P1 Although marijuana is used as a remedy for some serious diseases, many studies show that it has many negative effects on the body. When marijuana is smoked, the dangerous chemicals rapidly pass from the lungs into the bloodstream. The bloodstream carries them to the brain and other organs throughout the body. Four of the most affected organs are the lungs, brain, reproductive system and heart. P2 There is enough evidence that marijuana increases the risk of lung cancer and infection. It also affects the lungs’ ability to bring in oxygen and get rid of carbon dioxide and germs. So Marijuana smokers are often at higher risk of developing breathing difficulties, chronic cough and chest pain.
