Free Refills: A Doctor Confronts His Addiction
Dr. Peter Grinspoon seemed to be a total success: a Harvard-educated M.D. with a thriving practice; married with two great kids and a gorgeous wife; a pillar of his community. But lurking beneath the thin veneer of having it all was an addict fueled on a daily boatload of prescription meds. When the police finally came calling – after a tip from a sharp-eyed pharmacist – Grinspoon’s house of cards came tumbling down fast.

Seeing Through the Smoke: A Cannabis Specialist Untangles the Truth about Marijuana
Depending on which doctor you speak with, or which websites you read, cannabis could be an appealing, low-risk medicine – even an aid to wellness – or an insidiously addictive drug rotting the brains of our youth. Seeing Through the Smoke is an unflinching examination at the grossly misunderstood drug that uses data-driven medical science and a critical historical perspective to reveal the truth behind cannabis.
Cannabis & Addiction Coaching
I am a certified physician health and wellness coach at Harvard Medical School who has personal experience with recovery from addiction. I have also been a leading medical cannabis specialist and clinician, internationally, for a quarter of a century. I have helped thousands with their addictions, including hundreds of doctors. I work at a safety-net Addiction Clinic at my hospital at Mass. General Hospital. I specialize in helping individuals and families navigate the complexities of addiction and recovery. I also provide comprehensive medical cannabis consultation for virtually all medical conditions. I also treat cannabis addiction.
Whether you’re exploring cannabis for medical or wellness purposes, or whether you are working to change your relationship with substances (including opioids and alcohol), or looking for sensible harm reduction strategies, I provide expert, compassionate, science-based guidance tailored to your needs. Together, we’ll create a plan that works for you, whether that means moderation, abstinence, mindful use, or finding the right path to recovery.

Cannabis
Medical marijuana or, cannabis, is soaring in popularity, especially among baby boomers and the elderly. It has had its controversies and stigma over the previous decades – largely created by the U.S. government – but millions of people are finding it useful for chronic pain, insomnia, anxiety, PTSD, fibromyalgia, colitis, and a wide variety of medical conditions that our traditional medical system either treats poorly or treats with a high level of toxicity. While there is no “free lunch” with any medicine in terms of side effects, medical cannabis is relatively safe and well-tolerated.

Speaking
Dr. Grinspoon has been a keynote speaker across the globe on many cannabis-related topics, as well as on addiction, opioids, recovery, psychedelics and physician health. According to Dr. Grinspoon, “My best talks are always those in which I go ‘off-script’ and speak extemporaneously, as during those performances my humor and passion shine through.
Cannabis – I am comfortable speaking on any cannabis-related topic to any audience. Popular topics include: medical cannabis in the elderly, cannabis and harm reduction, cannabis and the opioid crisis and medical cannabis for doctors.
Physician Health – I have given grand rounds on this topic at numerous institutions, based on my experiences as a physician in recovery and as an Associate Director of the Physician Health Service in Massachusetts.
Addiction – I come at this issue from all angles, having barely survived an opioid addiction, and as someone who treats doctors and patients for addiction.
Psychedelics – I have been following the ‘psychedelic renaissance’ since age thirteen and have a lifelong interest in psychedelic therapies, as well as lived experience.
