Nicotine gum is an over-the-counter nicotine replacement therapy approved by the FDA for smoking cessation. It delivers nicotine through the mucous membranes of the mouth rather than through the lungs, giving the body a measured dose without the thousands of harmful chemicals found in cigarette smoke. It comes in two strengths — 2 mg for lighter smokers and 4 mg for heavier smokers — and is used on a structured tapering schedule over several weeks.
When you chew the gum and 'park' it between your cheek and gum, nicotine is absorbed directly into your bloodstream through the mouth lining. This raises blood nicotine levels enough to take the edge off cravings and reduce irritability, anxiety, and restlessness without delivering the rapid nicotine spike that makes cigarettes so addictive. Over time, you gradually use fewer pieces per day, weaning your body off nicotine dependence.
Available as 2 mg (for people who smoke fewer than 25 cigarettes per day) and 4 mg (for heavier smokers). Most brands are sugar-free and come in flavors like mint, cinnamon, and fruit to improve tolerability. Nicotine gum is used on a 'chew and park' technique — not chewed continuously like regular gum — which is essential to proper absorption.
Nicotine gum was developed in Sweden in the 1970s by AB Leo (later acquired by Pharmacia) and first approved in Europe in 1978. The FDA approved it in the United States in 1984, making it the first nicotine replacement therapy available to smokers. It remains one of the most widely studied and prescribed smoking cessation aids in the world.
