Tobacco Use and Cessation

Use of tobacco is one of the leading causes of preventable illness in the U.S.;¹ smoking accounts for approximately 20% of deaths.²  Although the prevalence of cigarette smoking among U.S. adults from the years 2005 through 2015 declined from 20.9% to 15.1%, including a 1.7% reduction during 2014–2015, this is still higher than the Healthy People 2020 smoking prevalence goal of 12% or less.³ Over 36.5 million adults in the U.S. currently smoke cigarettes and disparities in smoking prevalence persist (e.g., sex, age, race/ethnicity, socioeconomic status, etc.).³ Use of smokeless tobacco (e.g., chewing tobacco or snuff) in 2014 in adults was estimated to be 3.4%, overall; however, nearly 7 in every 100 men (6.7%) reported use compared with fewer than 1 in every 100 women (0.3%).⁴

Use of tobacco-containing products has been associated with both immediate and long-term adverse oral and systemic effects.⁵  Cigarette smoking has been conclusively linked to development of cataract and pneumonia, and accounts for approximately one-third of all cancer deaths.⁶ Cigarette smoking has been linked to about 90% of all cases of lung cancer, which is the leading cause of cancer-related death in both men and women.⁶ Smoking is also associated with oral cancer; cancer of the pharynx, larynx, esophagus, stomach, pancreas, cervix, kidney, and bladder; as well as acute myeloid leukemia.⁶ In addition to cancer, smoking causes pulmonary diseases such as chronic bronchitis and emphysema, and it has been found to worsen asthma symptoms.⁶ About 90% of all deaths from chronic obstructive pulmonary diseases are attributable to cigarette smoking.⁶ It has also been shown that smoking substantially increases the risk of cardiovascular diseases, including stroke, heart attack, vascular disease, and aneurysm.⁶ Smoking causes coronary heart disease, the leading cause of death in the U.S.; cigarette smokers are 2 to 4 times more likely to develop coronary heart disease than those who do not smoke.⁶

There are more than 7,000 chemicals found in the smoke of tobacco products, including nicotine, tar, carbon monoxide, acetaldehyde, and N-nitrosamines.^{5, 6} Nicotine is the primary addicting component.⁶ Smokeless products also contain nicotine, in addition to many other toxic chemicals.⁶ By inhaling tobacco smoke, the average smoker takes in 1 to 2 mg of nicotine per cigarette.⁶ When tobacco is smoked, nicotine rapidly reaches peak levels in the bloodstream and enters the brain. If the smoke is not directly inhaled into the lungs, as with cigar and pipe smokers, or with consumption of smokeless products, nicotine is absorbed through the mucous membranes and reaches peak blood levels and the brain more slowly.⁶ Cigarette smoking produces a rapid distribution of nicotine to the brain, with drug levels peaking within 10 seconds of inhalation.⁶ However, the acute central effects of nicotine dissipate quickly, as do the associated pleasant feelings, compelling people to continue to smoke to maintain the nicotine’s pleasurable effects and prevent withdrawal.⁶

In the central nervous system, nicotine activates neural “reward” pathways that regulate feelings of pleasure.⁶ This activation is mediated through the effects of the neurotransmitter dopamine. Nicotine increases levels of dopamine in the reward circuits, which is a reaction also seen with other drugs of abuse and is thought to be the basis for the pleasurable sensations experienced by many smokers. For many tobacco users, long-term brain changes induced by continued nicotine exposure result in addiction.⁶

Systemically, nicotine stimulates the adrenal glands to release epinephrine.⁶  This epinephrine “rush” causes an increase in blood pressure, respiration, and heart rate.⁶

More than 85% of people who try to quit smoking on their own will experience relapse, most within a week of quitting.⁶ Nicotine withdrawal symptoms include irritability, craving, depression, anxiety, cognitive and attention deficits, disturbed sleep, and increased appetite. Physical symptoms may begin as soon as a few hours after the last cigarette.⁶ Withdrawal symptoms generally peak within the first few days of quitting and usually subside within a few weeks.⁶ For some people, however, symptoms may persist for months.⁶ Although withdrawal is primarily related to the pharmacologic effects of nicotine, many behavioral factors (e.g., the feel, smell, or sight of a cigarette or the ritual involved with obtaining, handling, and lighting a cigarette) are associated with the pleasurable effects of smoking and can also affect the severity of withdrawal symptoms.⁶

