Personally, I think it's better than coke, meth, etc. BUT that depends on who uses it. I have a girlfriend who pays her bills first, puts some cash in her savings account, than buys her pot. She only smokes on Fridays and Saturdays so it doesn't interfere with work. On the other side of the fence I have a guy friend who smokes all day, every day. He's 28 YO, works at a pizza joint delivering pizzas, and sells his weed. He doesn't make any money off selling it, though, because he only sells to friends and feels bad about charging them. He has no goals for his life and has no money. I think it just depends on if you let it control your life or use it as a pleasurable past time.
Although, I have to disagree with some of you. I wouldn't want a person who's high driving anymore than a person who's drunk. They aren't any better drivers, both impair your abilities and perceptions. I don't want to take any chances while my kids are in the car. You do hear about it but most people hear "driving under the influence" and automatically think alcohol.
I do agree that if they taxed it, it could bring some much need financial help.
BTW, if you look at medical data weed isn't any better for your body or brain in the long term than any other drug.
I guess I'm on the fence. There would definitely have to be some laws.
