Lol Fox News... I don't believe it. To be honest, I don't trust any "research" done out there. It's always biased, either by a government who wants to make pot look as bad as possible, or smokers who want to make it look as harmless as possible. But really, when you smoke a joint, you smoke one joint between like 3 people and you can be good to go for like an hour. How many cigarette smokers can smoke 1/3 of a cigarette per hour?
