weedporndaily: Smoking Marijuana Is Good For Your Lungs [Recent Study] (Inquisitr) Another big victory for marijuana supporters this week after a study was published in the Journal of the American Medical Association which found that smoking a moderate amount of pot can actually help your lung capacity. Researchers at University of California-San Francisco and University of Alabama at Birmingham examined 5,000 people ages 18 to 30 over a 20 year period and then collected information about each persons tobacco and marijuana smoking habits. Researchers then took measurements of a users lung capacity, specifically forced expiratory volume (FEV) which measures how much volume of air the lungs can hold along with forced vital capacity (FVC), or the speed at which a person can blow air out) at several key points during the studies entire period. Researchers as expected found that tobacco smoking reduced lung capacity while marijuana smoking in moderate marijuana smokers improved lung capacity for both FVC and FEV levels.  However the authors note that very heavy marijuana smoking still appears to decrease lung capacity.
