Do I need to stop smoking marijuana before my facelift? May I continue to take alpha lipoic acid up until the day of surgery?

Smoking
pre and post-surgery can not only delay healing, but can also increase the risk
of bleeding during the procedure. I always advise patients to ensure that they
are in optimal health prior to any surgery, however minor. Any medication
should be disclosed to your surgeon at consultation stage so that they can
assess risks.

Marijuana has no nicotine but has similar level of carcinogens, carbon monoxide, and bronchial irritants as tobacco therefore it is not recommended within 2 weeks before and after surgery.  There is little in the literature regarding the safety of alpha-lipoic acid in the literature, therefore I would also recommend a 2 week hiatus before and after surgery for this. 

 I don't personally think marijuana smoking would have any effect on the procedure but for pulmonary reasons is probably a good idea not to smoke for a couple weeks prior to the operation. Any medications used  or discontinued before your surgery should be cleared with your own surgeon.
