About
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.
