The cigar presents a unique paradox in tobacco consumption, as it is a product designed to be smoked without drawing the smoke into the lungs. This practice contrasts sharply with cigarette smoking, where deep inhalation is the norm for nicotine delivery. A cigar is fundamentally a tightly rolled bundle of dried and fermented tobacco leaves. The non-inhalation method suggests the purpose of the experience lies in mechanisms other than rapid lung-based nicotine absorption.
Nicotine Delivery Through Oral Absorption
The primary physiological reason a cigar smoker does not need to inhale is the chemical environment created by the tobacco itself. Cigar tobacco undergoes extensive fermentation, resulting in smoke with an alkaline, or high, pH level. This alkalinity is a significant factor in how nicotine is absorbed into the body.
The smoke from large cigars can have a pH value around 6.10 or higher, with some reaching up to 8.5, notably higher than the acidic smoke of most cigarettes. This high pH converts the nicotine within the smoke into its “freebase” form. Freebase nicotine is unprotonated, meaning it readily passes through the body’s lipid membranes.
Because of this chemical property, nicotine does not require the large surface area of the lungs for efficient absorption. Instead, it is easily absorbed through the mucous membranes lining the mouth, known as the buccal cavity. This process results in a slower, steadier release of nicotine into the bloodstream, satisfying the user without the need for a harsh, deep draw.
The Importance of Flavor and Aroma
Not inhaling is deeply connected to the sensory experience of the product, beyond the physiological mechanism of nicotine absorption. Cigar tobacco is aged and fermented, a process similar to fine wine or tea, which develops complex flavors influenced by the soil and climate, a concept known as terroir. The smoke is deliberately drawn into the mouth and held there to allow the palate to register these nuanced flavor compounds.
The smoker tastes the smoke across the tongue, and olfactory receptors are engaged by retrohaling. This technique involves gently pushing a small amount of smoke out through the nasal passages, exposing the olfactory bulb to the smoke’s full aromatic profile. Since the sense of smell contributes significantly more to flavor perception than taste buds alone, this practice unlocks subtle notes like earthiness, leather, spice, or floral characteristics.
This sensory ritual transforms the experience into a contemplative appreciation of the tobacco’s blend and craftsmanship. The slower, deliberate pace of smoking a cigar encourages a focus on these flavors and aromas, contrasting sharply with the quick nicotine dose sought by a cigarette smoker.
Cigar Construction and Smoking Technique
The physical characteristics of a cigar also dictate the non-inhalation technique, as the smoke produced is too irritating for the lungs. A cigar is constructed from three layers—the filler, the binder, and the wrapper—all made of dense, air-cured tobacco leaf. This compact construction results in a thick, concentrated smoke.
The smoke’s high alkalinity, which facilitates buccal nicotine absorption, also makes it intensely irritating to the delicate tissues of the throat and lungs. The smoke is harsh and spicy, causing a burning sensation if inhaled deeply, serving as a natural deterrent. The technique itself is a simple “puffing” action, where the smoker draws the smoke into the mouth only.
Preparation and Draw
A crucial part of the process is the initial preparation, which involves cutting the cap end of the cigar to create a clean opening, followed by slowly lighting the foot. The smoker must puff periodically to maintain the proper burn rate, drawing the smoke into the oral cavity but not beyond. This controlled draw ensures the cigar burns evenly and provides a consistent flow of flavor without overheating the tobacco, which would otherwise turn the flavor bitter.
Specific Health Risks of Oral Tobacco Exposure
Despite the common practice of not inhaling, cigar smoking still carries significant health risks concentrated in the upper body. The belief that non-inhalation makes the product safe is a misconception. The lips, tongue, mouth, throat, and esophagus are still directly exposed to toxic compounds. Cigar smoke contains many of the same carcinogens found in cigarette smoke, often in higher concentrations, including cancer-causing nitrosamines.
The prolonged contact of the smoke and the saliva, which absorbs the carcinogens, significantly increases the risk of localized cancers. Cigar smokers face elevated risks for localized cancers, including:
- Cancers of the lip, tongue, and cheek.
- Laryngeal cancers.
- Pharyngeal cancers.
Swallowing the carcinogen-laden saliva also exposes the esophagus to these toxins, raising the risk of esophageal cancer.
Furthermore, exposure to hot smoke and toxic constituents affects oral health beyond cancer risk. Cigar smokers have an increased likelihood of developing periodontal disease, which can lead to gum recession and tooth loss. While the risk of lung cancer is lower for exclusive cigar smokers who do not inhale, the risks to the entire upper digestive and respiratory tracts remain comparable to those of cigarette users.
