INTRODUCTION

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. The most common method of smoking today is through cigarettes, primarily industrially manufactured but also hand-rolled from loose tobacco and rolling paper. Tobacco smoking is today by far the most popular form of smoking and is practiced by over one billion people in the majority of all human societies.
Smoking-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 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. 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. Among the diseases that can be caused by smoking are vascular stenosis, lung cancer, heart attack and chronic obstructive pulmonary disease.

Smoking is a hard habit to break because tobacco contains nicotine, which is highly addictive. Like heroin or other addictive drugs, the body and mind quickly become so used to the nicotine in cigarettes that a person needs to have it just to feel normal. People start smoking for a variety of different reasons. Some think it looks cool. Others start because their family members or friends smoke. Statistics show that about 9 out of 10 tobacco user start before they're 18 years old. Most adults who started smoking in their teens never expected to become addicted. That's why people say it's just so much easier to not start smoking at all.
