  • Cannabis and Real World Data with Dr. Miyabe Shields

    Cannabis and Real World Data with Dr. Miyabe Shields
    Oct 3 2026
    Dr. Riley Kirk welcomes Dr. Miyabe Shields for a deep dive into cannabis real-world data, cannabis consumption patterns, dosing, neurodivergent cannabis use, and the Endocannabinoid System (ECS). As co-founders of the Network of Applied Pharmacognosy (NAP), Riley and Miyabe discuss the newly accessible Real Data Project, including what large-scale consumer data can reveal about how people actually use cannabis in their everyday lives. They explore why terms like “heavy cannabis consumption” are difficult to define, how consumption can vary by dose and frequency, and what the data shows across different populations and consumption methods. They also discuss the importance of making real-world cannabis data accessible to consumers, researchers, patients, and healthcare professionals rather than keeping it behind academic paywalls or within highly controlled research settings. The conversation also covers cannabis and neurodivergence, cannabis and mental health, the challenges of interpreting cannabis research, product chemistry and consumer experiences, terpene levels, cannabis aging, and how chemical data can eventually be connected with the way individual consumers actually feel after using a product. Finally, Riley and Miyabe discuss their ECS-focused e-book, created to make information about the Endocannabinoid System more accessible to both new and experienced cannabis consumers, including practical information about dosing, lifestyle, sleep, exercise, diet, and understanding your own ECS.

  • Unlocking Plant Potential: The Science of Carbon and Natural Fertilizers with Nik Nikolayev

    Unlocking Plant Potential: The Science of Carbon and Natural Fertilizers with Nik Nikolayev
    Sep 18 2026
    What if carbon is one of the most overlooked inputs in plant nutrition? In this episode of the Bioactive Podcast, Dr. Riley Kirk sits down with Nik Nikolayev, CEO of Rooted Leaf Agritech, to explore the science of carbon-based fertilizers, plant nutrition, biostimulants, organic acids, and the chemistry behind plant growth, yield, and quality. Nik breaks down how plants use carbon beyond simply taking up CO₂ from the atmosphere, and why forms of carbon such as acetate and citrate may provide important substrates that can enter plant metabolism. The conversation explores how carbon interacts with NPK nutrition, photosynthesis, energy allocation, nutrient uptake, and secondary metabolism, including the pathways involved in producing cannabinoids, terpenes, flavonoids, and sulfur-containing compounds. They also dive into natural fertilizers and plant-based biostimulants, including kelp, hibiscus, moringa, anthocyanins, humic and fulvic acids, and other botanical inputs. Nik explains the idea behind using medicinal plants and their chemistry in agriculture, how organic acids can interact with minerals, and why the form of a nutrient may matter as much as the nutrient itself. The conversation also explores the carbon economy of cannabis, trichome metabolism, terpene diversity, rare cannabinoids, sulfur chemistry, nutrient stress, and the challenges of testing compounds that occur at extremely low concentrations. Throughout the episode, Nik emphasizes the importance of connecting theoretical chemistry with practical growing results while acknowledging where the science is still developing.

  • Cannabis and Driving with Dr. Denise Valenti

    Cannabis and Driving with Dr. Denise Valenti
    Sep 4 2026
    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.
