  2. Smoking: The most common method of smoking today is through cigarettes, primarily industrially manufactured but also hand-rolled from loose tobacco and rolling paper. Other smoking implements include pipes, cigars, bides, hookahs, vaporizers and bongs. It has been suggested that smoking-related disease kills one half of all long term smokers but these diseases may also be contracted by non-smokers. A 2007 report states that about 4.9 million people worldwide each year die as a result of smoking.

  3. History: The history of smoking dates back to as early as 5000 BC in shamanistic rituals.[2] Many ancient civilizations, such as the Babylonians, Indians and Chinese, burnt incense as a part of religious rituals, as did the Israelites and the later Catholic and Orthodox Christian churches. Smoking in the Americas probably had its origins in the incense-burning ceremonies of shamans but was later adopted for pleasure, or as a social tool.[3] The smoking of tobacco, as well as various hallucinogenic drugs was used to achieve trances and to come into contact with the spirit world.

  4. Health effects: Among the diseases that can be caused by smoking are vascular stenosis, lung cancer heart attacksand chronic obstructive pulmonary disease. The effects of addiction on society vary considerably between different substances that can be smoked and the indirect social problems that they cause, in great part because of the differences in legislation and the enforcement of narcotics legislation around the world. Though nicotine is a highly addictive drug, its effects on cognition are not as intense or noticeable as other drugs such as, cocaine, amphetamines or any of the opiates (including heroin and morphine).
