The smoking age is the minimum legal age required to purchase or use tobacco or cannabis products. Most countries have laws that forbid sale of tobacco products to persons younger than certain ages, usually the age of majority or the drinking age .
This article does not discuss laws that regulate electronic cigarettes.
In law, a minor is someone under a certain age, usually the age of majority, which demarcates an underage individual from legal adulthood. The age of majority depends upon jurisdiction and application, but it is commonly 18. Minor may also be used in contexts that are unconnected to the overall age of majority. For example, the smoking and drinking age in the United States is 21, and younger people below this age are sometimes called minors in the context of tobacco and alcohol law, even if they are at least 18. The terms underage or minor often refer to those under the age of majority, but may also refer to a person under other legal age limits, such as the age of consent, marriageable age, driving age, voting age, working age, etc. Such age limits are often different from the age of majority.
The concept of minor is not sharply defined in most jurisdictions. The age of criminal responsibility, of ability to legally consent to sexual activity, at which school attendance is no longer compulsory and thus a person may leave school, at which legally-binding contracts may be entered into, and so on and so forth, may be different from one another.
A cigarette is a thin cylinder of tobacco rolled in thin paper for smoking. The cigarette is ignited at one end, causing it to smolder, and the resulting smoke is orally inhaled via the opposite end. Cigarette smoking is the most common method of tobacco consumption. The term cigarette refers to a tobacco cigarette, but the word is sometimes used to refer to other substances, such as a cannabis cigarette or a herbal cigarette. A cigarette is distinguished from a cigar by its usually smaller size, use of processed leaf, different smoking method, and paper wrapping, which is typically white.
Deaths from smoking cigarettes are caused by diseases such as cancer, chronic obstructive pulmonary disease (COPD), heart disease, birth defects, and other health problems relating to nearly every organ of the body. Most modern cigarettes are filtered, but this does not make the smoke inhaled from them contain fewer carcinogens or harmful chemicals. Nicotine, the psychoactive drug in tobacco, makes cigarettes highly addictive. About half of cigarette smokers die of tobacco-related disease and lose on average 14 years of life. Every year, cigarette smoking causes more than 8 million deaths worldwide; more than 1.3 million of these are non-smokers dying as a result of exposure to secondhand smoke. These harmful effects have led to legislation that has prohibited smoking in many workplaces and public areas, regulated marketing and purchasing age of tobacco, and levied taxes to discourage cigarette use.
