1. Executive Summary

A. Background and Methodology

The safety and security of Canadians is a priority for the Government of Canada. Drug-impaired driving is a major contributor to fatal road crashes, and young people continue to be the largest group of drivers who die in crashes and test positive for drugs. To address this, Public Safety Canada developed a national marketing and multi-media advertising campaign in 2017 to inform Canadians, particularly youth aged 16 to 24, about the dangers and risks associated with drug-impaired driving. The campaign includes partnerships with key stakeholders (MADD, CAA, CACP, and Young Drivers of Canada), public communications and outreach, and paid media (advertising).

Objectives of the Study

The purpose of the research is to examine current knowledge, attitudes, and behaviours related to the dangers and risks, as well as legal implications of drug-impaired driving, compared with the initial baseline measured in 2017. A key focus is on youth and parents of youth, given that youth are the primary target audience for the campaign. Specifically, the research measures:

The results will help to guide future communications activities, and highlight changes that have occurred among the target group and broader Canadian public since the start of the campaign in 2017.

Methodology

The survey is comprised of 2,024 completed cases, including 401 with youth who are 16 to 24, and 404 parents of youth (16 to 24). This randomly recruited probability sample carries with it a margin of error of +/-2.18%. The margin of error for each of the target groups is +/-4.9%. The sample source is an in-house Probit panel of randomly recruited Canadians. Ten percent of the sample was collected with cell phone only sample. Fifteen percent were collected by trained, bilingual interviewers, while the majority were collected through online self-administration. Appendix A presents further methodological details of the survey.

B. Key Findings

Behaviour

The large majority of Canadians (84%) know someone who has used cannabis and three in five (60%) have consumed cannabis at some point in their lives (both indicators are a slight increase of 81% and 56%, respectively, in 2017). Of respondents who reported cannabis use, nearly three in five (58%; a notable increase from 39% in 2017) reported they are a recent cannabis user, having consumed it within in the past 12 months.

Consistent with 2017 results, over one-quarter (26%) of cannabis users reported they have operated a vehicle while under the influence. Nearly one in three Canadians also report that they have ridden in a vehicle operated by a driver who was under the effects of cannabis.

More than one in three (38%) parents of children ages 13 to 24 reported that their child has used cannabis. Most parents (81%) said their 16 to 24 year old has not driven a vehicle while under the influence of cannabis. Nearly six in ten, 58%, believe that their 13 to 24 year old has not accepted a ride with a driver under the influence of cannabis, although 33% are unsure. Eight in ten parents say they have had discussions with their 16 to 24 year old about driving high, although only 32% of young people 16 to 24 report the same.

Awareness and Concern for Risks

Most Canadians perceive the detrimental impact of impairment on drivers, with an increasing understanding that cannabis affects one’s ability to drive. Nearly nine in ten (86%; an increase from 81% in 2017) agree that using cannabis impairs one's driving ability. Four in five say that cannabis impacts reaction time and ability to concentrate and nearly two in three (66%) say that cannabis makes the user a worse driver. Alcohol remains a greater concern, however, with 94% agreeing that drinking alcohol impairs driving. Nearly one in four (23%) continue to say that driving under the influence of cannabis is less dangerous than driving under the influence of alcohol.

Half (49%) of Canadians perceive that the rate of driving while under the influence of cannabis has increased since legalization, and most are concerned (46%) or moderately concerned (29%) about others on the road who are driving under the influence of cannabis. The most pressing concerns over driving under the influence include hurting someone else (70%), generally getting into an accident (46%), or having a permanent criminal record (38%; an increase from 29% in 2017).

Normalized Behaviour

More than eight in ten Canadians (83%) believe it is not acceptable for people you know to drive high and only 6% say it is acceptable. On the other hand, Canadians are split on the variation in social acceptability of driving impaired compared with alcohol, with 42% saying it is more socially acceptable to drive under the influence of cannabis than alcohol and a further 10% saying they do not know.

