How to Talk to Your Doctor About Cannabis - Honest Conversations, Better Care
Many patients hide cannabis use from their physicians out of stigma or fear of judgment. This is medically risky. Cannabis interacts with anesthesia, anticoagulants, antidepressants, immunosuppressants, and more. Honest disclosure leads to safer care. This guide covers how to start the conversation, what your doctor needs to know, and how to interpret different physician responses. Greenleaf Wellness at 1730 Glendale Avenue, Sparks NV is a NV-CCB-licensed retailer - we are not medical providers and do not provide medical advice.

Why disclosure matters
Cannabis is now legally used by ~50 million US adults annually. Despite legalization in NV (2017 adult-use, 2000 medical), only ~30% of patients tell their physicians about cannabis use, per 2022 surveys. The risks of non-disclosure: (1) anesthesia interactions - chronic cannabis users often need more anesthetic and have higher airway reactivity during surgery; (2) drug interactions with warfarin, SSRIs, immunosuppressants, beta-blockers; (3) missed differential diagnoses - cannabinoid hyperemesis syndrome looks like cyclic vomiting; (4) delayed treatment for cannabis use disorder (CUD), which has FDA-treatable comorbidities; (5) inaccurate dose calculations for opioid pain regimens.
What your doctor needs to know
(1) What - flower, edibles, vape, concentrates, tincture, topical. (2) How much - milligrams of THC per session if known; "a bowl" or "a joint" estimate is OK if dose unknown. (3) How often - daily, weekly, occasional, single-event. (4) How long - months, years, decades of use. (5) Why - recreational, sleep, anxiety, pain, appetite, symptom management. (6) Source - NV-licensed dispensary (regulated, lab-tested) vs unlicensed (unverified). (7) Concurrent substances - alcohol, tobacco, prescription medications, supplements. This information is more useful than a binary "yes/no" cannabis answer.
How to open the conversation
Direct approach: "I want to be honest with you - I use cannabis. I'd like to know if it interacts with anything I'm taking or if there's anything I should be careful about."
Symptom-led approach: "I've been using cannabis for [sleep / anxiety / pain / appetite] - can we talk about whether it's helping or hurting?"
Safety-led approach: "I have surgery coming up. I should mention I use cannabis [frequency]. Does this affect anything?"
HIPAA reminder: Your medical record is protected. Disclosed cannabis use cannot be shared with employers, insurance companies (with limited carve-outs), law enforcement, or family members without your consent. NV legalization further reduces stigma in clinical settings.
What if my doctor reacts negatively?
(1) Old-school doctor (rare in NV) - may give an outdated lecture. Stay calm, ask specifically "are there clinical drug interactions I should know about?" - focus on medical facts. (2) Federal employer concerns - VA, military, federal contractor doctors may have additional reporting concerns; ask directly. (3) Tone-deaf advice - "just stop" without acknowledging your reasons. Push for shared decision-making. (4) You can change doctors - in NV, many primary-care physicians and specialists are cannabis-aware. NV cannabis-medical-card physicians are explicitly trained.
Questions to ask your doctor
(1) Drug interactions - "does cannabis interact with [my prescription]?" (2) Surgery prep - "should I stop X days before surgery?" (3) Dose - "is my use level concerning?" (4) Alternatives - "is there a non-cannabis option for [my symptom]?" (5) Drug testing - "will my employer's drug test affect my treatment?" (6) Mental health - "given my [depression/anxiety/family history], is cannabis a risk?" (7) Sleep specifically - "is nightly THC for sleep building tolerance?" (8) Pediatric - "is secondhand cannabis smoke a risk for my child?"
