Speaking at a Cato forum Tuesday, Dr. Donald Abrams, director of Clinical Programs at the University of California Osher Center for Integrative Medicine, discussed the science behind medicinal marijuana, and explained why the drug should be allowed for patients who suffer from a variety of symptoms.

After the event, Abrams spoke with Caleb Brown for Wednesday’s Cato Daily Podcast, explaining the promise of marijuana as medicine:

One of the reasons I am in favor of people using the plant is because… we no longer have a health care system in the United States, we have a disease management system, and it is very expensive largely due to pharmaceuticals. If there is a plant that is a medicine that people can grow for themselves in their own backyard then I think we can really go a long way to decrease some of the costs of health care. But if we are saying that a physician is going to be able to prescribe this entity to a patient then unfortunately, or fortunately depending on how you look at it, it does need to be regulated or approved and the only way to do that is through the standard route.
