Since it is prohibited to smoke in public places, and as I always need my dose of nicotine I've started to sniff cigarette powder so as not to be deficient of nicotine. How this good or not? I don't have any idea about it but this helps me to fight the desire.
The risks: cancer of the upper aero digestive tract, cancer of the lips, cancer of the tong, pharynx or laryngeal cancer. Better for you to find a way to stop. Snuff or smoking will result in destroying your life.
