What is nicotine lozenge, and what is it used for?

Nicotine is a chemical compound that naturally occurs in tobacco plants. Nicotine is a potent stimulant and a highly addictive substance that is the primary chemical present in all tobacco products. Nicotine stimulates the central nervous system producing rewarding effects, but it is also a toxic chemical that increases heart rate and blood pressure and is associated with hardening of arteries, heart disease, cancers and many other chronic diseases.

Nicotine lozenges are used as nicotine replacement therapy (NRT) to help give up smoking tobacco. Abrupt discontinuation of tobacco products causes nicotine craving and withdrawal symptoms. Nicotine lozenges help relieve the craving and withdrawal symptoms while gradually weaning off nicotine. NRT helps reduce the urge to smoke cigarettes because the body still gets nicotine from another safer method.
