BIOACTIVE

Dr. Riley Kirk has Dr. Denise Valenti on the podcast to discuss cannabis and driving, cannabis impairment, THC testing, and the challenges of determining whether someone is actually too impaired to drive. They explore why THC levels in the body do not necessarily correspond to impairment and how cannabis can affect vision, peripheral vision, contrast sensitivity, eye movement, balance, and pupil response.

They also discuss the limitations of current roadside cannabis testing compared with alcohol testing, including the challenges of using blood THC levels, cognitive tests, and field sobriety tests to determine cannabis impairment. Dr. Valenti explains her work developing technology that could combine multiple sensory measurements to identify impairment more accurately.

The conversation also explores how dose, tolerance, consumption method, individual differences, medical conditions, and baseline function can influence impairment and why there is no universal rule for how long someone should wait before driving after consuming cannabis. They discuss Drug Recognition Experts, the need for stronger scientific validation and national standards, and the importance of developing impairment-testing technology that is accurate and free from racial bias.

Finally, they discuss cannabis and driving research, harm reduction, the challenges of funding cannabis impairment studies, and why controlled, dose-specific research is needed to better understand the relationship between cannabis, impairment, and road safety.

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 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.

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.

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.
