Cannabis Info

  • Why is it unsafe for youth to consume cannabis?

    The brain continues developing until around age 25, and the use of cannabis may interfere with this development.  This is because when consumed, cannabis directly interacts with your brain and central nervous system.  Risks are increased with heavy, prolonged consumption and the early onset of use. Learn more about cannabis effects here.

  • How long will cannabis stay in my system?

    This always depends on how much you consume, how you consume it and your genetics, age, personality, gender and other personal biological factors. Effects can take up to 24 hours to fully dissipate, but THC can be detectable in the bloodstream for up to seven days or more, depending on several factors, including frequency of use. There are few reports of secondary intoxication (i.e. from second hand smoke or vape), but it also depends on a number of factors, including dose and ventilation of the space.

  • What effects might I typically expect from cannabis strains with moderate THC levels?

    Cannabis directly interacts with the brain and central nervous system. THC generally produces an intoxicating or impairing effect, even when very little is consumed. In moderate consumption, effects may include a sense of relaxation and pleasant euphoria. THC can also cause unpleasant or harmful effects. Senses may be heightened. The effects vary from person to person and will further depend on strain, consumption method and personal factors like genetics, existing mental health conditions, current mood, age, personality and gender. 

  • Is recreational cannabis different than medical cannabis?

    In Ontario, recreational cannabis is only legally sold through the OCS, and medical cannabis is only available legally with a medical document from a physician or nurse practitioner through licensed sellers and Health Canada-approved at-home cultivation (click here for more information on accessing medical cannabis). Products available in both channels may be different at any given time due to different distribution channels, but both are grown under regulated, quality-controlled conditions.

  • Do all cannabis products make you “high”?

    No. Cannabis products containing THC will have an intoxicating effect or produce a “high”. However, some cannabis products are exclusively CBD and generally have no intoxicating effects.

  • Can I cook with cannabis?

    Yes, but it takes practice to create cannabis-infused products that are consistently dosed. You can learn more about the considerations of cooking with cannabis here. For information on safe food handling and preparation (i.e. cannabis-infused foods) please click here.

  • How do I know how much cannabis to consume?

    Always start with a very small amount: one inhalation or a very small amount ingested. Wait at least 10 minutes before inhaling again and 60 minutes before ingesting any more. If ingesting capsules or oil, please follow the directions on the packaging. If you’re new to ingesting cannabis, consider ingesting very small amounts and waiting at least an hour to determine a product’s full effect. The effects of cannabis vary from person to person and will also depend on the type of product and method used for consumption, along with other personal factors that can include genetics, existing mental health conditions, current mood, age, personality, gender and whether cannabis has been consumed often enough to develop a tolerance. If you’re new to consuming cannabis or looking for a milder psychoactive effect, choose products with lower THC potency or cannabis products that contain CBD. If you prefer to avoid any potential for intoxication, opt for 100% CBD products.

  • What Is CBD?

    CBD is short for cannabidiol and is another common cannabinoid in cannabis. When consumed, CBD affects various processes in your body but does not produce an intoxicating effect.

  • What Is THC?

    Short for tetrahydrocannabinol, THC is the most common cannabinoid in cannabis. It is the primary psychoactive cannabinoid responsible for the intoxicating “high” that may be experienced when it’s consumed.

Cannabis Health & Safety

  • Can I give cannabis to a minor in my home?

    No. According to the Cannabis Act, even parents or guardians can face significant legal consequences for distributing cannabis to a minor, including up to a 14-year prison penalty. The rules and penalties for distributing cannabis to minors are different than those set for alcohol distribution to minors.

  • How can I reduce the risks of consuming cannabis?

    Cannabis use has health risks that are best avoided by not using it. However, there are steps that can be taken that will reduce the health risks associated with use: Delay cannabis use until later in life (after the age of 25) Avoid using synthetic cannabis (e.g., K2, Spice)  Avoid use of cannabis before operating a vehicle, and wait at least six hours after using cannabis before operating a vehicle Avoid mixing cannabis with alcohol or tobacco Avoid smoking cannabis Limit and reduce how often you use cannabis  

  • Can I use cannabis while pregnant or breastfeeding?

