On this week's episode of Shaping Fire, podcast host Shango Los speaks with Dr. Sunil Aggarwal about the historical relationship between the cannabis plant and humans. The story starts some 30,000 years ago with the development of cannabinoids in the plant and extends around the entire planet as humans propagate Cannabis everywhere they go. Dr Aggarwal's riveting account will give you a more solid understanding of the role Cannabis has played in our history and further insight into the absurdity of its prohibition.