Similar to 2017, over half of respondents reported that it is rare for people they know to drive under the influence, although 14% said it is common. Over one in three (37%) say they would be comfortable in reporting someone driving under the influence of cannabis to the police.

Information about Cannabis-impaired Driving

The incidence of searching for information on the effects of drugs on driving ability remains relatively low, with just three in ten respondents saying they have searched for this information. By a wide margin, health professionals are the most trusted source of information on the impacts of cannabis on driving ability, selected by more than half of respondents (58%), followed by law enforcement (30%).

Two in three Canadians are interested in learning more about the effects of cannabis on driving ability, followed by the length of time before it is safe to drive after using drugs. Canadians are also interested in learning about the effects of different forms of cannabis consumption (54%; not asked in 2017). Less than half (44%) would also like more information about how the police test for drugs or about the laws and penalties regarding driving while impaired (44%). Over one-third are interested in learning about their rights as a driver should they be pulled over.

Views on Legal Status and Implications

Nine in ten (91%) Canadians recognize that it is illegal to operate a vehicle while under the influence, up from 83% in 2017. Four percent continue to believe it to be legal, but fewer Canadians are unsure (five percent) than in 2017 (11%).

Some Canadians are unsure about the amount of time a driver should wait before getting behind the wheel after consuming cannabis before it is safe to operate a vehicle. In fact, one-third said they "don’t know" (34%, although less than the 43% reported in 2017). A full 44% believe it requires three or more hours (up to a full night of sleep), which has increased from 31% found in 2017. Nonetheless, the same proportion as in 2017 still believe that less than three hours is needed (14%; 15% in 2017).

Numbers have risen in terms of Canadians’ awareness that police can detect impairment from cannabis among drivers stopped at the roadside. Nearly two in three (63%) believe that police are capable of determining whether a driver is impaired from cannabis, an increase from 45% in 2017.

Awareness of drug-impaired driving legal penalties is moderate with over one in four (27%) Canadians saying they are aware that penalties for driving while impaired from cannabis can include a fine, loss of licence, or imprisonment and criminal record. Another 32% say they are somewhat aware, although 40% report a lack of awareness. One in five (19%) Canadians feel they are aware of general laws around cannabis and the legal consequences of breaking those laws, and a further 36% report they are somewhat aware.

Two in three (65%) Canadians believe that impairment from cannabis and impairment from alcohol carry the same penalties, an increase from just under half (47%) in 2017. One-quarter say they do not know.

Less than half of Canadians (43%) believe that penalties are strict enough to prevent people from driving under the influence of cannabis, although this is higher among young people 16 to 24 (55%).

C. Note to Readers

Detailed findings are presented in the sections that follow. Overall results are presented in the main portion of the narrative and are typically supported by graphic or tabular presentation of results. Bulleted text is also used to point out any statistically and substantively significant differences between sub-groups of respondents. If differences are not noted in the report, it can be assumed that they are either not statistically significant[1] in their variation from the overall result or that the difference was deemed to be substantively too small to be noteworthy. The programmed survey instrument can be found in Appendix A.

It should be noted that the survey asks a numbers of questions about behaviours that may have a tendency to exert social desirability pressure for respondents to underreport their use of cannabis as well as incidence of driving while impaired, for themselves and their teens/young adults[2]. The primary purpose of the survey is to provide a baseline against which future changes in awareness, knowledge, attitudes, beliefs and behaviours can be subsequently measured.

Results for the proportion of respondents in the sample who either said "don’t know" or did not provide a response are not indicated in the graphic representation of the results in all cases, particularly where they are not sizable (e.g., ten% or greater). Results may also not total to 100% due to rounding.

2. Detailed Findings

A. Reported Behaviour

Cannabis Use within Social Networks

A strong majority of Canadians know someone who has used cannabis, which is consistent with 2017 findings. More than eight in ten (84%; 81% in 2017) said that someone close to them has consumed cannabis at some point in their lives. Just 11% do not believe they are closely acquainted with a cannabis user and five percent are uncertain.

