QUIT AIDS
Some quit aids have nicotine in them. These products are called nicotine replacement therapy (or NRT). Others do not contain nicotine and come as tablets. Depending on the type of product and country, these cessation aids might be available over the counter at pharmacies or supermarkets or require a prescription.

Nicotine patches release nicotine into the bloodstream through the skin.
GUM
Nicotine gum releases nicotine as you chew, which is then absorbed through the lining of the mouth.
LOZENGES
Nicotine lozenges release nicotine as they dissolve in the mouth.
MICROTABS
These small nicotine tablets dissolve under the tongue.
NASAL SPRAYS
Nicotine nasal sprays deliver nicotine through the nose lining.
THERAPIES WITHOUT NICOTINE
They come in the form of tablets and are usually prescription only.
