    The Gut-Brain Axis with Dr. Rick Pescatore

    25/08/2026 | 52 mins.
    In this episode of the Bioactive Podcast, Dr. Riley
    Kirk sits down with Dr. Rick Pescatore, board-certified emergency
    physician, Editor-in-Chief of Emergency Medicine News, and founder of
    BellyMD, for a fascinating deep dive into the gut-brain connection and
    what it means for cannabis users and patients dealing with unexplained
    digestive symptoms.

    Dr. Pescatore explains how the gut and brain communicate
    through the vagus nerve, why the gut has been called the “second brain,”
    and how genetics, diet, gut bacteria, inflammation, and cannabis can all
    influence this complex system. The conversation also explores cannabinoid
    hyperemesis syndrome (CHS) and why understanding CHS requires looking
    beyond cannabis alone and considering the broader gut-brain system.

    We also get into GLP-1 medications and gut-brain medicine,
    nausea and vomiting, microbiome health, micronutrient deficiencies, vitamin B1
    (thiamine), magnesium, and whether personalized health data could help us
    better understand why someone feels unwell. Dr. Pescatore shares how emerging
    tools, including phenomic data, wearable technology, AI, and the Menome
    platform, could help patients identify patterns that traditional medicine may
    overlook.

    We also discuss cannabis and the gut microbiome, CHS,
    thiamine deficiency, antibiotics and gut health, personalized medicine, patient
    autonomy, and the future of gut-brain healthcare.

    In this episode, we explore:

    - What is the gut-brain axis and how does the gut
    communicate with the brain?

    - Why does the gut have such a major role in
    neurotransmitters and brain health?

    - What does the gut microbiome have to do with anxiety,
    depression, and other conditions?

    - What is cannabinoid hyperemesis syndrome (CHS), and how
    does it fit into gut-brain health?

    - Could underlying gut-brain dysfunction contribute to
    cannabis-related symptoms?

    - How do GLP-1 medications affect the gut-brain axis?

    - What role do vitamin B1, magnesium, and micronutrients
    play in gut-brain health?

    - Can microbiome testing and wearable data help personalize
    healthcare?

    - Could AI help patients better understand their own health?

    - What does the future of personalized gut-brain medicine
    look like?

    This is a conversation about cannabis, medicine, the
    microbiome, nutrition, neuroscience, personalized health, and the emerging
    science connecting them all.

    What went down at the Cannabis Rescheduling Hearing with Max Jackson

    07/08/2026 | 1h 4 mins.
    What actually happened inside the DEA’s cannabis rescheduling hearing? In this timely episode of the Bioactive Podcast, Dr. Riley Kirk sits down with Max Jackson, former commercial cannabis cultivator and founder of Cannabis Wise Guys, to unpack what he witnessed firsthand at the DEA hearing on moving cannabis from Schedule I to Schedule III.

    Max spent most of the hearing inside the room, taking handwritten notes because recording and livestreaming were not permitted. As someone who previously managed a commercial cultivation facility with approximately 13,000 flowering cannabis plants, he offers a unique perspective on the arguments being made about cannabis, medical use, public health, research, and the plant itself.

    Together, Riley and Max break down who opposed rescheduling, what the government and opposing parties argued, and some of the surprising claims and misconceptions that came up during the proceedings. They discuss the difference between whole-plant cannabis and isolated cannabinoids, the challenges of dosing and medical education, cannabis research limitations, adverse effects, and why the lack of cannabis research is itself connected to decades of Schedule I restrictions.

    The conversation also explores what rescheduling to Schedule III could actually mean, what happens next in the process, why the administrative judge does not make the final decision, and why the DEA ultimately holds that decision.

    Whether you're a cannabis consumer, home grower, medical professional, researcher, cultivator, cannabis business owner, or simply trying to understand the future of cannabis policy in the United States, this episode gives you an inside look at a hearing most people never had the opportunity to see.

    Should THC Be a Range Instead of One Number? with guest Ben Cleary

    30/07/2026 | 1h 3 mins.
    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.

    Stop the Seed Ban! with Jim Riddle

    10/07/2026 | 51 mins.
    Cannabis seed laws are changing, and the consequences could reshape home grow, hemp, cannabis breeding, and the future of plant genetics in the United States.

    In this episode of the Bioactive Podcast, Dr. Riley Kirk sits down with longtime organic farmer, seed breeder, and policy advocate Jim Riddle to explain the proposed federal seed ban, why cannabis seeds are being caught up in new legislation, and what it could mean for growers, breeders, researchers, and consumers.

    Drawing from over four decades of experience in organic agriculture and public policy, Jim breaks down how a single sentence in federal legislation could classify cannabis seeds based on the THC content of the parent plant rather than the seed itself. Together, Riley and Jim discuss why many believe this is both scientifically flawed and harmful to innovation, home cultivation, and the broader hemp industry.

    The conversation also explores cannabis genetics, landrace preservation, hemp seed regulation, organic farming, home grow rights, the importance of genetic diversity, and practical ways listeners can advocate for keeping seeds legal.

    If you care about cannabis science, cultivation, hemp policy, seed preservation, or the future of cannabis genetics, this is an episode you won't want to miss.

    A Deep Dive into Tissue Culture with Nathan Johnson

    27/06/2026 | 1h
    Cannabis tissue culture, plant genetics, micropropagation, and pathogen testing are transforming modern cultivation. In this episode of the Bioactive Podcast, Dr. Riley Kirk is joined by Dr. Nathan Johnson, President & CEO of Verne Bio, for a fascinating deep dive into one of the most powerful—and misunderstood—tools in cannabis cultivation.

    Together they explore how tissue culture is helping preserve elite cannabis genetics, eliminate plant pathogens, improve cultivation consistency, and solve some of the industry's biggest challenges. Drawing from Dr. Johnson's extensive background in molecular biology, microbiology, bioinformatics, and plant science, the conversation breaks down how tissue culture works, why it's becoming essential for commercial cultivation, and what growers should know before adopting it.

    The discussion also examines cannabis testing, microbial contamination, remediation methods, irradiation, and the science behind maintaining healthy plants without sacrificing quality. They unpack how beneficial microbes interact with cannabis, why current testing regulations remain controversial, and the differences between qPCR, culture-based testing, sequencing, and pathogen detection. The episode also explores THC testing variability, why cannabinoid percentages aren't always the best indicator of quality, and how cultivation practices influence the chemistry consumers ultimately experience.

    Whether you're a home grower, commercial cultivator, cannabis scientist, breeder, laboratory professional, or simply curious about the future of cannabis science, this episode is packed with practical insights and evidence-based discussion.
