How to Talk to Your Doctor About Cannabis

Most physicians have no formal cannabis training. A practical script for raising it with your primary care provider, what to bring, and what to do if they refuse to discuss it.

The Disclosure Gap Is Dangerous

Nearly half of older adults who use cannabis regularly have not told their doctor. The 2024 University of Michigan National Poll on Healthy Aging, supported by AARP, found that 44% of regular senior cannabis users had not discussed their use with a healthcare provider. Among those who did disclose, 43% brought it up themselves — their providers never asked. Strong evidence

This silence is not merely awkward. It is medically dangerous. The average senior takes five prescription medications, many of which interact with cannabinoids through the CYP450 enzyme system. When your prescribing physician does not know you are using cannabis, they cannot account for those interactions when adjusting doses or adding new medications. A blood thinner like warfarin, a statin, or even an antidepressant can behave very differently in the presence of CBD or THC.

How to Start the Conversation

Many seniors hesitate because they fear judgment, expect dismissal, or worry about being labeled a drug user. These concerns are understandable, but there are practical approaches that work.

Harvard Health recommends starting by expressing interest in "all available treatment options" for your condition. This frames the conversation around symptom management rather than cannabis specifically, and invites your provider into the decision-making process.

Here are three scripts you can adapt:

The Direct Approach

"I have been reading about cannabis for [pain/sleep/anxiety] and I would like to discuss whether it might be appropriate for me, given my current medications."

The Options Approach

"I want to make sure we have looked at all available treatment options for my [condition]. Can we talk about whether medical cannabis is worth considering?"

The Disclosure Approach

"I want to be transparent — I have started using cannabis, and I want to make sure it is safe with my current prescriptions. Can you review my medication list?"

Bring a written list of your current medications, including dosages and frequency. This turns an abstract conversation into a concrete clinical exercise — and it gives your provider something actionable to review.

What to Do If Your Doctor Refuses

A 2017 poll found that few physicians feel equipped to counsel on dosing, CBD-to-THC ratios, or administration methods. If your primary care provider is unwilling or unable to discuss cannabis, you have several options:

  • Ask for a referral. Request a referral to a provider with cannabis medicine training. The Society of Cannabis Clinicians maintains a directory of physicians with additional training.
  • Consult a pharmacist. Pharmacists are often more knowledgeable about drug interactions than physicians. In Pennsylvania, pharmacists are required in all medical cannabis dispensaries. The Penn State CANN-DIR tool (cann-dir.psu.edu) enables any pharmacist to conduct evidence-based interaction screening.
  • Use a cannabis-specialized telehealth service. Platforms like Veriheal (35+ states) and NuggMD (12+ states) connect patients with cannabis-trained physicians.
  • Seek a cannabis nurse. The American Cannabis Nurses Association, recognized by the American Nurses Association in 2023 as a specialty, has trained nurses in cannabis care. Leaf411 operates a free national cannabis-trained nurse hotline.

Regardless of who provides cannabis guidance, always disclose cannabis use to all your healthcare providers — including dentists, specialists, and most critically, anesthesiologists.

Before Surgery: Disclosure Is Not Optional

Cannabis can affect how anesthetics are metabolized. Regular cannabis users may require adjustments to anesthesia protocols. Harvard Health emphasizes that disclosing cannabis use before surgery is essential — not to invite judgment, but because your anesthesiologist needs accurate information to keep you safe during the procedure.

If you are scheduled for any surgical procedure, tell your surgical team about cannabis use during your pre-operative appointment, including how often you use it, what form you use, and when you last consumed it.

A Word About Budtender Advice

Dr. Peter Grinspoon of Harvard Medical School has warned that dispensary staff "are often untrained" and "don't know that older people should be getting very small doses." Dispensary budtenders can help you navigate product selection, but they are not medical professionals. They cannot evaluate your medication list, assess fall risk, or identify contraindications. Moderate evidence

The best approach combines medical guidance from a knowledgeable clinician or pharmacist with product guidance from your dispensary — never one without the other.
