Yet another reason to quit smoking: TB

Okay, if you've got a running list, get it out and add this to your reasons to quit smoking: smoking has been linked to an increased risk for catching and developing tuberculosis.

Researchers at the University of California, Berkeley, compiled data from 24 previous studies on the subject and came up with some scary numbers. Smokers are 73% more likely to become infected with TB when exposed, and then more than twice as likely to develop the active form of the disease.

TB is no laughing matter (not to say that lung cancer or emphysema are either), but now that smoking has been pinpointed as a risk factor education and policies can be modified to hopefully help with prevention.