Although cigarettes are the most commonly used form of tobacco, other recreational tobacco formulations include conventional smokeless tobacco; newer products like “snus” (i.e., moist, pulverized compressed smokeless tobacco in a small sack) and compressed dissolvable tobacco; cigars; tobacco pipes and water pipes (i.e., hookahs); and electronic cigarettes (e-cigarettes).⁵

Cigarettes, Cigars, and Cigarillos

Cigarettes consist of finely chopped tobacco leaves rolled in a paper wrapper.⁵ Cigarettes may also contain menthol.⁷ In April 2021, the U.S. Food and Drug Administration (FDA) announced its plans to propose tobacco product standards within the next year to ban menthol as a characterizing flavor in cigarettes and ban all characterizing flavors (including menthol) in cigars.^{7, 8}

In addition to the hazards posed by direct inhalation of the smoke (discussed above), cigarettes also affect people exposed to environmental tobacco smoke exhaled during cigarette smoking or accumulated residue on nearby surfaces (i.e., “second-hand smoke”).⁹ Second-hand smoke has been linked to cancer, periodontal disease, respiratory and cardiovascular diseases, as well as adverse health effects among children and infants (e.g., exacerbation of asthma).^{9, 10}

A cigar is a roll of tobacco wrapped in tobacco leaves or other wrapper made of tobacco.^{5, 11} They vary in size—from smaller cigars, such as little filtered cigars or “cigarillos,” to larger, premium cigars. Large cigars can deliver as much as 10 times the nicotine, twice the tar, and more than 5 times the carbon monoxide of a filtered cigarette.¹¹ Little filtered cigars and cigarillos might also contain candy or fruit flavors.¹¹

Conventional Pipes, Water Pipes, or Hookah

Pipe tobacco is generally loose-leaf tobacco smoked in a traditional pipe device with a bowl.¹³ Smoking tobacco from a water pipe, or “hookah,” is a form of smoking traditionally used by men in the Middle East, North Africa, and Asia, but it is growing in popularity worldwide, among both men and women.⁵ Water pipe tobacco, also known as “shisha” or “maassel,” typically consists of shredded tobacco leaves, and often with fruit, spice, or candy flavors.⁵ Although research is limited, existing evidence suggests that the adverse health effects associated with water pipe smoking are similar to those of cigarettes.⁵

In 2019, the FDA authorized via its premarket tobacco product application (PMTA) pathway, the marketing of IQOS™ tobacco heating system (Phillip Morris Products, SA), an electronic device that heats tobacco-filled sticks wrapped in paper to generate nicotine-containing aerosol.¹⁹ The FDA placed stringent marketing restrictions on the products in an effort to prevent youth access and exposure.¹⁹

Conventional and Newer Smokeless Tobacco Products

Conventional smokeless tobacco products are oral snuff and chewing tobacco.⁵ Oral snuff is finely ground tobacco that is available either as a loose product or packaged in tea-bag–like sacks. Snuff users place a small amount, referred to as a “pinch” or “dip,” between the buccal mucosa and gingiva for approximately 30 minutes. Chewing tobacco is coarsely shredded tobacco. Users place a loose-leaf tobacco “chaw,” or compressed tobacco plug, against the buccal mucosa and chew it.⁵ Both oral snuff and chewing tobacco users usually spit out the tobacco-saliva mixture that collects in the mouth; although, more addicted users may intentionally swallow it. Both oral snuff and chewing tobacco contain cancer-causing chemicals, including N-nitrosamines, aromatic hydrocarbons, formaldehyde, and polonium 210.⁵

Snus is a newer commercially available smokeless tobacco formulation product in the U.S. modeled after Swedish snus, which is a relatively low-carcinogen, high-nicotine–content oral snuff contained in small tea-bag–like sachets.⁵ Although Swedish and U.S. snus share a name and appearance, they are manufactured differently and there are differences in the amount of carcinogens and nicotine content. Dissolvable compressed tobacco is a newer smokeless tobacco product made from finely milled tobacco and is available as orbs, lozenges, sticks, and strips.^{5, 14} Some products may resemble candy or mints, toothpicks, or breath strips, and dissolve orally.^{5, 14} Both snus and dissolvable tobacco products are marketed as spitless (“dry”) products and are available in flavors, such as menthol, spice, alcohol, fruit, and candy.⁵

A nicotine-containing pouch product (trade name “Velo” [RJR Vapor Co., LLC]), which began being marketed in 2019, is classified as a tobacco product by the FDA, as it contains nicotine extracted from tobacco; however, the product contains no tobacco leaf.¹⁵

