Other poisons include: Arsenic, Cyanide, Formaldehyde (used to embalm bodies), Ammonia Bromide (a toilet cleaner )- Ref. 1. Each year, because of exposure to environmental tobacco smoke, an estimated 3,000 nonsmoking Americans die of lung cancer, and 300,000 children suffer from lower respiratory tract infections. Particularly alarming is the fact that more than 3 million young people under age 18 smoke half a billion cigarettes each year and that more than one-half of them consider themselves dependent upon cigarettes. The decision to use tobacco is nearly always made in the teen years, and about one-half of young people usually continue to use tobacco products as adults.

Canada, Australia and New Zealand, however, have both verbal warnings and graphic display of visual images, among other things, the harmful effects of tobacco use on the human body.

Smoke has evolved over the conception, for example, that thin strips crosswise to travel "axis of smoking" (which are thus circles along the length of the cigarette) are alternate sections of paper thin and thick effective combustion to facilitate, when pulled, retard combustion and, when at rest. Synthetic filters remove particles of tar before it reaches the smoker.then rolled or stuffed in a paper-wrapped cylinder (usually less than 120 mm in length and 10 mm in diameter).

Earlier forms of cigarettes have been attested in Central America, around the 9th century, in the form of reeds and tubes of smoking.
