Yes, you should definitely let your doctor know.
Even though you aren’t combusting plant matter or inhaling smoke, medical professionals use the general label of “smoker” or “substance user” on health charts to account for anything that enters your lungs or affects your system.
Here is why it’s important to share this with your physician:
1. Lung and Airway Health
While vaping eliminates tar and carbon monoxide from combustion, inhaling aerosolized vapor (which contains terpenes, carrier oils, and active cannabinoids) can still impact your airways. If you ever present with a cough, chest tightness, or respiratory issues, knowing you vape helps your doctor accurately evaluate your lungs.
2. Medication and Anesthesia Interactions
THC interacts with how your body metabolizes certain pharmaceuticals. More importantly, if you ever undergo a medical procedure requiring sedation or anesthesia, THC affects the amount of anesthesia required to keep you safely asleep and managed for pain.
3. Accurate Health Records
Doctors aren’t there to judge or report you; they just need an accurate picture of your biology. You can explicitly clarify to them: “I don’t smoke tobacco or flower, but I use a THC vape.” They will usually make a note of the specific method so you aren’t incorrectly miscategorized as a traditional cigarette or heavy smoke inhaler.
Tip for your appointment: Be direct about how often you vape and what type of product you use (e.g., regulated dispensary cartridges vs. other sources), as product safety and purity are key details for your health history.