    There is no known safe amount of cannabis to use during pregnancy or when breastfeeding. Cannabis use during pregnancy has been linked to low birth weight, and can harm a child’s brain development. Pregnant and breastfeeding women should not consume cannabis, as it could harm the fetus or baby.

  • Does cannabis consumption lead to other drug use?

    There is limited evidence that suggests cannabis use is likely to precede the use of other legal and illicit substances and the development of addiction to other substances. The majority of people who consume cannabis do not go on to use other harder substances, such as stimulants or opioids.

  • Is it unhealthy to inhale cannabis smoke?

    Inhaling smoke of any kind can lead to lung damage and respiratory problems. Certain smoking practices such as deep-inhalation or holding one’s breath increases these risks. It is known that cannabis smoke contains chemicals and tar that are similar to tobacco smoke.

  • Is it possible to overdose on cannabis?

    Consuming too much cannabis can result in significantly unpleasant effects, but they should be experienced temporarily. There is no documented case of death resulting from a toxic overdose of cannabis.

  • Are there programs to help me if I think I’ve become addicted?

    If you feel you have developed a cannabis-use disorder or addition, help is available.

  • Why shouldn’t alcohol be consumed with cannabis?

    Combining cannabis and alcohol can elevate the felt effects and lead to extreme intoxication, dizziness and nausea. Combining cannabis with alcohol can also increase the risk of vulnerable people experiencing psychotic symptoms. Combining the two further lowers concentration and reaction times.

  • Why shouldn’t tobacco be consumed with cannabis?

    Tobacco is harmful on its own, and the co-use of tobacco and cannabis has been associated with developing a dependence on either substance, negative mental health outcomes, engagement in other risk-taking behaviours, and increased difficulty stopping cannabis use. There is some evidence that suggests combining tobacco with cannabis can lead to smoking initiation as well. In addition, using both substances may also lead to increased health risks compared to using just one or the other, such as the impact on the respiratory system.

  • Can I drive while or after using cannabis?

    Driving while experiencing the psychoactive and intoxicating effects of cannabis containing THC is extremely dangerous. Do not drive after using cannabis, and ensure you are informed about the driving laws in Ontario. Although the effects of intoxication from cannabis that contains THC may wear off, cannabis stays in your system for some time. It is recommended that individuals who use cannabis refrain from driving (or operating other machinery or mobility devices) for at least six hours after using cannabis. If tested, you could test positive for cannabis content in your body. There are strict penalties for driving and cannabis in Ontario. For more information please visit the Ministry of Transportation website here.  Also be aware that combining alcohol and cannabis can elevate the felt effects and cause severe impairment.

  • What are the mental health effects of cannabis use?

    In some people, cannabis use increases the risk of developing mental illnesses, such as psychosis or schizophrenia. Any cannabis use is associated with a 40% increased risk of psychosis. Consuming cannabis can produce effects that induce mild or temporary symptoms of anxiety, paranoia and delusional beliefs or cause more permanent mental impairment.Those who start using cannabis at a young age, use it daily, and have a family history of mental illness are at a greater risk. The effects and onset of these illnesses may also be worsened by using higher-strength cannabis products.Frequent cannabis use has also been associated with an increased risk of suicide, depression and anxiety disorders. Cannabis use may also exacerbate symptoms of existing mental health problems, though further research is required.

  • Can I get hurt consuming cannabis?

    There is no documented case of death resulting from a toxic overdose of cannabis. However, it is possible to “overconsume” cannabis, whereby short-term and long-term adverse effects can occur, especially if you consume large amounts. Short-term adverse effects may include confusion, fatigue and anxiety, panic, paranoia, elevated heart rate, and a significant impact to your ability to make decisions and react quickly. The potential long-term risks include harm to your memory, decision-making ability, concentration, intelligence and mental health harms. Inhaling cannabis long term may also lead to lung damage and infections.Driving or operating large machinery after consuming cannabis would present great risks to yourself and others. Remember that driving while impaired is against the law. It’s also crucial to keep all cannabis products stored safely to avoid consumption by children or pets.
