Smoking is a practice where a substance, usually tobacco or cannabis,
burned and the smoke tastes or inhaled. This is mainly practiced as a
route 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 part of the ritual, cause ecstasy and
spiritual enlightenment.
Cigarette smoking is one of the most common forms of recreational drug use, including through industrial manufacturing, and hand-rolled from loose tobacco and rolling papers. Other tools include smoking pipes, cigars, hookahs, vaporizers and bongs. It has been suggested that smoking-related disease kills half of all long term smokers, but these diseases can also be contracted by non-smokers. Last 4 years report states that approximately 4.9 million people worldwide die each year as a result of smoking. Smoking is one of the most common forms of recreational drug use.

At least half of smokers die
prematurely because of smoking life. The risk of dying
from lung cancer before age 80 is 22% for male
smokers and 12% in female smokers, in the absence
of competing causes of death. Similar calculations
for lifelong non-smoker is a 1.1% probability of dying
from lung cancer before age 80 for a man of European
origin, and a probability of 0.9% by a cigarette woman.
Smoking one day lead to a risk of heart disease which
is halfway between a
smoker and non-smokers. The non-linear dose-response
relationship is explained by the effect of smoking on platelet
aggregation.
Among the diseases caused by smoking are vascular stenosis, lung cancer, heart attack and chronic obstructive pulmonary disease.
Smoking is a risk factor for Alzheimer's disease. Although smoking over 15 cigarettes per day has been shown to exacerbate symptoms of Crohn's disease, smoking has been shown to effectively reduce the incidence of ulcerative colitis.
