Cigarettes contain about 600 ingredients. When they burn, they generate more than 7,000 chemicals, according to the American Lung Association. Many of those chemicals are poisonous and at least 69 of them can cause cancer.
“‘While we were aware that smoking is a risk factor for respiratory disease, cancer, and cardiovascular disease, this study shows it also has a detrimental effect on cognitive aging and this is evident as early as 45 years,’ said Severine Sabia of University College London, who led the study and published it in the Archives of General Psychiatry Journal.
Smoking harms nearly every organ of the body. Smoking causes many diseases and reduces the health of smokers in general.
Smoking causes death
• The adverse health effects from cigarette smoking account for an estimated 443,000 deaths, or nearly one of every five deaths, each year in the United States and cost the country a staggering $130 billion in health care costs and lost productivity.
• More deaths are caused each year by tobacco use than by all deaths from human immunodeficiency virus (HIV), illegal drug use, alcohol use, motor vehicle injuries, suicides, and murders combined.
• Smoking causes an estimated 90% of all lung cancer deaths in men and 80% of all lung cancer deaths in women.
• An estimated 90% of all deaths from chronic obstructive lung disease are caused by smoking.
