Why is marijuana illigael?

Weed is illegal because the government of the US is greedy. Hemp makes great paper and wood, and would thus put paper and lumber companies out of business. Hemp also makes good shampoo and clothing, thus putting more companies out of business. It is all about money. The government of the US makes money by putting people in jail and taking their money for pot. In Canada personal use and possession IS legal, and in Mexico as well; however; in Mexico you will be taken to jail for possesssion of more than five grams of Marijuana.
