A nicotine inhaler looks like a cigarette. It has a cartridge that contains nicotine. You inhale, and nicotine vapor is absorbed into your mouth and throat area. You don't absorb the nicotine into your lungs like you do with a cigarette. As a result, you don't get the same "hit" of nicotine as with smoking.
Nicotine inhalers are available only by prescription.
You may find a nicotine inhaler helpful if you have trouble breaking free from smoking rituals, such as pulling a cigarette out of the pack, lighting it, putting it in your mouth, and inhaling.
The inhaler does not deliver nicotine as rapidly as a cigarette. The risk of addiction, or of transferring your nicotine habit from cigarettes to the inhaler, is low.
Do not begin to use an inhaler until you have stopped smoking.
A nicotine inhaler kit comes with a nicotine inhaler and cartridges containing nicotine. You place a cartridge into the inhaler and pierce the cartridge to release the nicotine.
It is possible to become dependent on the nicotine inhaler, but this is rare.
There are side effects from using the nicotine inhaler. Read the package insert before you use an inhaler.
