What is Cannabis?
Cannabis is a psychoactive drug that is used for medicinal or recreational purposes. It comes in many forms (leaves/flowers, oils, edibles, hash etc.). Cannabis can have various side effects, which include pleasant (e.g. relaxed, happy) and unpleasant feelings (e.g. psychosis, paranoia). The two main compounds in cannabis are: THC (tetrahydrocannabinol), which creates a sleepy and hungry feeling, and CBD (cannabidiol) which does not give individuals a high, but is used for medicinal purposes. Different strains of cannabis contain different concentrations/levels of THC and CBD depending on the intended use. Medicinal cannabis must be authorized by a health care professional. Recreational cannabis is used for enjoyment and became legal for purchase in Canada on October 17, 2018.
Cannabis Use in Canada
According to the National Cannabis Survey, 1.8 million Canadians ages 15 and older reported using cannabis on a daily or almost daily basis in the first quarter of 2019. Although this number has not changed significantly following legalization it is still concerning as regular cannabis use is associated with an increase in risk of addiction and mental health issues.
Despite the fact that regular cannabis has remained stable (pre- and post-legalization), weekly and occasional cannabis use has increased in Canada following legalization. This is important to note as it has been theorized that even acute use of cannabis may have a harmful impact on the respiratory system. At this point in time, however, this is unclear.
The National Cannabis Survey also found that 15% of cannabis users with a valid driver's license reported driving within two hours of consuming cannabis. This is concerning as cognitive and motor abilities required to drive safely are negatively affected for up to three hours after consuming cannabis. Cannabis use impairs judgement and slows reaction time putting individuals at a greater risk driving related injuries and fatalities.
According to the Canadian Cannabis Survey, Ontarians who reported cannabis use in the last three months increased from 14% in the first quarter of 2018 (pre-legalization) to 20% in the first quarter of 2019 (post-legalization). Ontario was the only province to see an increase but it is unclear why that is (potentially more people comfortable using and reporting?).
Looking at data from the Ontario Student Drug Use and Health Survey (2015), it was found that approximately 1 in 5 grade 7-12 students in Ontario reported using cannabis in the previous year. This is important to note as brain development is not complete until the age of 25 and consuming cannabis at an early age can impact neural development, and subsequently decision making, attention span, and the ability to learn new things.
Cannabis Use in Nipissing and Parry Sound Districts
According to the Canadian Community Health Survey 10.9% of individuals in our region reported using cannabis in the past year. To further this, the Local Community Cannabis Survey that was conducted by the North Bay Parry Sound District Health Unit, found that three-quarters of surveyed individuals reported using cannabis before age 19. As I mentioned previously, this is concerning as brain development is not complete until the age of 25 and even acute exposure can have a negative impact on individuals (e.g. attention, memory).
Health Promotion
Health promotion aims to address the broader conditions that influence our health (e.g. social and physical environment, personal coping skills). The Health Unit can support initiatives in your communities related to substance use including cannabis via a health promotion lens. For example, we can support community development work where individuals with lived experience or who are allies can get involved in promoting health thereby strengthening community action. This could be through awareness campaigns, events and advocacy work related to substance use (in this case specifically cannabis use).
Through health promotion initiatives we also aim to build knowledge and skills of community members and partners through workshops and trainings (e.g. importance of delaying use, health impacts etc.).
In addition, we can help support the development of policies which improve health and create supportive environments (e.g. smoke-free beaches). Our goal is to provide a comprehensive approach to health issues including cannabis use.
Overview of Current Legislation
The Cannabis Act (2018) is the regulatory framework set out by the federal government with respect to legal cannabis use in Canada. The Act states that:
- the minimum age to consume cannabis in Canada is 18 years of age (can be increased by provincial government).
- four plants can be cultivated per household.
- individuals can possess 30g of cannabis on them for personal use.
The Cannabis Act also contains information related to production, distribution and sale of cannabis in Canada. In addition, it outlines restrictions on advertising and promotion to youth. Criminal penalties associated with breaking law and import/export as well as distributing cannabis to youth are also included. The Act further outlines strict quality and safety requirements around cannabis.
With the onset of legalization came changes to the Criminal Code of Canada. These included changes are related to the possession and trafficking of cannabis, and impaired driving offenses (i.e. how much THC you can have in your system while driving).
The Cannabis Control Act (2017) set out by the provincial government establishes restrictions related to the sale, distribution, purchase, possession, cultivation, propagation and harvesting of cannabis in order to protect public health and safety as well as protect and restrict access to youth. The Cannabis Control Act also deters illicit activities through appropriate enforcement and sanctions, and provides for approved educational programming that is culturally appropriate and used as an alternative to enforcement and sanctions.
Two other pieces of provincial legislation include the Ontario Cannabis Retail Corporation Act (2017) and the Cannabis License Act (2018) which relate specifically to requirements around retail outlets. The Alcohol Gaming Commission of Ontario (AGCO) will be speaking to these pieces of legislation later.
The goal of the Smoke-free Ontario Act (2017) is to protect Ontarians from physical and social exposure to second-hand smoke and vapour. The Act was updated on Oct 17, 2018 to include cannabis as well as a number of other changes. The Smoke-free Ontario Act now states that smoking and vaping of any substance including cannabis is no longer permitted wherever smoking tobacco is not permitted.
Previous to these changes the following locations were included in the Smoke-free Ontario Act (2017). These included:
- Indoor public places and workplaces
- Schools and where kids gather
- Hospitals and health care facilities
- Specific outdoor areas (20 m from playgrounds, sporting and spectator areas)
- On outdoor grounds of specified government office buildings
- Patios
New prohibited areas in the Smoke-free Ontario Act (2017) include:
- Public areas within 9 metres of any restaurant or bar patio.
