Russian Roulette is safer and quicker.
One in four, eh?
Whatever.
According to your link,
During the 25 years, there were 2,900 deaths in the study group [of 8000 men and women]. Of those deaths, 109 were directly attributable to COPD, and nearly all those deaths were in people who were active smokers at the start of the study. Only two non-smokers died of COPD.
So, 109 COPD deaths out of 8000 people. How does that equate to Russian Roulette?
Smoking is a leading cause of lung cancer, but that is not the only form of this disease that has been linked to this habit. If a person smokes tobacco, they are also increasing their risk for other cancers, such as:
•Mouth
•Oesophagus
•Throat
•Tongue
•Voice Box
In addition to these cancers, smoking can also increase a person’s risk of developing the following types of cancer:
•Anus
•Bladder
•Cervix
•Kidney
•Liver
•Pancreas
•Penis
•Stomach
•Vulva
