The documentary is worth looking at tho. Not saying there are NO negative effect from marijuana, but what i am saying is most of the BS is false. This documentary while show you that it is not as bad as they make it seem, and in fact, it has a lot of health benefits. For all the people who like to compare cigarettes to weed will get doctors stating facts from research on the effect on both on the body, and you will be surprised to find out the effect on marijuana.
