Ah, cannabis. Research on cannabis is incredibly difficult to perform in the U.S. because of the severe restrictions placed by the federal government. The plant has a varied and controversial history. It was made illegal partly because the end of alcohol prohibition left a vast enforcement organization without work -- and partly by inciting racist ideology regarding cannabis users. Today, legalization is opposed by pharmaceutical companies and many in the alcohol industry. Cannabis has been shown as a harm reduction safe alternative or adjunct for pain control with no risk of overdose death due to cannabis. Dr. Diane Dickinson has been studying medical cannabis for many years. Join Corinne Frugoni for a conversation with Dr. Dickinson about this medicinal, controversial and ancient plant.
