Part 1: All of the cannabis health warning messages in this Part apply to cannabis products of all classes of cannabis listed in Schedule 4 to the Cannabis Act, with the exception of cannabis topicals.

  • WARNING: The smoke from cannabis is harmful. Toxic and carcinogenic chemicals found in tobacco smoke such as polyaromatic hydrocarbons, aromatic amines, and N-heterocyclics are also found in cannabis smoke.
  • WARNING: Do not use if pregnant or breastfeeding. Substances in cannabis are transferred from the mother to child and can harm your baby.
  • WARNING: Do not drive or operate heavy equipment after using cannabis. Cannabis can cause drowsiness and impair your ability to concentrate and make quick decisions.
  • WARNING: Frequent and prolonged use of cannabis containing THC can contribute to mental health problems over time. Daily or near-daily use increases the risk of dependence and may bring on or worsen disorders related to anxiety and depression.
  • WARNING: Adolescents and young adults are at greater risk of harms from cannabis. Daily or near-daily use over a prolonged period of time can harm brain development and function.
  • WARNING: The higher the THC content of a product, the more likely you are to experience adverse effects and greater levels of impairment. THC can cause anxiety and impair memory and concentration.
  • WARNING: It can take up to 4 hours to feel the full effects from eating or drinking cannabis. Consuming more within this time period can result in adverse effects that may require medical attention.
  • WARNING: The effects from eating or drinking cannabis can be long-lasting. The effects can last between 6 and 12 hours following use.

Part 2: The cannabis health warning message in this Part applies only to cannabis products that are cannabis topicals.

  • WARNING: Do not swallow or apply internally or to broken, irritated or itching skin. There may be health effects and risks associated with cannabis topicals that are not fully known or understood.