Electronic Nicotine Delivery Systems

Different forms of electronic nicotine delivery systems (ENDS) include electronic cigarettes (e-cigarettes); e-pipes; vaporizers (or “mods”); slim, flash-drive-shaped cartridges; and vape or hookah pens.^{5, 16, 17} E-liquids delivered by these devices typically contain nicotine, propylene or polyethylene glycol, glycerin, and additives, and are available in a wide variety of flavors.^{5, 17} The e-liquid is heated via electric current into an aerosol that the user inhales; this is also termed “vaping.”⁵ E-cigarette use exposes the lungs to a variety of chemicals, both those in contained in the e-liquid fluids, and other chemicals produced during the heating/vaporizing process.¹⁸ A study of some e-cigarette products found the vapor contains known carcinogens and toxic chemicals, as well as potentially toxic metal nanoparticles from the device itself.¹⁹

In October 2021, the FDA announced that it had granted first-ever marketing authorization²⁰ for an e-cigarette product to RJR Vapor Company for its Vuse Solo closed ENDS device and accompanying tobacco-flavored e-liquid pods, specifically, Vuse Solo Power Unit, Vuse Replacement Cartridge Original 4.8% G1, and Vuse Replacement Cartridge Original 4.8% G2. Because the company submitted data to the FDA that demonstrated that marketing of these products is appropriate for the protection of public health, the authorization allows these products to be legally sold in the U.S.²⁰ Under the PMTA pathway, manufacturers must demonstrate that marketing of the new tobacco product would be appropriate for the protection of the public health. These products were found to meet this standard because the agency determined, among other things, that study participants who used only the authorized products were exposed to fewer harmful and potentially harmful constituents (HPHCs) from aerosols compared to users of combusted cigarettes.²⁰ For these products, the FDA determined that the potential benefit to smokers who switch completely or significantly reduce their cigarette use, would outweigh the risk to youth, provided the applicant follows postmarketing requirements aimed at reducing youth exposure and access to the products.²⁰ 

Although it has been suggested that use of e-cigarettes may be a means to assist with quitting regular cigarettes, a population-based study²¹ showed that after 1 year, tobacco smokers who also used e-cigarettes were at increased risk for not being able to quit smoking, compared with smokers who never used e-cigarettes. Findings from a 2021 report of a large, nationally representative cohort study of the Population Assessment of Tobacco and Health Study (conducted 2013 through 2017) do not support the hypothesis that switching to e-cigarettes prevents relapse to cigarette smoking.²²

A 2018 report from the National Academies of Health found a lack of rigorously designed studies examining the effects of e-cigarettes on oral health, as well as “no epidemiological studies examining the associations between e-cigarette use and incidence or progression of periodontal disease.”²³ The report also found that “human studies and in vitro studies suggest that e-cigarette aerosols can cause harm to oral health by inducing gingival inflammation in the oral cavity,” but that other studies suggest “that e-cigarette use may be less harmful to oral health than continued smoking of combustible tobacco cigarettes.” There is a need to better understand the health effects of vaping, and especially the impact of vaping on the oral cavity.²⁴

According to the U.S. Centers for Disease Control and Prevention (CDC), during 2015, 68% of adult smokers wanted to stop smoking, 55.4% had made a past-year quit attempt, 7.4% had recently quit smoking, 57.2% had been advised by a health professional to quit, and 31.2% used cessation counseling and/or medication when trying to quit.²⁵ The 2008 U.S. Public Health Service clinical practice guideline for treating tobacco use and dependence²⁶ found that counseling and medication are effective when used by themselves for treating tobacco dependence; however, the combination of counseling plus medication was more effective than either method alone.

Behavioral/Nonpharmacologic

According to the 2008 U.S. Public Health Service-sponsored clinical practice guideline,²⁶ individual, group, and telephone counseling are effective strategies for tobacco cessation, and their effectiveness increases with treatment intensity. Practical counseling (i.e., problem-solving/skills training) and provision of social support during treatment were two components of counseling considered especially effective.  The guideline also found evidence for the effectiveness of broad-reach telephone “quitline” counseling for diverse populations.²⁶ In the U.S., telephone counseling is available free through a system of state-based quitlines accessible with one toll-free number (1-800-QUIT-NOW [784-8669]).⁶

