Cannabis contains substances that affect the brain and body, including delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD).

The effects of cannabis on young people's health:
Cannabis affects the same biological system in the brain that is responsible for brain development.
Youth and young adults are more likely to experience harms from cannabis because their brains develop until about age 25. Starting as a teen, consuming frequently (daily or near daily) and over a long time (several months or years) increases the risk of mental health problems such as depression.
Everyone's response to cannabis can also differ from one time to the next. If you are using cannabis for medical purposes, deciding if cannabis is appropriate to treat your symptoms is best done in discussion with your health care provider.
