Prince Harry, 22, the third in line for the British throne has now vowed to quit smoking in the New Year, ahead of a sweeping Army ban, the Daily Mail reported on Tuesday.
He has smoked up to 20 Marlboro Lights a day ever since, even though his year-long army training course at Sandhurst, according to the report.
Cadets at the Royal Military Academy are not allowed to smoke inside the college but are permitted to do so in their free time.
Harry had earlier insisted that his smoking habit did not interfere with his health of fitness. But he has finally made a New Year's resolution to give it upfor good.
His decision comes as the Ministry of Defence prepares to ban smoking at all army barracks from March this year. Harry wants to cut down gradually before the new regulations come in, according to reports.
His decision is likely toheartenhis father, Prince Charles, who loathes his son's nicotine habit.
Prince Charles' wife, Camilla, the Duchess of Cornwall, was herself a heavy smoker, but is believed to have given it up in recent years.
However, unfortunately for Harry, whose girlfriend, Chelsy Davy is asocial smoker, giving up the smoking habit could be a little harder.
