MARIJUANA AS MEDICINE?: The Science Beyond the Controversy
There are many reasons for wanting to understand what science has so far revealed—and what remains unknown—about marijuana's medical potential. Can marijuana really help people with AIDS (acquired immune deficiency syndrome), cancer, glaucoma, multiple sclerosis, or any of several other conditions it is purported to relieve?

Researchers have also studied how marijuana use affects individuals and society as a whole.
