Marijuana does not cause people to act violently. The reason violence is so often associated with pot is not because of the drug itself, but rather because of the drug
trade in marijuana. The government’s current policy towards marijuana and all drugs “The War on Drugs” has made selling pot extremely profitable for the few cartels that are in the business. The reason this “zero tolerance” policy has made drugs profitable is because of a simple economic principle. When supply decreases, and demand remains the same, prices will rise.
