When is it safe to vape after wisdom teeth removal?

Vaping of any nicotine product is known to cause reduced blood flow through capillaries. Adequate blood flow is necessary for natural healing. Many surgical specialties will decline to do elective operations on those with a vaping habit because of poor healing. Safety is a relative construct. It is safest never to vape.

Never. Vaping has been implicated in destruction of your lung's alveoli. It has been implicated in slowing the healing process. You've made aa good start at curing your addiction. See it through to optimum health.
