Young smoker London - Arabstoday People who start smoking in their mid teens are at greater risk of developing potentially fatal smoking-related diseases than those who start a decade later, according to a study presented in Rome on Tuesday. \'Generation in smoke, strategies for not starting, tools for stopping\' compiled by the association I-think of centre-left Senator and transplant surgeon Ignazio Marino shows that 15.9% of boys and 21.8% of girls in the 15-24 age group smoke and that around 87% of smokers have their first cigarette before they reach 20. A person who starts smoking aged 15 \"is three times more likely to die of cancer than someone who starts ten years later\" according to the study. \"The life of a regular smoker is around 10 years shorter than that of a non-smoker and daily cigarette consumption (by young smokers) is similar to that of an adult,\" said Marino. Each year in Italy around 70,000 people die from smoking-related diseases, with a cost to the national health service of around 7 billion euros in 2011, or 7% of the overall budget.
