NCBI Bookshelf. This chapter summarizes the state of knowledge about the chemistry and toxicology of cigarette smoke and provides data relevant to the evaluations and conclusions presented in the disease-specific chapters of this report. These commercial products have not been met with widespread consumer acceptance. In most cases, the data reported for chemical levels in mainstream smoke were derived under standard smoking conditions described by the U.

These standard conditions are puff volume of 35 milliliters mL , two-second puff duration, one-minute puff frequency, and butt length defined as either 23 millimeters mm for nonfilter cigarettes or the length of the filter overwrap paper plus 3 mm. When alternative smoking regimens are used, levels of potentially harmful substances in smoke emissions usually differ from those measured under standard conditions.

When people smoke, they do not use the puff volume and puff frequency programmed into smoking machines, and smoking habits vary significantly from person to person and cigarette to cigarette. Consequently, actual exposures to and doses of components of smoke cannot be derived from values obtained with machine smoking. Cigarette smoke is a complex mixture of chemical compounds that are bound to aerosol particles or are free in the gas phase. Chemical compounds in tobacco can be distilled into smoke or can react to form other constituents that are then distilled to smoke.

Researchers have estimated that cigarette smoke has 7, chemical compounds from many different classes Rodgman and Perfetti In assessing the nature of tobacco smoke, scientists must consider chemical composition, concentrations of components, particle size, and particle charge Dube and Green These characteristics vary with the cigarette design and the chemical nature of the product.

Fowles and Dybing suggested an approach to identify the chemical components in tobacco smoke with the greatest potential for toxic effects. They considered the risk for cancer, cardiovascular disease, and heart disease.

Using this approach, these investigators found that 1,3-butadiene presented by far the most significant cancer risk; acrolein and acetaldehyde had the greatest potential to be respiratory irritants; and cyanide, arsenic, and the cresols were the primary sources of cardiovascular risk.

Other chemical classes of concern include other metals, N -nitrosamines, and polycyclic aromatic hydrocarbons PAHs. This evaluation, along with the Hoffmann list of biologically active chemicals Hoffmann and Hoffmann , was used to select the chemicals reviewed in this chapter. Other chemical components with potential for harm will be identified as analysis of tobacco smoke becomes more complete and cigarette design and additives change.

Tobacco smoke is a complex and dynamic chemical mixture. Researchers have analyzed whole smoke or used chemical and physical means to separately examine the gas and particulate portions of tobacco smoke. The gas phase is defined as the portion of smoke that passes through a glass fiber filter of specified physical parameters, and the particulate phase refers to all matter captured by the glass fiber filter Pillsbury Standard methods for analysis of tobacco smoke separate the two phases by using Cambridge glass fiber filters designed to collect aerosol particles of 0.

Although these separate phases are an artificial construct, they are useful for describing the results of analysis of the components of cigarette smoke typically obtained by machine smoking. When people smoke cigarettes, the continuum of physical characteristics in smoke does not include the differentiation into specific fractions. The diameter of cigarette smoke particles constantly changes, and as the particles coalesce after their formation, they grow in diameter.

However, in diluted smoke, loss of a volatile chemical matrix or other components may cause particles to shrink and changes in the particle size may alter the relative amounts of certain chemicals in the gas and particle phases Guerin Smoke formation occurs when the cigarette is lit and a puff is taken or when the cigarette smolders between puffs.

Mainstream smoke is released from the butt end of the burning cigarette during puffing, and sidestream smoke emanates from the burning cigarette coal when it smolders Guerin A greater quantity of sidestream smoke is generated when the amount of tobacco burned during smoldering increases relative to the amount burned during puffing Johnson et al.

Thus, the way the cigarette is smoked e. In addition, the ratio of the levels of chemical components in sidestream smoke to their levels in mainstream smoke can be altered by differences among cigarettes Perfetti et al. These differences are related to the tobacco blend or type, the tobacco preparation e. Studies using a machine that simulates human smoking have determined that the change in the ratio of sidestream to mainstream smoke components after introducing a filter and ventilation primarily resulted from a decrease in the amount of mainstream smoke, because the amount of sidestream smoke does not change substantially with alterations in cigarette design Perfetti et al.

Examination of chemicals with similar properties revealed that those with a low boiling point had higher ratios of levels in sidestream smoke to levels in mainstream smoke and that compounds with a high boiling point had lower ratios Sakuma et al.