Recent Cannabis Use

Of those who reported cannabis use, 58% indicated they have used cannabis within in the past 12 months, which is a sizable increase from 39% saying the same in 2017 findings. Crossing overall use with recent use, results indicate that 35% of Canadians have used cannabis in the last 12 months, up 13% from 2017. It is interesting to note, however, that the increase is largely in past cannabis users becoming recent users (last 12 months) since there is not a significant increase in those who have ever tried it, although up from 56% to 60%.

Sources for Cannabis

In a new question in 2020, one-third (31%) of Canadians who have used cannabis in the past 12 months said they typically acquire it from a legal storefront. Fewer than one in five said they buy from a legal online source (17%) or from a friend (15%). Fewer than one in ten reported obtaining cannabis through shared experiences with friends (eight percent), a dealer (six percent), their own plants (six percent), family members (five percent) or an acquaintance (three percent). Only three percent of respondents said they obtained cannabis from either an illegal storefront or an illegal online source.

Influences on Sources for Obtaining Cannabis

The consideration that is most likely to influence the decision of where to obtain cannabis, according to 38% of respondents, is quality and safety of the product. Fewer than one in five (15%) reported pricing to be a main driver, and a similar number (13%) base their decision on the legality of the source. About one in ten are driven by convenience (nine percent) and the availability of specifics products such as edibles (seven percent).

Parents’ Perceptions of Use among Youth

More than one in three (38%) parents of young people 13 to 24 indicated their child has used cannabis, up from 34% in 2017. Compared with the self-reported use by youth aged 16-19 (44%), parents of 16 to 19 year old children have a reasonably good assessment of cannabis use by their children (38% reported by this segment of parents). For youth aged 20-24, 70% self-reported cannabis use; however, 50% of parents of those 20 to 24 reported cannabis use by their child suggesting parents are considerably less aware of use by their young adult children.

Only eight percent reported that their child has ridden as a passenger with an impaired driver, although 33% of youth reported the same (higher among those ages 20-24 at 41%). The pattern was similar in 2017.

Discussions between Parents and Youth

Survey results highlight a large discrepancy between how parents and youth recall discussing driving while under the influence of cannabis. One-third of young people 16 to 24 (32%) report having discussed this matter with their parents, this is an increase from 2017 (25%). In a sharp contrast, however, eight in ten parents of young people 16 to 24 (80%) report they have had this discussion with their children, up slightly from 74% in 2017.

Fewer than one in five discussed the parallels with driving of cannabis and alcohol (13%, down from 21% in 2017), or strategies to avoid these situations (13%). Other topics include, for example, not accepting rides from impaired drivers (12%), the dangers and risks to oneself and others (9%).

B. Risks of Cannabis-Impaired Driving

Perceptions of Impairment from Alcohol and Cannabis Use on Drivers

According to results, Canadians have very little doubt that alcohol impairs one's driving skills. As in 2017, more than nine in ten respondents (94%; as in 2017) agree that alcohol impedes driving ability, and only five percent disagree. Survey results also highlight broad recognition of the impacts of cannabis on drivers. Nearly nine in ten (86%) agree that using cannabis impairs one's driving ability, which is higher than the 81% who agreed in 2017.

Nature of Impacts of Cannabis impairment on Driving Ability

Respondents were also asked to select – from a prompted list – the ways in which they believe cannabis consumption affects driving ability. Results show an increasing awareness of the effects of cannabis on driving. Eight in ten (80% compared to 74% in 2017) believe that cannabis reduces reaction time and ability to concentrate and nearly two in three (66%; an increase from 57% in 2017) also said that cannabis makes the user a worse driver. There remain some individuals who perceive that cannabis makes the user a more careful driver (seven percent, a marginal decrease from nine percent in 2017) and two percent say cannabis consumption has no discernible impact on driving ability (two percent in 2017).

