The black market is what causes violence. Prohibiting a substance is like giving dealers a buisness liscence. Why is it ok for people to drink alcohol which is widely known to cause violence, and kill people. But when it comes to something that creates a sense of pascifisim that's wrong. I'm not saying all drugs are ok. But Cannabis has some benefits for medical and spiritual use. Is it ok that a student that got arrested on a drug cause gets there aide taken away? If a person is given a felony for a drug charge that's gonna prevent them from finding work. Which causes a number of problems. And witha near a million arrests last yr for posession or marijuana alone, most being simple possesion, wouldn't that damage the economy? Unemployment, social issues, housing ect?
