Marijuana smoke is the inhalation of smoke that comes from heating cannabis marijuana. This smoke typically arises from smoking marijuana as a joint or blunt, or through a pipe, bowl or vaporizer. Marijuana smoke contains nearly 500 chemicals and more tar than cigarettes but is considered much healthier than cigarettes and has caused zero deaths. The smoke that comes from marijuana contains THC and CBD, some of the medically beneficial cannabinoids found in marijuana. Marijuana smoke is also a bronchodilator, which helps to open the lungs and clear out dirt.
