225. Matt Rossheim | Intoxicating "Hemp" Products

What is hemp? The congressional definition is anything less than 0.3% dry weight delta-9 THC. This presents a major loop hole, legalizing intoxicating products that are tested for the first time, not on lab rats, but on our children. Dr. Rossheim is an expert on these derived intoxicating cannabis products and shares his research.
