The burn rate of cigarette paper is regulated through the application of different forms of microcrystalline cellulose to the paper.[139] Cigarette paper has been specially engineered by creating bands of different porosity to create "fire-safe" cigarettes.

The so-called "shower curtain law" was passed in 2002 to hide cigarettes from children, but was struck down a year later by an appeals court. ^

One of the classes of chemicals on the list, ammonia salts, convert bound nicotine molecules Per mezzo di tobacco smoke into free nicotine molecules.

The earliest forms of cigarettes were similar to their predecessor, the cigar. Cigarettes appear to have had antecedents Per Mexico and Central America around the 9th century Per the form of reeds and smoking tubes. The Maya, and later the Aztecs, smoked tobacco and other psychoactive drugs Per mezzo di religious rituals and frequently depicted priests and deities smoking on pottery and temple engravings.

The other process of degradation is photodegradation, which is when a molecular bond is broken by the absorption of photon radiation (i.e. light). Paio to cellulose acetate carbonyl groups, the molecule naturally absorbs light at 260 nm,[180] but it contains some impurities which can absorb light. These impurities are known to absorb light Per mezzo di the far UV light region (< 280 nm).[181] The atmosphere filters radiation from the sun and allows radiation of > 300 nm only to reach the surface. Thus, the primary photodegradation of cellulose acetate is considered insignificant to the total degradation process, since cellulose acetate and its impurities absorb light at shorter wavelengths. Research is focused on the secondary mechanisms of photodegradation of cellulose acetate to help make up for some of the limitations of biodegradation.

Some cigarettes are marketed as "lights", "milds", or "low-tar".[198] These cigarettes were historically marketed as being less harmful, but there is risposta negativa research showing that they are any less harmful. The filter stile is one of the main differences between light and regular cigarettes, although not all cigarettes contain perforated holes Con the filter. Per some light cigarettes, the filter is perforated with small holes that theoretically diffuse the tobacco smoke with clean air.

The papers used in tipping the cigarette (forming the mouthpiece) and surrounding skontrolujte moju referenciu the filter stabilize the mouthpiece from saliva and moderate the burning of the cigarette, as well as the delivery of smoke with the presence of one or two rows of small laser-drilled air holes.[32] Tobacco blend

[30] While the assembly of cigarettes is straightforward, much focus is given to the creation of each of the components, Con particular the tobacco blend. A key ingredient that makes cigarettes more addictive is the inclusion of reconstituted tobacco, which has additives to make nicotine more volatile as the cigarette burns.[31]
