[交流] something about smoking


something about smoking


difinition
引用回帖:
Smoking is a practice in which a substance, most commonly tobacco or cannabis, is burned and the smoke is tasted or inhaled. This is primarily practised as a route of administration for recreational drug use, as combustion releases the active substances in drugs such as nicotine and makes them available for absorption through the lungs. It can also be done as a part of rituals, to induce trances and spiritual enlightenment.

the history
引用回帖:
The history of smoking can be dated to as early as 5000 BC, and has been recorded in many different cultures across the world. Early smoking evolved in association with religious ceremonies; as offerings to deities, in cleansing rituals or to allow shamans and priests to alter their minds for purposes of divination or spiritual enlightenment. After the European exploration and conquest of the Americans, the practice of smoking tobacco quickly spread to the rest of the world. In regions like India and Subsaharan Africa, it merged with existing practices of smoking (mostly of cannabis). In Europe, it introduced a new type of social activity and a form of drug intake which previously had been unknown.

Substances and equipment
引用回帖:
The most popular type of substance that is smoked is tobacco. There are many different tobacco cultivars which are made into a wide variety of mixtures and brands. Tobacco is often sold flavored, often with various fruit aromas, something which is especially popular for use with water pipes, such as hookahs. The second most common substance that is smoked is cannabis, made from the flowers or leaves of Cannabis sativa or Cannabis indica. The substance is considered illegal in most countries in the world and in those countries that tolerate public consumption, it is usually only pseudo-legal. Despite this, a considerable percentage of the adult population in many countries have tried it with smaller minorities doing it on a regular basis. Since cannabis is illegal or only tolerated in most jurisdictions, there is no industrial mass-production of cigarettes, meaning that the most common form of smoking is with hand-rolled cigarettes (often called joints) or with pipes. Water pipes are also fairly common, and when used for cannabis are called bongs.

and as we all know, smoking is bad to health
引用回帖:
Tobacco-related diseases are some of the biggest killers in the world today and are cited as one of the biggest causes of premature death in industrialized countries.[citation needed] In the United States about 500,000 deaths per year are attributed to smoking-related diseases and a recent study estimated that as much as 1/3 of China's male population will have significantly shortened life-spans due to smoking.[36] Male and female smokers lose an average of 13.2 and 14.5 years of life, respectively.[37] At least half of all lifelong smokers die earlier as a result of smoking.[38][39]The risk of dying from lung cancer before age 85 is 22.1% for a male smoker and 11.9% for a female current smoker, in the absence of competing causes of death. The corresponding estimates for lifelong nonsmokers are a 1.1% probability of dying from lung cancer before age 85 for a man of European descent, and a 0.8% probability for a woman.[40] Smoking one cigarette a day results in a risk of heart disease that is halfway between that of a smoker and a non-smoker. The non-linear dose response relationship is explained by smoking's effect on platelet aggregation.

so ,I would like to give some advice photo to all who still smoking





so,smoking made your lung become bad and could made you become old and could burn all over the world......so, we should smoke less and less