With increased puffing intensity, the toxicant ratios of sidestream to mainstream smoke decrease Borgerding et al. The increase in the amount of tobacco burned during smoldering compared with tobacco burned during puffing is not the only factor influencing differences in the chemical content of sidestream and mainstream smoke. The burning conditions that generate sidestream and mainstream smoke also differ Guerin Puffing burns the tobacco on the periphery of the cigarette, and tobacco in the core burns between puffs Johnson ; Hoffmann et al.

Thus, mainstream smoke depends on the chemical composition of the combustible portion of the cigarette near the periphery of the rod, whereas chemicals at higher concentrations in the central portion of the rod have higher levels in sidestream smoke than in mainstream smoke Johnson Sidestream smoke is produced during conditions with less available oxygen Guerin et al.

Ammonia levels are significantly higher in sidestream smoke, resulting in a more alkaline pH Adams et al. Thus, the composition and levels of chemical species in mainstream smoke differ from those in sidestream smoke.

Levels of some compounds are higher in mainstream smoke than in sidestream smoke, and this difference may reflect chemical influences that are more complex than just changes in puff frequency. For example, mainstream smoke contains considerably more cyanide than side-stream smoke does Johnson et al.

Sakuma and colleagues measured a series of semivolatile compounds in tobacco smoke and found that levels of phenol, cresol, xylenols, guiacol, formic acid, and acetic acid were higher in sidestream smoke, whereas levels of catechol and hydroquinone were higher in mainstream smoke. Individual chemical constituents may be found in the particulate phase, the gas phase, or both Guerin The gas phase contains gases and chemical constituents that are sufficiently volatile to remain in the gas phase long enough to pass through the Cambridge glass fiber filter Guerin , but as the filter becomes wet during the first puffs, hydrophilic compounds tend to adhere to it.

The gas phase of cigarette smoke includes nitrogen N 2 , oxygen O 2 , carbon dioxide CO 2 , CO, acetaldehyde, methane, hydrogen cyanide HCN , nitric acid, acetone, acrolein, ammonia, methanol, hydrogen sulfide H 2 S , hydrocarbons, gas phase nitrosamines, and carbonyl compounds Borgerding and Klus ; Rodgman and Perfetti Constituents in the particulate phase include carboxylic acids, phenols, water, humectants, nicotine, terpenoids, paraffin waxes, tobacco-specific nitrosamines TSNAs , PAHs, and catechols.

Mainstream smoke contains only a small amount of nicotine in the gas phase Johnson et al. Brunnemann and colleagues b studied both mainstream and sidestream smoke and found that the gas phase of mainstream smoke contained more cyanide than did the particulate phase. Johnson and colleagues b , however, showed that in sidestream smoke, cyanide is present almost exclusively in the particulate phase.

Guerin concluded that both formaldehyde and cyanide may be present in both phases, and Spincer and Chard found formaldehyde in both the particulate and gas phases. Because physical and chemical changes occur after tobacco smoke is drawn from the cigarette, some of the reported differences in PAH levels could result from differences in measurement techniques.

In summary, cigarette smoke is a complex and dynamic system. The concentration of smoke and the time after it leaves the cigarette can cause changes in particle size that may alter the relative amounts of certain chemicals in the gas and particle phases.

Also, specific properties of the tobacco, the physical design of the cigarette, and the machine-smoking method that is employed to generate mainstream smoke for analyes can have a significant impact on the levels of both mainstream and side-stream emissions.

The tobacco leaf contains many alkaloid chemicals; nicotine is the most abundant. Nicotine content varies, among other factors, by the leaf position on the tobacco stalk and also by the blend or leaf type used in a given cigarette or cigar Tso ; Kozlowski et al. Plants such as tobacco that are characterized by high alkaloid content often possess a natural pharmacologic defense against microorganisms, insects, and vertebrates.

For example, nicotine is toxic to many insects and, for many years, has been extracted from tobacco for use as a commercial pesticide Domino Nicotine is addictive in humans because a portion of the nicotine molecule is similar to acetylcholine, an important brain neurotransmitter Brody et al.

Together, the sum of the concentrations of anatabine, anabasine, and nor-nicotine equals approximately 5 percent of the nicotine concentration Jacob et al. Many minor tobacco alkaloids are pharmacologically active in humans in one or more ways. Clark and colleagues observed that some of these alkaloids had physiological effects in a variety of animal tests. Lefevre reviewed the evidence and concluded that anabasine and nornicotine had demonstrated effects on smooth muscle fiber, blood pressure, and enzyme inhibition.

