The Great Pot Experiment
While American research on the potential harms from marijuana is booming, the U.S. continues to lag in funding investigations into the possible benefits. A study, done by the Institute of Medicine in response to California’s 1996 legalization of medical marijuana found that pot wasn’t a hippie’s delusion.
The research showed that the stuff held real therapeutic potential for specific conditions, including epilepsy, chronic pain and glaucoma. Yet, the U.S. doubled down on the war on drugs at the time.
There are now signs of change. This year, the Colorado department of public health awarded $9 million in grants for medical-marijuana research, funded with tax revenue from state-licensed pot stores. These will be among the first U.S. clinical trials to look into the effectiveness of marijuana.

“The ending of [weed] prohibition in Colorado has had a huge impact on my life,” he says. “I’ve been able to safely and effectively find cannabis treatments that improve my quality of life.”
