NextLineIsMine Reviewed by NextLineIsMine on . Running and Lungs Hey everybody. Well ive been running for the past 8 months id say in order to get into better shape. Now i also smoke alot of weed and sometimes cigarettes. I was just wonderin if the runnin helps clear my lungs up (i think it does) or if it is like bad for the lungs. Also i was wonderin if weed deposits tar and such in your lungs like tobaccao does. Thanks, later Rating: 5