Perceived Risk of Cannabis-impaired driving Compared with Alcohol

When asked whether cannabis consumption is less dangerous than alcohol on one's driving ability, two-thirds (66%) said they do not believe this to be the case. This is an increase from 62% in 2017, although a similar proportion as in 2017 (23%; 25% in 2017) still believe this to be true, and another 10% are unsure.

C. Concern for Impaired Driving

Top Road Safety Concerns

Respondents were asked about their top three concerns when it comes to driver safety. While distracted driving emerged as the single largest concern (75%), this is followed by impaired driving from either alcohol, cannabis or prescription drugs (63%), and aggressive driving (61%). Concerns related to impaired driving are somewhat less pervasive than they were in 2017 (compared with 67% in 2017), but not as much as the reduction in concern for distracted driving (down from 84% in 2017).

In the administration of the survey one-third of respondents were shown "driving while under the influence of alcohol", one-third were shown "driving while under the influence of cannabis" and one-third were shown the response using "prescription drugs". Results reveal that impairment from alcohol is still a far greater concern for most Canadians (with 74% placing this as a top three concern), followed by impairment from cannabis (44%) and prescription drugs (42%). In fact, when shown impairment from cannabis use in the list, aggressive driving becomes a much more likely second choice for concern (65%). These results have changed only marginally since 2017, following the same pattern.

Perceived Impact of Cannabis Legalization on Incidence of Impaired Driving

In a new question added in 2020, Canadians highlighted their belief that cannabis-impaired driving is on the rise since recreational use of cannabis became legal in Canada. In fact, half (49%) feel the incidence of driving while impaired from cannabis has increased (20% said a large increase and 29% said a "little" increase). Another 33% feel that the incidence remains the same as it was prior to legalization, however, virtually no one believes the rate has decreased.

Level of Concern Regarding Cannabis-Impaired Driving

In terms of concern about others on the road who are driving under the influence of cannabis, most report at least a moderate concern. Just under half (46%) indicated they are concerned or even very concerned, and another 29% said they are moderately concerned. Only one in four (25%) rated themselves as not very or not at all concerned.

Personal Concerns with Driving Impaired

When asked about their biggest concern if driving while under the influence of cannabis, hurting, paralyzing, or killing someone else was seen as the key concern, according to 70% of respondents. In a second tier of concern, 43% pointed to personally getting hurt, paralyzed or killed in an accident, and just generally getting into an accident is also a concern for almost half of respondents (46%). Although less of a concern than these top three, fully 38% said that having a permanent criminal record, possibly affecting employment or international travel is a concern, which is a considerable increase from 2017 at 29%. Another 22% pointed to getting caught by police as a concern, also an increase from 14% in 2017. Other concerns are limited including significantly increased insurance premiums, family or peer judgement, or damage to property.

Respondents were shown the list with getting hurt, paralyzed or killed in separate categories, with "getting killed" selected most often of the three (21%), followed by "getting hurt" (19%), and then "becoming paralyzed" (15%). Multiple responses were accepted, allowing respondents to select each of these in unison, if desired.

Likelihood of Accepting a Ride

When asked how likely they would be to accept a ride from someone they knew was under the influence of cannabis, more than eight in ten (82%) said they would not, which is a slight increase from 78% in 2017. Nine percent said they would be likely to do so and a further eight percent indicated a moderate likelihood, which is similar to results found in 2017.

Personal Concerns for Being a Passenger

Concerns as a passenger in a vehicle where the driver was under the influence of cannabis were also explored. As in 2017, the top concern is getting hurt, becoming paralyzed or getting killed in an accident (85%). Although still a key concern, fewer are worried about hurting, paralyzing, or killing someone else (55%). Again, as a passenger, getting caught by police (12%), or having a permanent record (10%) are of considerably less concern. Only five percent of respondents said they would be worried about damage to property and three percent indicated family or peer judgement. Results are generally very similar with those found in 2017.

