Smoking weed produces negative side effects?

I smoked weed for about 6 years on the regular. I have experienced about every negative side effect there is. weed is a psychoactive drug, it can have any number of effects on your brain. It differs from person to person. I dont smoke anymore, but even if i did, i would never know how i would react or feel afterwards. And all of my friends who still smoke still get those negative effects from time to time. Do i think that the way you react on weed is determined by a problem or a chemical imbalance? No. It is just a very powerful drug.
