33 Smoking a marijuana cigarette deposits about three to five times more tar into the lungs than one filtered tobacco cigarette.34 Consequently, regular marijuana smokers suffer from many of the same health problems as tobacco smokers, such as chronic coughing and wheezing, chest colds, and chronic bronchitis.35 In fact, studies show that smoking three to four joints per day causes at least as much harm to the respiratory system as smoking a full pack of cigarettes every day..
Damn...... I gotta rethink sum stuff! Is it really that bad compared to smoking?
