Shared with the generous permission of Understanding CBD. This episode originally aired on Jun 13, 2023.
On this episode of Understanding CBD, host Steven Walman sits down with Dr. Amanda Reiman, a pioneering Cannabis ethnobotanist, social worker, and founder of Personal Plants. Together, they dive into the concept of harm reduction and how Cannabis plays a powerful role as both a substitute for more harmful substances and a supportive tool for chronic conditions. Dr. Reiman draws on over 20 years of research and advocacy to reframe Cannabis not as a “gateway drug” but as an off-ramp toward healthier choices and improved quality of life.
Key Takeaways
🛟 Harm reduction saves lives — it’s not about permission, it’s about meeting people where they are and keeping them safer.
🌿 Cannabis as a substitute — many use it as a healthier alternative to alcohol, nicotine, and even to ease withdrawal from more harmful drugs.
🚫🍭 The gateway myth is busted — research shows Cannabis doesn’t lead to harder drug use; sugar is the real “gateway drug.”
🧩 The ECS is central to health — the Endocannabinoid System regulates mood, sleep, appetite, and pain, and cannabinoid therapies help support it.
🔄 Tolerance is natural — but it can be managed with breaks, dose adjustments, or shifting cannabinoid profiles.
🧘♀️ Set and setting matter — your mindset and environment play a huge role in whether Cannabis feels supportive or overwhelming.
⚖️ Safe ≠ harmless — overconsumption can trigger anxiety or negative experiences, so mindfulness and dosing matter.
⏳ Think long-term — building a balanced relationship with Cannabis now ensures it will remain effective well into later life.
🩺 Healthcare providers must get involved — even without prescribing, they can guide patients in safe, responsible use and ECS education.
🛠️ Cannabis is a tool, not a crutch — when used with intention, it supports healthier choices and a better quality of life.
A note from the Editors: In this conversation, the term “psychoactive” is used in a way that may cause some confusion. To be precise, “psychoactive” describes any substance that affects the mind, mood, or behavior—including non-intoxicating agents such as caffeine or CBD. However, “intoxicating” refers specifically to effects that alter perception or cause impairment. While all intoxicating substances are psychoactive, not all psychoactive substances are intoxicating. For clarity and precision, readers are encouraged to consider the context in which these terms are used.
