I'm having surgery. How far in advance should I stop taking edibles?

"Should I stop taking CBD oil prior to surgery? If so, how far in advance should I stop?"

There are no established guidelines regarding the matter. However, if vaping the oil and undergoing general anesthesia, in order to reduce the chance of respiratory complications during and after sugery, I recommend that you discontinue for at least one week in advance. Also, very high doses of CBD may possibly reduce the body’s ability to form blood clots. Your anesthesiologist will/should make sure that ability is not compromised. Furthermore, CBD can lower blood pressure, which may also make things a bit trickier for your anesthesiologist. Regardless, you should fully disclose the matter to your surgeon and anesthesiologist. Also, in order to evaluate your specific case properly, I advise that you consult with a medical cannabis physician. This information should not be taken as medical advice.


There are many differing opinions on this topic. Since medical cannabis is relatively new in today’s medicine more research needs to be done in this area. I would consult with your surgeon or anesthesiologist for a recommendation as it may interfere with your anesthesia. I agree with Dr. Kim, you should stop vaping for a least one week before your surgery due to the possibility of respiratory complications.
