Legalizing and Strickly Regulating Cannabis - The Facts

The proposed Cannabis Act would create a strict legal framework for controlling the production, distribution, sale and possession of cannabis across Canada. The Act seeks to:

  • restrict youth access to cannabis
  • protect young people from promotion or enticements to use cannabis
  • deter and reduce criminal activity by imposing serious criminal penalties for those breaking the law, especially those who import, export or provide cannabis to youth
  • protect public health through strict product safety and quality requirements
  • reduce the burden on the criminal justice system
  • provide for the legal production of cannabis to reduce illegal activities
  • allow adults to possess and access regulated, quality controlled legal cannabis
  • enhance public awareness of the health risks associated with cannabis

The current program for accessing cannabis for medical purposes would continue under the new Act. Cannabis would remain illegal as the bill moves through the legislative process. If it is approved by Parliament, the bill could become law with a target date of no later than July 2018.

Restricted access

The Cannabis Act proposes many rules that would protect youth from accessing cannabis.

Protecting Youth

No person could sell or provide cannabis to any person under the age of 18. In addition, the Act would create 2 new criminal offences, with maximum penalties of 14 years in jail, for:

  • giving or selling cannabis to youth, and
  • using a youth to commit a cannabis-related offence

In order to prevent youth from using cannabis, the Act would also prohibit:

  • products that are appealing to youth
  • packaging or labelling cannabis in a way that makes it appealing to youth
  • selling cannabis through self-service displays or vending machines
  • promoting cannabis, except in narrow circumstances where the promotion could not be seen by a young person

Penalties for violating these prohibitions include a fine up to $5 million or 3 years in jail. The Government has also committed close to $46 million over the next five years for cannabis public education and awareness activities to inform Canadians, especially youth, of the health and safety risks of cannabis consumption.

Controlled Access

Should the Cannabis Act become law in July 2018, adults who are 18 years or older would be able to legally:

  • possess up to 30 grams of legal dried cannabis or equivalent in non-dried form
  • share up to 30 grams of legal cannabis with other adults
  • purchase dried or fresh cannabis and cannabis oil from a provincially-licensed retailer
    • In those provinces that have not yet or choose not to put in place a regulated retail framework, individuals would be able to purchase cannabis online from a federally-licensed producer.
  • grow up to 4 cannabis plants per residence for personal use from licensed seed or seedlings
  • make cannabis products, such as food and drinks, at home provided that organic solvents are not used

The sale of cannabis edible products and concentrates would be authorized no later than 12 months following the coming into force of the proposed legislation.

Strict Regulation

The federal, provincial and territorial governments would share responsibility for overseeing the new system. The federal government’s responsibilities would be to:

  • set strict requirements for producers who grow and manufacture cannabis
  • set industry-wide rules and standards, including:
    • the types of cannabis products that will be allowed for sale
    • packaging and labelling requirements for products
    • standardized serving sizes and potency
    • prohibiting the use of certain ingredients
    • good production practices
    • tracking of cannabis from seed to sale to prevent diversion to the illicit market
    • restrictions on promotional activities

The provinces and territories would license and oversee the distribution and sale of cannabis, subject to federal conditions. They could also:

  • increase the minimum age in their province or territory (but not lower it)
  • lower the personal possession limit in their jurisdiction
  • create additional rules for growing cannabis at home, such as lowering the number of plants per residence
  • restrict where adults can consume cannabis, such as in public or in vehicles

Criminal Penalties

The Cannabis Act proposes offences targeting those acting outside the legal framework, such as those involved in organized crime. Penalties would be set in proportion to the seriousness of the offence. Sanctions would range from warnings and tickets for minor offences to criminal prosecution and imprisonment for more serious offences.

Offence Penalties
Illegal distribution or sale
  • Tickets for small amounts
  • Up to 14 years in jail
Possession over the limit
  • Tickets for small amounts
  • Up to 5 years in jail
Production of cannabis beyond personal cultivation limits or with combustible solvents
  • Tickets for small amounts
  • Up to 14 years in jail
Taking cannabis across Canada’s borders
  • Up to 14 years in jail

Further penalties related to cannabis-impaired driving have been put forward in the proposed drug-impaired driving legislation. The proposed Cannabis Act is informed by the recommendations of the Task Force on Cannabis Legalization and Regulation.

Health Effects of Cannabis

There are both potential therapeutic uses for and potential health risks of using cannabis (marijuana). A chemical called delta-9-tetrahydrocannabinol (THC) is responsible for the way your brain and body respond to cannabis. While it is used by some for therapeutic purposes, there are short- and long-term physical and mental health effects that can be harmful.

SHORT-TERM HEALTH EFFECTS

While cannabis may make you feel relaxed and happy, you could experience unpleasant, unwanted or negative effects on your brain and body.

Effects on the brain

The short-term effects of cannabis on the brain can include:

  • confusion
  • sleepiness (fatigue)
  • impaired ability to:
    • remember
    • concentrate
    • pay attention
  • anxiety, fear or panic
  • reduced ability to react quickly

Cannabis use can also result in psychotic episodes characterized by:

  • paranoia
  • delusions
  • hallucinations

Emerging evidence suggests that a chemical in cannabis called cannabidiol (CBD) may help dampen some of the psychoactive effects of THC such as:

  • disturbances in mood
  • psychotic symptoms

There is also evidence to suggest that combining tobacco with cannabis can increase:

Effects can be felt within seconds to minutes of smoking, vaporizing or dabbing cannabis. These effects can last up to 6 hours or longer. If you eat or drink cannabis, these effects can occur within 30 minutes to 2 hours and can last up to 12 hours or longer.

