(ORDO NEWS) — It has long been known that smoking is harmful to people. In a new study, scientists at Oxford University (UK) calculated that tobacco use increases the risk of developing 56 types of diseases.
Among them are several categories of cancer, diseases of the eyes, pancreas, liver, as well as diabetes, asthma and others.
The researchers compared those who had never tried smoking before and those who were regular smokers at some point in their lives.
The scientists also observed those who currently smoked and tested their risk of developing certain diseases.
Experts studied 85 different causes of death and 480 diseases. The team collected data from China‘s Kaduri Biobank.
From 2004 to 2008, over 512,000 adults took part in the study. Among the participants, about 74.3% of men and 3.2% of women were regular smokers at some point.
Compared to those who had never smoked before, regular smokers had a 10% higher risk of getting sick. The disease that had the most notable increased risk of 216% was laryngeal cancer.
But the good news is that for those who quit smoking before the onset of health complications, the threats have been reduced.
About a decade later, their risk of developing a fatal disease has reached the level of those who have never smoked.
More than 8 million people die from smoking every year. At the same time, 84 million tons of carbon dioxide enter the atmosphere, and 4.5 trillion cigarette filters pollute the environment.
