Nicotine Gum as an Effective Smoking Cessation Aid

What is Nicotine Gum?
Nicotine gum is a chewing gum that contains nicotine in order to help smokers satisfy their nicotine cravings without needing to smoke. The gum works by slowly releasing nicotine into the bloodstream when chewed, providing smokers with the nicotine they are accustomed to receiving from cigarettes. Unlike cigarettes however, nicotine gum does not contain any of the other harmful chemicals found in tobacco smoke.

How Nicotine Gum Works
When a smoker puts a piece of Nicotine Gum in their mouth and begins chewing, nicotine is released from the gum and absorbed through the lining of the mouth into the bloodstream. This delivery of nicotine provides the "hit" that smokers are used to receiving from cigarettes that satisfies nicotine cravings. However, because nicotine from gum is absorbed more slowly than from smoking, it produces a lower peak blood nicotine level and fewer withdrawal symptoms compared to abruptly quitting smoking. As the smoker continues using nicotine gum, they can gradually reduce their intake of nicotine over time as their dependence lessens. The overall goal is to provide enough nicotine through gum to make smoking unnecessary.

Availability and Dosing Instructions
Nicotine gum comes in different strengths - 2 mg and 4 mg. The 2 mg gum is usually recommended for heavy smokers (more than 25 cigarettes per day) when starting a quit attempt, switching to the 1 mg gum after 6 weeks and then stopping gum use completely after 3 months. Lighter smokers (less than 25 cigarettes per day) often begin with the 2 mg gum, switching to the 1 mg gum after 2-4 weeks before stopping.

It is important for smokers using nicotine gum to follow directions closely regarding how long to chew each piece. Standard instructions recommend chewing each piece of gum slowly for 30 minutes, then discarding it. The gum should not be chewed like regular chewing gum - it should be "parked" between the cheek and gum and chewed occasionally instead of continuously to enable slow nicotine absorption. Too much or too rapid chewing could result in nicotine overdose symptoms like nausea.

Effectiveness for Smoking Cessation
Numerous clinical studies have demonstrated nicotine gum's effectiveness as a smoking cessation tool. Studies have found it can help smokers double or triple their chances of successfully quitting compared to trying to quit cold turkey without any nicotine replacement therapy. However, its success rates are still modest - around 15-30% of all individuals who try to quit with nicotine gum remain abstinent after 6-12 months.

Factors like compliance with directions and level of dependence affect outcomes. When used as directed, over-the-counter nicotine gum can provide support similar to prescription nicotine therapies like the patch or lozenge. Combining gum with counseling is often even more effective. Although stopping smoking completely is challenging, nicotine gum offers a proven option for smokers motivated to gradually wean themselves off cigarettes.

Safety and Side Effects
Nicotine gum is generally a very safe product when used as directed. However, some potential side effects may occur due to excess nicotine absorption:

- Nausea: Chewing too rapidly or using too many pieces at once can cause stomach upset.

- Hiccups and Heartburn: Excess swallowing of nicotine-containing saliva may irritate the esophagus in some cases.

- Jaw Soreness: Prolonged chewing may result in jaw ache or tiredness.

- Headaches: Nicotine withdrawal when reducing gum use too quickly can trigger headaches.

- Insomnia: Nicotine is a stimulant and may disrupt sleep if used too close to bedtime.

These side effects are usually mild and temporary, disappearing once gum use is adjusted. Nicotine overdose severe enough to require medical attention is very rare when instructions are followed closely. However, nicotine gum should not be used by pregnant women or those with serious medical conditions without consulting a healthcare provider first.

Alternatives to Nicotine Gum
While nicotine gum remains a proven and widely available option, newer forms of nicotine replacement therapy are available as alternatives. The nicotine patch provides continuous nicotine absorption through the skin for 16 or 24 hours to satisfy cravings. Nicotine lozenges and strips work similarly but offer the oral satisfaction of chewing or sucking. Electronic cigarettes or vaping devices also deliver nicotine without combustible smoke. Prescription non-nicotine quit smoking medications like Chantix (varenicline) and Zyban (bupropion) can additionally help by reducing cravings and withdrawal symptoms. Quitlines and behavioral support increase success rates even further when combined with medication therapy.
