Hahaha if you're in middle school I definetly don't think you should be smoking pot.
Kids that start smoking younger, like a lot of people these day, don't tend to understand what smoking is really about. Smoking isn't supposed to fuck you up. It's supposed to enhance your feelings, and your life. I see all these preppy kids these days talking about smoking, and how messed up they were, and it makes me sad to think that this is what weed has become. Something to fuck you up. The hippies had it all right. It's a tool to make your life better, not to replace your life. These people are why weed is seen as bad, and people often overlook the good side of things because they see the bad side.
And the younger you are, the less likely to tend to think you'll get caught. Rap is the last thing you need right now. I'll have to agree with ian and say wait until you're older. And if your parents find out you smoke now, and they're tight, you're going to lose a lot of opportunities later because they'll be more up your ass. All in all, if you're gonna smoke, it doesn't matter what I say. Just be responsible, and enjoy it. For yourself.