Surgery and anesthesia disclosure
Critical: Anesthesiologists need to know about cannabis use. Recent reviews (Twardowski et al., 2019; Echeverria-Villalobos et al., 2019) document: (1) higher anesthetic doses required for chronic cannabis users (propofol, sevoflurane), (2) increased airway reactivity in chronic smokers, (3) post-op pain may need more opioid management, (4) bleeding risk - some studies show altered platelet function. Many surgical centers ask about cannabis on intake forms; disclose accurately. Withholding info is a real medical risk in the OR.
Pregnancy and breastfeeding disclosure
ACOG (American College of OB-GYN) recommends avoiding cannabis during pregnancy and breastfeeding. THC crosses the placenta and is detectable in breast milk for days to weeks after use. Animal and human observational data link prenatal cannabis to: low birth weight, neurodevelopmental concerns, and altered infant attention. Tell your OB - they can provide non-stigmatizing care and offer alternatives for nausea (medications, ginger, B6) that don't carry fetal exposure risk.
Mental-health disclosure
Cannabis can interact with mental-health conditions. Disclose if you have: (1) schizophrenia, bipolar, or psychosis history (or family history) - heightened psychosis risk; (2) panic disorder - high-dose THC can trigger panic; (3) major depression - daily THC use is associated with worsening depression in some studies; (4) SSRIs/SNRIs/MAOIs - drug interactions; (5) substance use disorders - alcohol use disorder (AUD), opioid use disorder (OUD), tobacco use disorder, all relevant to addiction-medicine care. See cannabis and anxiety FAQ.
Cannabis use disorder (CUD) - when use becomes a problem
CUD affects ~9% of adults who use cannabis (DSM-5 criteria). Signs to discuss with a doctor: (1) tolerance - needing more for the same effect; (2) withdrawal - irritability, sleep disturbance, anxiety, decreased appetite when stopping; (3) lack of control - using more or longer than intended; (4) time/money - significant time spent on cannabis activities; (5) social/occupational impact - missing work, fights with family. Treatment exists: cognitive-behavioral therapy, motivational enhancement, contingency management - and increasingly, telehealth options.
Pain management - opioid alternative or adjunct
Cannabis is a recognized opioid-tapering tool in many pain practices. Patients on chronic opioids who add cannabis often reduce opioid doses by 20–60% (observational data, not RCT-quality). Tell your pain doctor if: (1) you're considering cannabis for pain, (2) you're already using cannabis with opioids - combined respiratory effects matter, (3) you want to taper opioids using cannabis. NV cannabis is not approved for opioid replacement, but pain-medicine physicians increasingly co-manage. See cannabis vs alcohol comparison.
What to bring to your appointment
(1) Product info - bring or photograph the package/COA (Certificate of Analysis). (2) Dose log - 1-week record of mg-THC, frequency, time of day. (3) Symptom journal - what symptom you're treating, severity 1–10 over the week. (4) Medication list - all prescription, OTC, supplements, herbs. (5) Family history - substance use, mental illness, addiction. (6) Specific questions - write 3–5 ahead of time so they don't get forgotten in a 15-minute visit. See cannabis storage FAQ for COA basics.
NV physicians, telehealth, and cannabis-aware clinics
Many NV primary-care physicians, OBs, pain-medicine doctors, and oncologists are cannabis-aware. NV's medical-cannabis card program (since 2000) created a network of physicians explicitly trained in cannabis recommendations. Telehealth options have expanded post-pandemic. If your current physician is dismissive, ask for a referral to a cannabis-aware provider - many work with patients across cannabis, prescription, and lifestyle medicine.
What dispensaries can and can't do
NV CCB-licensed dispensary staff (budtenders) are not medical providers and cannot diagnose, prescribe, or dispense medical advice. We can: (1) describe product cannabinoid/terpene profiles, (2) explain dosing math (mg/serving), (3) help you find products that match what your doctor recommended, (4) provide COA on request, (5) point you to general consumer-education resources. We cannot: diagnose conditions, recommend cannabis as treatment, advise on drug interactions, override what your doctor told you. That's why this conversation matters: get your doctor's input first, then come to us for product matching.
