products

Tobacco is an agricultural product processed from the fresh leaves of plants in the genus Nicotiana. The genus contains a number of species, however, Nicotiana tabacum is the most commonly grown. Nicotiana rustica follows as second containing higher concentrations of nicotine. These leaves are harvested and cured to allow for the slow oxidation and degradation of carotenoids in tobacco leaf. This produces certain compounds in the tobacco leaves which can be attributed to sweet hay, tea, rose oil, or fruity aromatic flavors. Before packaging, the tobacco is often combined with other additives in order to: enhance the addictive potency, shift the products pH, or improve the effects of smoke by making it more palatable. In the United States these additives are regulated to 599 substances. The product is then processed, packaged, and shipped to consumer markets. Means of consumption has greatly expanded in scope as new methods of delivering the active substances with fewer by-products have encompassed or are beginning to encompass:
Field of tobacco organized in rows extending to the horizon.
Tobacco field in Intercourse, Pennsylvania.
Powderly stripps hung vertically, slightly sun bleached.
Basma leaves curing in the sun at Pomak village of Xanthi, Thrace, Greece.
Rectangular strips stacked in an open square box.
Processed tobacco pressed into long strips for shipping.

Beedi
    Beedis are thin South Asian cigarettes filled with tobacco flake and wrapped in a tendu leaf tied with a string at one end. They produce higher levels of carbon monoxide, nicotine, and tar than cigarettes typical in the United States.

Cigars
    Cigars are tightly rolled bundles of dried and fermented tobacco which are ignited so that smoke may be drawn into the smoker's mouth. They are generally not inhaled because the high alkalinity of the smoke, which can quickly become irritating to the trachea and lungs. The prevalence of cigar smoking varies depending on location, historical period, and population surveyed, and prevalence estimates vary somewhat depending on the survey method. The United States is the top consuming country by far, followed by Germany and the United Kingdom; the US and Western Europe account for about 75% of cigar sales worldwide. As of 2005 it is estimated that 4.3% of men and 0.3% of women smoke cigars in USA.

Cigarettes
    Cigarettes, French for "small cigar", are a product consumed through smoking and manufactured out of cured and finely cut tobacco leaves and reconstituted tobacco, often combined with other additives, which are then rolled or stuffed into a paper-wrapped cylinder. Cigarettes are ignited and inhaled, usually through a cellulose acetate filter, into the mouth and lungs.

Electronic cigarette
    Electronic cigarettes are an alternative to tobacco smoking, although no tobacco is consumed. It is a battery-powered device that provides inhaled doses of nicotine by delivering a vaporized propylene glycol/nicotine or vegetable glycerin/nicotine solution. Many legislation and public health investigations are currently pending in many countries due to its relatively recent emergence. Most electronic cigarettes are designed to resemble actual tobacco smoking implements, such as cigarettes, cigars, or pipes, but many take the form of ballpoint pens or screwdrivers since those designs are more practical to house the mechanisms involved. Most are also reusable, with replaceable and refillable parts, but some models are disposable.

French inhale
    The French inhale is the action performed by smokers of expelling smoke from the mouth and inhaling it into the nostrils.

Hookah
    Hookah are a single or multi-stemmed (often glass-based) water pipe for smoking. Originally from India. The hookah was a symbol of pride and honour for the landlords, kings and other such high class people. Now,the hookah has gained immense popularity, especially in the Middle East. A hookah operates by water filtration and indirect heat. It can be used for smoking herbal fruits, tobacco, or cannabis.
Kretek
    Kretek are cigarettes made with a complex blend of tobacco, cloves and a flavoring "sauce". It was first introduced in the 1880s in Kudus, Java, to deliver the medicinal eugenol of cloves to the lungs. The quality and variety of tobacco play an important role in kretek production, from which kretek can contain more than 30 types of tobacco. Minced dried clove buds weighing about 1/3 of the tobacco blend are added to add flavoring. In 2004 the United States prohibited cigarettes from having a "characterizing flavor" of certain ingredients other than tobacco and menthol, thereby removing kretek from being classified as cigarettes.
Passive smoking
    Passive smoking is the usually involuntary consumption of smoked tobacco. Second-hand smoke (SHS) is the consumption where the burning end is present, environmental tobacco smoke (ETS) or third-hand smoke is the consumption of the smoke that remains after the burning end has been extinguished. Because of its perceived negative implications, this form of consumption has played a central role in the regulation of tobacco products.
Pipe smoking
    Pipe smoking typically consists of a small chamber (the bowl) for the combustion of the tobacco to be smoked and a thin stem (shank) that ends in a mouthpiece (the bit). Shredded pieces of tobacco are placed into the chamber and ignited. Tobaccos for smoking in pipes are often carefully treated and blended to achieve flavour nuances not available in other tobacco products.
Roll-Your-Own
    Roll-Your-Own or hand-rolled cigarettes, often called 'rollies', are very popular particularly in European countries. These are prepared from loose tobacco, cigarette papers, and filters all bought separately. They are usually much cheaper than ready-made cigarettes.
Vaporizer
    A vaporizer is a device used to sublimate the active ingredients of plant material. Rather than burning the herb, which produces potentially irritating, toxic, or carcinogenic by-products; a vaporizer heats the material in a partial vacuum so that the active compounds contained in the plant boil off into a vapor. Medical administration of a smoke substance often prefer this method as to directly pyrolyzing the plant material.
