If you are in the military, the odds are good that you light up.

Listen:

Capt. Lee Mandel is in the medical corps of the Navy. He says about 31-percent of our G.I.'s smoke, compared to about 20-percent of the general public. He says there are lots of reasons for the smoking increase in the military. One of them is peer pressure...but that pressure is older than you might think.

Mandel says World War 1 was the first time cigarettes were mass produced, and that meant soldiers, sailors, and marines would all have easy access to tobacco. Now Mandel says instead of adding it to the K-rations given to G.I.'s by the government, there are more smoking restrictions, removing some of the heavy discounts that military members get.

Mandel says he would like to see cigarettes off the shelves in military stores, cutting down on the instances of lung and heart disease as the ranks age.
