Safer cannabis use

If you choose to use cannabis, learn about how to use it safely, to reduce the chance of having a bad experience.

Cannabis comes from the hemp plant Cannabis Sativa and can be brown, grey or green in colour. The two main chemicals found in cannabis are delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD).

THC is the chemical ingredient that gives the plant its mind-altering effects. CBD is the chemical ingredient that does not produce psychoactive effects, but may offer therapeutic benefits.

Whether cannabis is inhaled or ingested, it eventually enters the blood stream, brain and other organs, which is when an individual begins to feel “high”. The high may cause euphoria/relaxation, laughing, increased appetite and increased heart rate.

Forms and effects of cannabis

Smoking of dried cannabis through joints, spliffs, blunts, bongs or pipes causes an immediate onset of effects that last a few hours. Smoking of any substance, including cannabis, causes harm to lungs.

  • Onset: Seconds
  • Duration: 1 – 5 hours

Vaping of concentrates or juices may be less harmful to lungs but only with reputable cartridges.

  • Onset: Seconds
  • Duration: 1 – 3 hours

Dabbing of waxes, shatter or other concentrates has extremely high amounts of THC and can cause immediate negative effects for those with low tolerance.

  • Onset: Instant
  • Duration: 1 – 3 hours

Eating of cannabis-infused items or edibles takes much longer to onset (up to two hours) and lasts much longer. Edibles will not be regulated until 2019.

  • Onset: 15 minutes – 2 hours
  • Duration: 4 – 6 hours

Topical application onto sore joints or muscles in the form of oils, creams or lotions causes an effect within 20 to 30 minutes and can last around 12 hours.

  • Onset: 20 – 30 minutes
  • Duration: 12 hours

Medical cannabis

Cannabis is used for medical purposes in order to treat or relieve chronic diseases, ailments, or conditions rather than for recreational or spiritual purposes.

Medical cannabis has been prescribed to:

  • Relieve nausea/vomiting associated with chemotherapy
  • Help with poor appetite and weight loss associated with illnesses such as cancer and HIV/AIDS.
  • Provide relief from chronic pain.
  • Treat muscle spasms associated with MS.
  • Help with treatment-resistant epilepsy in children.

How to lower your risk

Think about not using cannabis: If you’re under 21, have a history of psychosis, are pregnant or use cannabis as your main method to deal with stress, you should consider not using cannabis.

Occasional use lowers risk: If you choose to use, try to limit use to only on weekends or one day a week.

Lower risk products: Products with high THC may cause more harm. CBD can counteract some of the adverse effects of THC. This means that products with high CBD to THC ratios reduce some of the risks.

Wait six hours before driving: Cannabis can impair your motor coordination, judgement and other driving skills. The recommendation is to wait at least six hours before driving.

One substance at a time: Combining cannabis use with other substances, such as alcohol or prescription drugs, may cause stronger and more unpredictable reactions.

Natural products: Compared with natural products, synthetic cannabis products (K2, Spice) can have unpredictable and in some cases, life-threatening effects.

Smart smoking practices: Taking shallow puffs reduces toxins in the lungs. 95% of the THC in smoke is absorbed in the first few seconds, so there is no need to puff hard or hold your breath.

Reduce exposure to smoke: Cannabis smoke contains tar and toxins that can be harmful to lungs. Vaporizers or edibles reduce the risk to lungs. If you are going to consume edibles, take small amounts or wait at least an hour before taking more.

What to do if you have a bad experience

If you consume too much cannabis, a higher potency than you are used to, or combine cannabis with other drugs, you may experience nausea and/or vomiting, or react with panic, anxiety or paranoia.

If you experience some of these symptoms:

  • find a safe place and sit down,
  • try to relax,
  • talk to someone you trust to remain grounded,
  • hydrate and eat a snack,
  • take a hot shower,
  • remember the effects are temporary, and
  • get medical attention if symptoms are severe.
