You also have to understand, you're talking to a bunch of people who smoke weed. It's hard to convince us that weed's the problem when all of us here know it's not. At one time I think we all used to be like you, we believed the government at face value and accepted the fact that because it's illegal, it must be immoral, too. Then we all grew up a little bit and realized our own experiences should shape the path of our lives, not what someone else tells us to think. If you've never smoked weed, I'd suggest you give it a try, to at least see what all the fuss is about. When you realize it's no big deal, I think you'll realize that it's your boyfriend, not the weed, that has turned him the way he is.
