i would not recommend it since this has not been tested and i don't know what kind of anesthesia you will be having. i suspect your oral surgeon would not be in favor of you using cannabis before this procedure.
is it dangerous to smoke marijuana 12 hours before surgery? . i will be having all four of my wisdom teeth removed and am wondering if smoking marijuana 12 hours before being put under for surgery would have any negative health effects aside from the typical risks of smoking. thanks!
