There have been extensive studies and reaserch in marijuana recently, they have found that it does not cause any type of permanent damage to the brain, a 20 year study in Canada (atleast I believe it was in Canada) showed that it does not do any permanent damage to lungs. The only reported case of death from marijuana was because someone smoked it when there was poisoness mold on it. People don't go into blind rages or get cancer from it like alcohol or tobacco. There have been very few if any car crashes caused by someone driving while they were high. Why doesn't congress just figure out how to tax it and make it legal, the prison system will be much emptier, it will cause the drug cartel to lose money, it will drastically improve our economy. Nothing bad can come out of legalizing pot, so why don't they just do it. I don't understand.
