Health effects of cannabis

The health effects of cannabis depend on the person using it, the type of cannabis used and the method of use (i.e. inhalation vs. ingestion). If you choose to use cannabis, it is important to be aware of the associated health risks:

  • At any age, cannabis use affects brain function, including impacts on attention, memory and learning. The brain does not stop developing until around age 25. The younger you are when you begin cannabis use, the more you ingest, and the longer you are a user, the bigger the impact on your brain.
  • You should not use cannabis if you have a predisposition or family history of psychosis or substance use disorder.
  • Cannabis can be addictive.
  • Toxic materials and contaminants can be absorbed into your lungs.
  • Overdosing can lead to nausea, anxiety and paranoia
  • Cannabis use impairs cognitive and motor functioning, making it unsafe to operate a motor vehicle or heavy machinery while impaired.
