Matt Crawford speaks with Dr. Peter Grinspoon about his book, Seeing Through the Smoke: A Cannabis Specialist Untangles the Truth About Marijuana. The information we have regarding Cannabis is skewed for a multitude of reasons. First and foremost, racism and how we have regulated this drug has played a huge role in shaping what society thinks they "know" about Cannabis. Dr. Grinspoon touches on the medical value and potential benefits of Cannabis, as well as why Doctors and patients don't have the correct data to truly understand its potential. This is a complex issue, and we all need to step back, drop our assumptions and think anew about this drug and its place in society. Seeing Through the Smoke is a good place to start that journey.
