According to U.S. researchers, marijuana has no negative effects on human health. They that determined that the weed users they studied were no more likely to go see the doctor than non-drug consumers.

Researchers from the Boston Medical Center and the Boston University School of Medicine randomly sampled patients who tested positive for marijuana to see if the marijuana-use had any impact on their health. They found that there's no difference between people who smoke cannabis daily and those who do not.

Should this study come as a surprise, or are people finally beginning to come around on weed?
