**** everything you just heard above.
First, marijuana does not fry your brain, or kill brain cells. In fact, it does the opposite, many studies have found that it promotes brain cell GROWTH.
Second, marijuana is less toxic than many drugs that physicians prescribe. No one has ever overdosed on marijuana, and no one has ever died from marijuana. This is amazing when compared to the immense amount of deaths caused by legal drugs today.
Third, it's completely natural. It is a plant, made by God himself. To say that we should condemn people for growing a plant, is saying we should condemn God for making it.
Fourth, marijuana is the best drug known to man. It can help with a lot of problems, and is completely safe as long as you do not do it in excess.
But please regard this as anything else, you wouldn't eat a piece of cake everyday would you? This would make you fat. So don't smoke marijuana everyday and should be fine, moderation is key. It's okay to smoke once or maybe even twice a week, but don't let it get out of control. You do the drugs, they don't do you.