Cognitive behavioral therapy has been shown to improve the success rate of smokers who are ready and willing to quit.²⁷ Programs enhance motivation, bolster social support, and teach smokers to identify and manage nicotine withdrawal symptoms, cravings, and tempting situations.²⁷ Other nonpharmacologic tobacco cessation strategies with some evidence of efficacy include hypnotherapy (i.e., hypnosis) and acupuncture.²⁸

Pharmacologic

According to the CDC,²⁵ use of cessation medications is appropriate for most adult smokers, with the exception of pregnant women, light smokers (i.e., persons who smoke fewer than 5 to 10 cigarettes daily), and persons with specific medical contraindications (e.g., seizure disorders²). Nicotine-replacement therapy, bupropion (an atypical antidepressant), and varenicline (a selective nicotine receptor partial agonist) are first-line pharmacologic therapies to assist with smoking cessation recommended by the U.S. Department of Health and Human Services (Table).¹

A 2014 summary of 12 Cochrane reviews²⁹ looking at efficacy and harms of pharmacologic therapies for smoking cessation used network meta-analysis to make direct and indirect comparisons of efficacy between nicotine-replacement therapy, bupropion, and varenicline for smoking cessation.  The review found higher abstinence rates with nicotine-replacement therapies (17.6%) and bupropion (19.1%), compared with placebo (10.6%). Varenicline (27.6%) and combination nicotine-replacement therapies²⁷ (e.g., longer-acting patch plus short-acting inhaler, 31.5%) were most effective for achieving smoking cessation. The analysis found that none of the therapies was associated with an increased rate of serious adverse events.

Oral Effects of Tobacco/Nicotine Use

All of the major forms of tobacco used in the U.S. have oral health consequences.³⁶ Cigarette smoking can lead to a variety of adverse oral effects, including gingival recession, impaired healing following periodontal therapy, oral cancer, mucosal lesions (e.g., oral leukoplakia, nicotine stomatitis), periodontal disease, and tooth staining.^{5, 36} Use of smokeless tobacco is associated with increased risks of oral cancer and oral mucosal lesions (e.g., oral leukoplakia).^{5, 36} Smokeless tobacco use also causes oral conditions such as gingival keratosis, tooth discoloration, halitosis, enamel erosion, gingival recession, alveolar bone damage, periodontal disease, coronal or root-surface dental caries due to sugars added to the product, and tooth loss.⁵

In addition to its systemic effects, described previously, nicotine, especially that contained in nicotine replacement therapies, can have various local oral effects, including local burning sensation, throat irritation, dry lips, and mouth ulcers (depending on the formulation/method of administration); however, the local effects of nicotine replacement therapy are generally mild and self-limited.³⁷ Nicotine itself is not considered a direct carcinogen, but may act as a tumor promoter.^{23, 38} A 2019 systematic review of the literature examined the specific effect of nicotine on gingival, periodontal ligament, and oral epithelial cells in in vitro models.³⁹ The review found that nicotine found at levels in tobacco smoke, nicotine replacement therapy, and e-cigarettes was unlikely to be cytotoxic to oral tissues, while saliva levels with smokeless tobacco use may be potentially cytotoxic; however, data were limited and, in some cases, contradictory.³⁹

Cessation Counseling

Because of the oral health implications of tobacco use, dental practices may provide a uniquely effective setting for tobacco use recognition, prevention, and cessation.²⁴ Health-care professionals, including dental professionals, can help smokers quit by consistently identifying patients who smoke, advising them to quit, and offering them information about cessation treatment.²⁵ The U.S. Department of Health and Human Services and Agency for Healthcare Research and Quality has published a 5-step algorithm for health-care professionals to use when engaging patients who are dependent on nicotine called “the 5As.”⁴⁰ The 5 steps are as follows:

1. Ask:  Identify and document tobacco use status for every patient at every visit.
2. Advise:  In a clear, strong, and personalized manner, urge every tobacco user to quit.
3. Assess:  Is the tobacco user willing to make a quit attempt at this time?
4. Assist: For the patient willing to make a quit attempt, use counseling and pharmacotherapy to help him or her quit. 
5. Arrange:  Schedule follow-up contact, in person or by telephone, preferably within the first week after the quit date.

While there is an ADA Seal product category for tobacco cessation products, to date, no tobacco cessation products have earned the ADA Seal of Acceptance. In evaluating products for the ADA Seal of Acceptance, the Council on Scientific Affairs determines whether the product complies with its Guidelines for Participation in the ADA’s Seal of Acceptance Program and the applicable ADA Acceptance Program Product Requirement. These requirements describe the clinical, biological, and laboratory studies necessary to evaluate safety and efficacy.
