What are the effects of smoking and vaping medical marijuana after a bone graft and during the dental implants process?

I'm going to have a closed sinus lifting surgery and dental implants next week. I've heard that you need to avoid smoking cigarettes with dental implants. I'm wondering if it is the action of smoking that slows the healing or is that just nicotine, or both? I don’t smoke nicotine but I am getting treatment with medical marijuana. Whether or not smoking marijuana will greatly affect my implants success? If so, how long I should avoid smoking? What about vaping (vaporizer) marijuana?
