Like I know you’re not supposed to smoke before surgery and always tell your dr when you last smoked but how does it effect the anesthesia?

Answer 1

Marijuana relaxes your central nervous system. Anesthesia also relaxes your central nervous system. If you’re high at the time of surgery, doctors may want to use less anesthesia because the marijuana would already be doing something similar to the anesthesia. If you’re not high but you use marijuana regularly, your body may be more used to the effects of these sorts of substances, so more anesthesia may be needed to put you to sleep.
