In addition to its effects on the brain, marijuana has other health effects. Marijuana can damage your lungs. Marijuana smoke has many of the same chemicals as tobacco smoke, which are not healthy for lungs. People who smoke marijuana daily or near-daily may have a daily cough, bronchitis, mucus and wheezing. Marijuana smoke contains the same cancer-causing chemicals as tobacco smoke. Heavy marijuana smoking is strongly associated with tissue damage in the airways of your lungs.

Marijuana can also affect athletic performance and coordination. THC can interfere with reaction time and how someone experiences time and space. Using marijuana in any form will likely impair a teen’s ability to drive, play sports, or do other activities they enjoy.