- School property and public areas within 20 metres of the perimeter of the school grounds.
- The outdoor grounds of a community recreation facility, and public areas within 20 metres of the perimeter of the grounds (e.g., municipal community centres, hockey arenas, curling clubs).
Role of Municipalities
The legalization and subsequent inclusion of cannabis and e-cigarettes under the Smoke-free Ontario Act (2017) presents an opportunity for municipalities to open and expand their “No Smoking” by-laws to also include cannabis and vaping. It is also an ideal time to expand the number of smoke-free spaces where your residents and visitors gather, play and work under the by-law.
Many municipalities across Ontario now have by-laws that include these spaces.
Municipalities have a role to play when it comes to enforcement of cannabis use. Specifically, municipalities have the ability to enforce by-laws via their municipal by-law officers. Municipalities wishing to develop a cannabis by-law can outline fines associated with first as well as repeated offenses. Local public health units also play a role in enforcing those stipulations outlined in the Smoke-free Ontario Act (2017). I will touch on the role of public health units, specifically, Tobacco Control Inspectors in just a few moments.
Although municipalities cannot restrict the location of cannabis retail outlets through zoning or any other by-laws they can provide input and feedback to the Alcohol Gaming Commission of Ontario (AGCO) when a retail location is proposed. Municipalities may wish to develop a policy to help guide the review of new potential cannabis retail outlets. Some considerations for this policy may be to include:
- Density of Cannabis Retail Outlets: An increase density means an increase in access and potential harm. Outline minimum distances between stores (e.g. City of Calgary enacted 300m separation distance between cannabis stores).
- Density of Cannabis and Alcohol/Tobacco Retail Outlets: Discourage co-use of cannabis and other substances (e.g. alcohol) by enacting minimum distances between outlets (e.g. KFL&A Public Health recommends a 200m separation distance between cannabis and alcohol/tobacco retail outlets).
- Proximity to Sensitive Locations: Prevent role modeling of cannabis use through minimum distances of cannabis retail outlets to youth-serving facilities such as schools and community centres (e.g. The Centre of Addiction and Mental Health suggests 500m between cannabis retail outlets and sites such as schools and community centres).
Little is factually known about the effects of cannabis smoke on lung health. We do know that cannabis smoke irritates the throat and lungs, and contains toxins/carcinogens which can raise the risks for cancer and/or lung disease. At the moment, there is little data on the health risks associated with second-hand cannabis smoke and more research is needed. That being said, there is concern that it could have harmful effects on vulnerable populations like children and the elderly.
In addition, individuals exposed to second-hand cannabis smoke have tested positive in blood, urine and fluids for cannabis. This could prove problematic for some individuals (i.e. drug testing for work, impaired driving).
The consumption (i.e. smoking) of cannabis in public could normalize cannabis in the community. Normalization refers to something becoming a ‘normal part’ of life and is no longer considered potentially harmful. Knowing that children tend to copy what they observe and that normalization of substances can reduce age of initiation, the ability for individuals to smoke cannabis in public poses a significant issue to the health of populations (specifically children and youth). To further this, the normalization of cannabis could pose the risk of renormalizing all forms of smoking (including tobacco). This would be a step backwards for public health. As such, having municipalities develop a cannabis by-law can play an important part in the health and safety of individuals and communities.
Individuals who use cannabis can experience a wide range of symptoms including distorted perception (sights, sounds), loss of motor coordination, trouble with thinking and problem solving, impaired judgement, slow reaction time and drowsiness. Consumption of cannabis in public settings such as beaches, for example, could potentially increase the risk of accidents and/or fatalities (i.e. drowning, impaired driving).
Because cannabis has only been legal for a very short period of time we need to turn to other substances and jurisdictions to look at the potential impacts it might have on populations. With respect to alcohol, we know that it is a signification risk factor for drownings across Canada. Given that alcohol causes impairment and impacts decision making skills, judgement and coordination this is not surprising. Cannabis can impact individuals similarly meaning that smoking cannabis on beaches could potentially put individuals at a greater risk for drowning. We know that the Nipissing and Parry Sound Districts have a significant number of lakes so it is of definite importance that by-laws are developed to prohibit cannabis use in areas such as beaches (not just from a second-hand smoke impact but an individual safety point of view as well).
Looking to the United States, we can look to impaired driving statistics and cannabis use. At this point in time, findings (pre-/post-legalization) are mixed (i.e. whether legalization increased DUIs). That being said, we do know that from 2017 to 2018 the Colorado State Patrol noted:
- A 25 per cent increase in marijuana DUI citations.
- A 112 per cent increase in DUI citations involving both marijuana and alcohol.
- In 2018, more than 20 per cent of all DUI citations by CPS involved marijuana.
*Substance is based on trained trooper perception and may not reflect results from toxicology tests.
Despite these numbers being significant, it is unclear if legalization has actually caused an increased in impaired driving (with cannabis). Enhanced detection/training could also be playing a role in this. In addition, while some states have shown an increase in impaired driving following the legalization of cannabis others have shown a spike and then decrease or a decrease only. It is important to note that the data available is all we have at the moment to understand the potential impacts of cannabis and DUIs (increase/decrease). More time is needed to understand what impact legalization may have on local populations. What we do know is that greater access to substances results in increased consumption, which can lead to significant health and social harms/costs so there is the potential for legalization to have a negative impact on driving behaviour.
