From the main page:
Over 1.2 billion people smoke daily, nearly a quarter of the worlds entire population. It is estimated that every cigarette smoked shortens your life span by approx. 14 minutes. The sad part is that nearly 6,000 teens start smoking each and every day. All of this translates to just under 5 million smoking related deaths each year with close to 14,000 people dying every day.
Some facts about smoking:
- Smokers have a death rate three times higher than non-smokers at all ages starting from young adulthood.
- On average, smokers who begin smoking in adolescence and continue to smoke regularly have a 50% chance of dying from tobacco use. Half of these will die in middle age, losing around 20-25 years of normal life expectancy.
- Globally, approximately 48% of men and 12% of women smoke.
- Smoking kills more people than alcohol, AIDS, car crashes, illegal drugs, murders, and suicides combined -- and thousands more die from other tobacco-related causes -- such as fires caused by smoking (more than 1,000 deaths/year nationwide) and smokeless tobacco use.
- 60mg of pure nicotine placed on a person's tongue would kill within minutes.
About 5% - 8% of each cigarettes output is smoke, the rest is comprised of invisible gasses such as:
- formaldehyde: used for embalming dead bodies - has a metallic taste
- ammonia: used for cleaning toilets - taste and smell like cat urine
- acetone: used to remove nail varnish
- carbon monoxide - emitted from car exhausts
- arsenic: used to kill rats
- hydrogen
- cyanide: used in gas chambers
- benzene: used as a petrol additive
- methanol
- wood alcohol acetylene: used as fuel in torches
- polonium 210: radioactive element. One study showed that a person who smokes 20 cigarettes a day receives a dose of radiation each year equivalent to about 200 chest x-rays
- lead: highly toxic metal, capable of causing serious damage to the brain, kidneys, nervous system and red blood cells
- vinyl chloride: a manufactured substance used to make polyvinyl chloride (PVC)

Still considering taking up the habit, give your head a shake!
With all the above information being widely available everywhere, why is it that people still smoke? Should education on smoking and drug use begin in school?
