You know I was reading this article in the paper and they were trying to come with points on why mj is actually bad for you, but they kept saying that if you're an occasional smoker than none of these symptoms won't really occur. And they kept mentioning if you are a heavy user (like 10 grams a day~~~no joke!) you would probably see some of the symptoms that longtime cig smokers have. So ummm... if you don't smoke 10 grms than you're OK! I have a friend who used to smoke pot in high school and now after a few years is all like: "don't smoke pot its bad for you!!" and she is trying to get her bf to stop smoking! But I don't care cuz I just throw it back in her face.
