIS and other terrorist groups go on a massacre or suicide bombing, they first get wasted on hashish to create the "mood".
In fact, the word "assassin" comes from Hassasin, smokers of hashish. They were the original cult of killers out of Persia who regularly used murder as their primary political tool against Arabs, Turks, and Christians.
