Smoking tobacco is a habit that has been around for about 2,000 years. It is one of the most common forms of recreational drug use. Smoking is practiced by more than a billion people in the world and it has gained more popularity recently.
Passive smoking is when a person that does not smoke comes in contact with smoke and it can be considered a health hazard that has caused many anti-tobacco campaigns to fight for non-smoking public areas.
The negative health effects of smoking have been the cause of many diseases like lung cancer, heart disease, and diabetes.
