We can take nicotine through different sources like cigarettes, nicotine gum and nicotine inhalers. Nowadays many people prefer nicotine inhalers because of its simplicity and ease of use.  The nicotine inhalers are generally available in a cigarette type device which is made up of a cartridge that holds nicotine in it, along with a mouth piece. The nicotine in the inhalers is also mixed up with menthol which provides a good feel while using the inhalers. While using nicotine inhalers a particular amount of air is inhaled through the mouth piece, where it is saturated with nicotine and is absorbed via the lining of the mouth and the upper esophagus.

The absorption time of nicotine through inhalers is slow when compared to regular cigarette. The amount of nicotine in each puff taken through the inhaler is 10 times less the amount of nicotine which is taken through a puff of a cigarette. This nicotine inhaler helps us to control our urge to smoke. The working principle of inhalers is similar to that of nicotine gum, but it uses different design, and the nicotine inhaler starts working faster than nicotine gum.
