"Smoking a joint once a week or a bit more apparently doesn't harm the lungs, suggests a 20-year study that bolsters evidence that marijuana doesn't do the kind of damage tobacco does. The results, from one of the largest and longest studies on the health effects of marijuana, are hazier for heavy users -- those who smoke two or more joints daily for several years." (01/11/12)
