Nicotine is only one of the ingredients that is found in cigarette smoke.
You have a right to know what the results of any laboratory tests that you consent to. So, I suggest ask your Doctor.
However of more importance is the scientifically proven detrimental effects of smoking on wound healing which can result in poor wound healing that can lead to infections, tissue necrosis (death, dehiscence of the incisions (opening of the incisions), poor scar quality, revision all surgery and a poor result.
Most Plastic surgeons recommend abstinence of smoking 2 weeks before and 6 weeks afterwards (the critical periods of early wound healing).
I trust you have chosen a experienced Plastic Surgeon who is Certified by the American Board of Plastic Surgery and ideally a member of the American Society for Aesthetic Plastic
Surgery (denoting by membership as having met additional criteria and a focus on Cosmetic Plastic Surgery).
