The reason cannabis is illegal in the US is because a bunch of police officers blamed all the crime in the area on "stoned negro men". That's it. Propaganda spread...and it eventually was made..illegal. There's your awnser. PROPAGANDA. I think the History channel did a story on it, too. I highly doubt anyone was made "emotionally unstable" because of it..most of these people already had an exsisting problem.
