Can you vape with 50 mg nicotine after wisdom tooth extraction? if no then how long should i wait? i have heard from friends you can vape through the nose and it wont affect you?

The problem with nicotine is that it gets into your bloodstream & goes to the tiny blood vessels that decide how fast you heal. It constricts/narrows them reducing blood flow. If you don't care how long it takes to heal vape and ignore the risk. If you wan to get past this quicker take a break for a few weeks until you decide healing is coming along fine. The nose thing is a myth.

You can not avoid vaping smoke to enter in to fresh extraction socket ,The best advise is to wait at least Four to six weeks for complete healing or even more depending on healing .

Do not vape, through the nose or otherwise. Nicotine is getting into your bloodstream and messing with your brain. By vaping you are putting yourself at the risk of all the diseases that tobacco use entails. Quit vaping while you are ahead.
