Prescription drugs kill about 100,000 people in the world each year. Off the top of your head, do you know how many deaths are caused by using marijuana, either medicinally or recreationally? There are no deaths from cannabis use. Anywhere. You can't find one, said Dr. Lester Grinspoon, professor emeritus at Harvard Medical School. In 10,000 years of known use of cannabis, there's never been a single death attributed to marijuana. I've heard you have to smoke something like 15,000 joints in 20 minutes to get a toxic amount of delta-9 tetrahydrocannibinol, said Dr. Paul Hornby, a biochemist and human pathologist who also happens to be one of the leading authorities on cannabis research. - International Business Times
