Nicotine Lozenges to Quit Smoking Uses Warnings Side Effects Dosage

nicotine lozenge

Nicotine is a chemical compound naturally found in tobacco plants. It is a potent stimulant and highly addictive substance that is the primary chemical in all tobacco products. Nicotine stimulates the central nervous system, but it is also a toxic chemical associated with heart disease, cancers, and other chronic diseases.

Nicotine lozenges are used as nicotine replacement therapy (NRT) to help quit smoking. Discontinuing tobacco products abruptly causes nicotine craving and withdrawal symptoms. Nicotine lozenges alleviate cravings and withdrawal symptoms while gradually reducing nicotine dependence. NRT reduces the urge to smoke by providing nicotine through a safer method.
