In this episode of the Bioactive Podcast, Dr. Riley Kirk sits down with cannabis research scientist Ben Cleary to unpack groundbreaking research published in Scientific Reports examining THC variability in cannabis flower and what it means for consumers, cultivators, laboratories, and regulators. If you've ever wondered why the same strain can feel different from batch to batch—or why chasing the highest THC percentage often leads to disappointment—this conversation explains the science behind it. Ben shares how his team's research demonstrates the natural variability of THC within a single cannabis plant and why reporting one THC percentage may not accurately represent what consumers actually purchase. Together, Riley and Ben discuss the future of cannabis labeling, range-based THC reporting, lab testing variability, terpene science, chemical diversity, and how better education can improve purchasing decisions and consumer trust. They also explore why aroma may be a better guide than THC percentage alone, how Canada's cannabis industry is beginning to implement THC ranges, the role of laboratory variation in cannabis testing, and what future cannabis packaging could look like as science continues to evolve. Whether you're a cannabis consumer, cultivator, scientist, budtender, regulator, or simply curious about how cannabis testing really works, this episode offers an evidence-based look at one of the industry's biggest conversations.
