This is a follow up to my last question about marijuana use before a breast reduction.

If you are vaping 24 hours or more prior to surgery, the effects of the marijuana may be gone. However, I would recommend that you not take that chance.  Inform your PS and anesthesiologist of the time you last vaped.Kenneth Hughes, MD, Board Certified Plastic SurgeonLos Angeles, CA

The very fact that you ask means that we all don't know all the negative effects of marijuana and vaping, so why take the chance?  Until someone does a study that shows vaping and pot are safe before surgery, the best course of action for patients is not to take chances with their health.  Incidentally I doubt many patients would ever sign up for such a study, so in truth we may never know.

I would be very surprised if any plastic surgeon would condone the use of marijuana in any form prior to breast reduction. Personally no vaping, no ecigs, no smoking, no nicotine etc.