The literature on potentially addictive properties of these minor alkaloids is limited. S - -nicotine, which is present in the tobacco leaf, is structurally similar to forms of several minor alkaloids also found in the tobacco leaf, such as S - - N -methylanabasine Figure 3. Moreover, Dwoskin and colleagues reported that in the rat, anatabine, anabasine, N -methylanabasine, anabaseine, and nornicotine all release dopamine from striatal brain tissue.

Overall, it is likely that some of the minor tobacco alkaloids could 1 be addictive if delivered alone at sufficiently high levels and 2 act together with nicotine during tobacco use to generate effects that are difficult to discern because nicotine levels are so much higher.

Structures of nicotine and minor alkaloid S - - N -methylanabasine in tobacco leaf. The unprotonated nicotine molecule contains two nitrogen atoms with basic properties. The unprotonated nicotine molecule can thus add one proton to form a monoprotonated species or two protons to form the diprotonated species Figure 3. The first proton added to nicotine attaches predominantly to the nitrogen on the five-membered pyrrolidine ring, because that nitrogen is significantly more basic than the nitrogen on the six-membered pyridine ring.

Although protonated nicotine is not volatile, unprotonated nicotine is volatile and is able to enter the gas phase and readily pass into lipid membranes.

In water or in the droplets of particulate matter in tobacco smoke, the distribution of nicotine among its three forms depends on the pH of the solution. Increasing acidity of the solution increases the fraction of protonated molecules; conversely, increasing basicity increases the fraction in the unprotonated free base form Figure 3. Because all forms of nicotine are highly soluble in water, all of the nicotine entering the respiratory tract from one puff of tobacco smoke easily dissolves in lung fluids and blood.

However, because unprotonated nicotine from tobacco smoke particles is volatile, whereas protonated nicotine is not, a higher percentage of unprotonated nicotine in a puff results in a higher rate of nicotine deposition in the respiratory tract Pankow ; Henningfield et al.

The exact nature and effects of the increased rate of deposition depends on the chemical composition and the size of particles in the tobacco smoke, as well as topographic characteristics of smoking, such as puff size and duration and depth of inhalation.

Increased rates of deposition in the respiratory tract lead to increased rates of nicotine delivery to the brain, which intensify the addictive properties of a drug Henningfield et al.

The conventional view has been that a sample of particulate matter from tobacco smoke is not usually so acidic that the diprotonated form becomes important. At pH 8, the two fractions are present in equal percentages. At any lower pH, the fraction of protonated nicotine is greater.

Because a typical sample of particulate matter from tobacco smoke collected from a cigarette or cigar is mostly nonaqueous liquid, it is not possible to take conventional pH measurements to determine nicotine distribution between the monoprotonated and unprotonated forms Pankow However, it is possible to measure the concentration of unprotonated nicotine in a sample of tobacco smoke particulate c p ,u , because that level produces a directly proportional concentration of unprotonated nicotine in the gas phase, which is measurable Pankow et al.

Some researchers have suggested that the irritation and harshness of smoke at higher pH makes it harder for smokers to inhale this smoke into the lungs Brunnemann and Hoffmann As already noted, nicotine itself is a base. The natural acids in tobacco smoke e. The natural bases e. Variability in the acid-base nature of commercially available tobacco leaf is considerable.

Simple adjustment of the tobacco blend can therefore produce a considerable range of acid or base content in tobacco smoke. The documents reveal that a variety of basic additives have been considered, including ammonia and ammonia precursors. In summary, nicotine in cigarette smoke exists in either a protonated or unprotonated form, depending on a number of factors, including the presence of natural acids and bases, the tobacco blend, tip ventilation, and the use of additives.

Cigarette design ensures that the smoke has enough unprotonated nicotine to rapidly transfer nicotine into the body but not so much of it as to be too harsh for the smoker to continue to smoke.

N -nitrosamines are a class of chemical compounds containing a nitroso group attached to an amine nitrogen. There are two types of nitrosamines in tobacco and tobacco smoke: volatile and nonvolatile, including TSNAs Hoffmann et al.

The volatile nitrosamines include N -nitrosodimethylamine, N -nitrosoethylmethylamine, N -nitrosodiethylamine, N -nitro-sopyrrolidine, and N -nitrosomorpholine.
