    Researching and Growing Cannabis with Dr. Emily Gogol

    17/04/2026 | 1h 21 mins.
    On this episode, Dr. Riley Kirk welcomes Dr. Emily Gogol to the Bioactive Podcast to discuss the science, cultivation, and accessibility of cannabis from both a research and real-world growing perspective. Drawing from her background in biomedical science and her work leading Infinite Tree and Grow It From Home, Emily shares her journey from infectious disease research into cannabis farming, and how she applies data-driven methods to breeding, field trials, and terpene selection. They explore the process of developing stable, uniform cannabis genetics, the role of sensory evaluation (“the nose”) in selecting cultivars, and the importance of simplifying cannabis cultivation for home growers.

    The conversation also dives into practical growing techniques, including seed starting, drying and curing methods, and how to assess plant health and readiness. They discuss common challenges growers face, from germination myths and hermaphrodite stress to the differences between indoor and outdoor genetics. Additionally, they explore the evolving landscape of cannabis access, including home growing, seed distribution, and the impact of hemp regulations on small businesses and patients. The dialogue further highlights DIY approaches to cannabis as medicine, cannabinoid differences such as CBD, THC, and CBG, and the importance of education in empowering growers. Finally, they touch on the broader vision of making cannabis cultivation more approachable, sustainable, and accessible to communities nationwide.

    This is a conversation for anyone who wants to better understand the science behind cannabis cultivation, explore practical growing techniques, and gain the confidence to approach cannabis as both a plant and a tool for self-sufficiency.

    New Research on Cannabinoid Hyperemesis Syndrome (CHS) with Dr. Codi Peterson and Megan Mbengue

    04/04/2026 | 55 mins.
    On this episode of the Bioactive Podcast, Dr. Riley Kirk is joined by Dr. Codi Peterson and Megan Mbengue to discuss their newly published paper on Cannabinoid Hyperemesis Syndrome (CHS). Drawing from their recently published research and clinical experience, they explore what CHS is, how it presents, and why it is often misunderstood or misdiagnosed. The conversation covers early warning signs, the prodromal phase, and the severe symptoms patients experience, including the challenges faced in emergency care settings. They also address common misconceptions around cannabis use patterns, frequency, and the role of THC in the development of CHS.

    They discuss key factors influencing CHS, including consumption methods such as vaping versus flower, rapid THC absorption, tolerance, and the impact of high-potency products. The discussion explores myths around pesticides, synthetic cannabinoids, and the importance of distinguishing correlation from causation in cannabis-related health outcomes. Additionally, they examine strategies for reducing risk, including tolerance breaks, balanced use, and patient education without stigma. The dialogue further highlights the importance of compassionate care, proper diagnosis, and the role of healthcare professionals in bridging the gap between cannabis use and medical understanding. Finally, they touch on future research directions, the importance of data collection, and how education can shape safer, more informed cannabis use.

    This is a conversation for anyone using cannabis regularly, healthcare professionals seeking to better understand CHS, or patients navigating unexplained symptoms. Whether you're exploring cannabis for wellness or working in clinical settings, this episode provides critical insight into responsible use, early warning signs, and the evolving science behind cannabis-related health outcomes.

    06/03/2026 | 1h 10 mins.
    There are all sorts of misconceptions about coffee — that it dehydrates you, that it’s bad for your heart, or that caffeine is the only thing happening in the cup.

    Dr. Riley Kirk welcomes coffee scientist Dr. Steven Helschien, widely known as “Dr. Coffee,” for a fascinating conversation exploring the chemistry, health effects, and cultural significance of one of the world’s most widely consumed psychoactive plants: coffee. With a background in chemistry and extensive experience in coffee education and research, Dr. Helschien breaks down the complex science behind coffee in a way that is both practical and accessible.

    They discuss coffee as a psychoactive plant medicine, examining not only caffeine but also the wide range of entourage compounds that influence its physiological and cognitive effects.

    Dr. Helschien and Dr. Kirk explore coffee’s relationship with inflammation, liver health, and cardiovascular markers, unpacking what current research suggests about coffee consumption and long-term wellness. They also explore the importance of coffee quality, including concerns about mold contamination, sourcing practices, and what consumers should look for when choosing high-quality beans. The conversation touches on brewing techniques and the science of extraction, the chemistry behind decaffeination methods, and why caffeine affects the body the way it does.
    The episode also expands into broader discussions about coffee as plant medicine, the cultural role of caffeine, and the fine line between daily ritual and dependence.
    Dr. Helschien shares insights into mold-free coffee sourcing, considerations around caffeine and breastfeeding, and practical strategies like caffeine cycling to maintain sensitivity to its effects.

    This is a conversation for anyone who loves coffee but wants to understand what’s really happening in the cup. Whether you're curious about caffeine’s effects, confused by common coffee myths, exploring brewing methods, or simply trying to get more out of your daily ritual, this episode offers science-backed insight in an accessible way.

    How Fast-Acting Products Actually Work with Harold Han, PhD

    20/02/2026 | 57 mins.
    Dr. Riley Kirk welcomes Dr. Harold Han, Chief Science Officer and Co-Founder of Vertosa to explore the fascinating world of the science powering modern cannabis beverages and infused products. Known in
    the industry as “The Happy Chemist,” Dr. Han explains how emulsion technology solves the classic oil-and-water problem that makes cannabinoids difficult to incorporate into drinks. The conversation breaks down how water-compatible cannabinoids are created, why droplet size and consistency matter for potency and onset, and how stability challenges differ between beverages and gummies.

    They explore oxidation rates of major cannabinoids, packaging risks like
    “scalping” from can liners, and new patented approaches to preserving potencyin infused drinks.

    They also examine the full beverage development pipeline, from cannabinoids and infusion technology to formulation, manufacturing,
    testing, and distribution, highlighting the many points where potency and
    quality can be affected. Dr. Han clarifies the difference between nano and
    micro emulsions, why most commercial cannabis drinks use nano systems, and how natural emulsifiers influence formulation choices. The discussion further explores how the human body processes emulsified cannabinoids, why food (especially fat) changes edible effects, and how fast-acting beverages work at a physiological level. They discuss new human research initiatives, patient applications such as consistent dosing without sugar or smoke, and how standardized emulsions could transform both clinical research and at-home use.

    Looking ahead, Dr. Han shares insights on full-plant formulations, the future of cannabis as a precise delivery system for medicine, and the role of science-driven innovation in making cannabinoids more accessible, consistent, and scalable across recreational, wellness, and medical markets.
