Using Harmless Cigarette is simple and easy. Open the sealed pouch, remove Harmless Cigarette and you're ready to start using it. Enjoy taking gentle puffs, holding it in your mouth or in your hand to help you overcome the urge to smoke when you feel like having a cigarette. Simply puff on Harmless Cigarette the same way as you would puff on any other cigarette, or cigar; and release through your mouth or nose to experience refreshing, relaxing and receiving aromas. (Gentle puffs are sufficient and your mouth does not need to wrap very tightly around it.) No smoke or vapor is inhaled or exhaled.
