"Breathing second hand marijuana smoke can be just as dangerous, and toxic, as smoking the actual joint. This is due to the chemicals and tar within the marijuana. Also, some marijuana has been coated with unknown substances by the supplier. Since the product is not regulated by the government, you don't know what you are buying, smoking or breathing.Marijuana lingers in the air for quite some
. time, especially in closed spaces. There is no filter on a joint, unlike a cigarette. Second hand smoke should be considered harmful to anyone who is exposed to it. Not only can you catch a second-hand buzz, or high, but you are exposing your lungs to chemicals that will coat the delicate tissues within your airway. Small exposure, such as catching a whiff of second hand marijuana smoke while outdoors, probably will not cause problems. Repeated exposure to the drug or spending lots of time around others who smoke pot can harm you. Breathing second hand marijuana smoke should be considered just as dangerous and harmful as breathing second hand cigarette smoke, and with the same long term consequences."
