Some quit-smoking 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.
Whatever the method, what matters most is quitting.
Below are some examples of smoking cessation aids:
Nicotine patches release nicotine into the bloodstream through the skin.
Nicotine gum releases nicotine as you chew, which is then absorbed through the lining of the mouth.
Nicotine lozenges release nicotine as they dissolve in the mouth.
• Therapies without nicotine
They come in the form of tablets and are usually prescription only.