Effects on the body

The short-term effects of cannabis on the body can include:

Impairment

The THC in cannabis can impair your ability to drive safely and operate equipment. It can also increase the risk of falls and other accidents. This is because THC can affect your:

  • coordination
  • reaction time
  • ability to pay attention
  • decision-making abilities
  • ability to judge distances

Cannabis use can increase the risk of accidents that lead to injury or death during higher-speed activities, such as driving, biking or skiing.

Impairment can last for more than 24 hours after cannabis use, well after other effects may have faded.

People who use cannabis regularly may have trouble with certain skills needed to drive safely for weeks after their last use. Combining alcohol with cannabis greatly increases the level of impairment and the risk of injury or death from accidents. Combining cannabis with other psychoactive substances, especially ones that have sedative effects, such as opioids and benzodiazepines, can increase the effects of the drugs. This could increase the risk of injury or harm, particularly with activities like driving.

LONG-TERM HEALTH EFFECTS

Long-term effects develop gradually over time with frequent use (daily or near-daily) that continues over weeks, months or years. These effects can last from several days to months or longer after you stop using cannabis.

Effects on the brain

The long-term effects of cannabis on the brain can include an increased risk of addiction and harm to your:

These effects appear to be worse for youth who start using early, and who use cannabis frequently and over a long period of time. They may not be fully reversible when cannabis use stops.

Effects on the body

Some of the long-term effects of smoking cannabis on the body are similar to the effects of smoking tobacco and can include risks to lung health, including:

  • bronchitis
  • lung infections
  • chronic (long-term) cough
  • increased mucus buildup in the throat

Potential therapeutic uses

There is some evidence of potential therapeutic uses of cannabis or its component chemicals (cannabinoids). Health Canada provides information for health care professionals and for authorized patients on the use of cannabis and cannabinoids for medical purposes. This includes information on dosing, adverse effects, warnings and more.

Risks of illegal cannabis

There may be other health and safety risks associated with cannabis obtained illegally. For example, the THC potency of illegal cannabis is often unknown, so you could end up using a stronger product than expected. This could heighten or prolong effects such as confusion or anxiety. The quality and purity of illegal cannabis cannot be guaranteed and is frequently mixed with or contains:

  • pesticides
  • other drugs
  • heavy metals
  • moulds or fungi
  • other contaminants

There is also the serious risk of:

  • interacting with criminals or criminal organizations
  • criminal charge and prosecution

Mental health effects

In some people, cannabis use increases the risk of developing mental illnesses like psychosis or schizophrenia, especially in those who:

  • start using cannabis at a young age
  • use cannabis frequently (daily or almost every day)
  • have a personal or family history of psychosis and/or schizophrenia

Frequent cannabis use has also been associated with an increased risk of:

  • suicide
  • depression
  • anxiety disorders

Health effects on youth

Cannabis use that begins early in adolescence, that is frequent and that continues over time has been associated with increased risk of harms. Some of those harms may not be fully reversible. Adolescence is a critical time for brain development, as research shows the brain is not fully developed until around age 25. Youth are especially vulnerable to the effects of cannabis on brain development and function. This is because THC in cannabis affects the same biological system in the brain that directs brain development. It is important for parents, teachers, coaches and other trusted adults to be ready to talk with youth about drugs.

Health effects on pregnancy and children

Just like with tobacco, a pregnant woman or new mother’s use of cannabis can affect her fetus or newborn child, which can lead to health problems. The toxins in cannabis are carried through the mother’s blood to her fetus during pregnancy and in the breast milk following birth. Heavy cannabis use during pregnancy can lead to lower birth weight of the baby. It has also been associated with longer-term developmental effects in children and adolescents, such as:

  • decreases in:
    • memory function
    • the ability to pay attention
    • reasoning and problem-solving skills
  • hyperactive behaviour
  • increased risk for future substance use

Addiction

Contrary to popular belief, people can become addicted to cannabis. Individuals who use cannabis can develop a cannabis use disorder, which at its extreme can result in addiction. Continued, frequent and heavy cannabis use can cause physical dependency and addiction. Research has shown that THC in cannabis causes an increase in levels of dopamine, the pleasure chemical, in the brain. This motivates people to keep using it. Addiction can develop at any age but youth are especially vulnerable as their brains are still developing. Some people are also more prone to becoming addicted than others. It’s estimated that 1 in 11 (9%) cannabis users will develop an addiction to it. This statistic rises to about 1 in 6 (17%) for people who started using cannabis as a teenager. If a person smokes cannabis daily, the risk of addiction is 25% to 50%. Problematic cannabis use can include some or all of the following behaviours:

  • failing to fulfill major duties at work, school or home
  • giving up important social, occupational or recreational activities because of cannabis use
  • consuming it often and in larger amounts or over a longer period than they intended
  • being unable to cut down on or control cannabis use

People who display most or all of these behaviours over a 12-month period may have cannabis addiction. Some people can develop a tolerance to the effects of cannabis. Tolerance is characterized by a need for a larger dose of a drug to maintain the original effects. Tolerance to some of the effects of cannabis can develop after a few doses. In some people, tolerance can eventually lead to physical dependence and/or addiction.
