'Social smoking' as dangerous as daily habit
Smoking the odd cigarette when out with friends may seem relatively harmless, but a new study suggests it can be as dangerous as an everyday habit.
US researchers found that the risk of high blood pressure and worrying cholesterol was the same for all types of smoker.
More than 10 pc of the 39,000 people surveyed said they were 'social smokers' compared with 17pc who said they smoked daily.
The study found that around 75pc of both groups had high blood pressure, while 54pc had high cholesterol.
"Not smoking at all is the best way to go," said lead author Dr Kate Gawlik at Ohio State University.