As with the question related to being the driver, getting killed, hurt and becoming paralyzed were shown separately. As a passenger, results reveal significantly greater concern for getting hurt (68%) or killed (49%), whereas fewer are worried about becoming paralyzed (36%).

D. Normalized Behaviour

Social Acceptability of Driving Under the Influence

In terms of how acceptable it is for people they know to drive while under the influence of cannabis, a clear majority (83%) said they do not see it as acceptable, which is an increase from 79% in 2017. Only 10% see it as moderately acceptable and another six percent believe it is acceptable.

Results nonetheless highlight a split in perception about the relative social acceptability of driving while under the influence of cannabis compared with alcohol. Although half (48%) do not believe this to be true, 42% said they believe that it is more socially acceptable than driving with alcohol-induced impairment, and another 10% were unsure. These results mirror closely the findings in 2017.

E. Information

Incidence of Searching for Information

The incidence of searching for information on the effects of drugs on driving ability is moderate, which is consistent with 2017 results. Nearly three in ten respondents (29%) indicated they have searched for information, although over two-thirds (70%, a slight increase from 66% in 2017) have not.

Preferred Sources for Information

When asked about preferred sources for information on the impacts of drugs on driving ability, health professionals remain the most trusted source by a wide margin, selected by more than half of respondents (58%, 57% in 2017). Three in ten (30%) indicated law enforcement as a preferred source, which is similar if marginally decreased from 32% in 2017. One in seven (16%) would consult with a friend, and one in ten (10%) would turn to a teacher, counsellor, or social worker. Other sources were selected much less frequently.

Respondents were also asked to specify which online sources they would consult for information about the effects of drugs on driving ability. Two-fifths (42%, a decrease of five percentage points from 2017) cited the Internet in general, with no mention of a specific organization. The most frequently cited specific source, however, is a Government of Canada website, according to 38%[3], an increase from 31% in 2017. Nearly one in four said they would turn to a police organization (24%), the Canadian Automobile Association (23%, down six percent from 2017), or a not-for-profit group such as Mothers Against Drunk Driving Canada (23%). One in five pointed to a website maintained by their provincial or municipal government (20%, an increase from 17% in 2017).

Type of Information Sought

Respondents were similarly asked to identify the types of information they would want to know about the effects and risks of drug use on driving ability. Two-thirds (66%, a decrease from 74% in 2017) indicated an interest in learning more about the effects of cannabis on driving ability, or the length of time before it is safe to drive after using drugs (62%). Over half of respondents (54%) want to know the effects of different forms of cannabis (not included in the list shown in 2017). Just under half (44%; down from 56% in 2017) would like more information about how the police test for drugs and a similar number (44%; down from 50%) want to learn more about the laws and penalties regarding driving while impaired. Nearly two-fifths (38%; up from 34% in 2017) are interested in learning about their rights as a driver should they be pulled over, while one in five (19%) would like advice on how to talk with family members about drug use.

Availability of Trusted Information Sources

As in 2017, respondents were asked whether they feel they have enough trustworthy information about the effects of drugs on driving ability in order to make informed decisions about risk. Half of respondents in the survey sample were asked generically about "information", while the other half were asked about "Canadian information" specifically.

Based on results, Canadians feel more informed in terms of availability of trustworthy information to make decisions than they did when surveyed in 2017. Half of respondents (50%) said they have enough information to make informed decision, an increase from 42% in 2017. Similar to 2017 findings, another third (33%) feel they have moderate access to information. One in ten (11%) do not feel they have sufficient information at their disposal, a decrease from 20% in 2017.

Canadians are similarly positive about the availability of Canadian information (i.e., from a Canadians content). Just under half (45%) said Canadian information is available, compared with 32% in 2017. One-third (31%, a slight decrease from 35% in 2017) indicated moderate availability, and fewer than one in five (15%, down from 23% in 2017) said that information is limited.

F. Cannabis Laws and Consequences

Familiarity with Current Legal Status

Canadians are generally aware that driving while under the influence of cannabis is not legal. Over nine in ten (91% compared to 83% in 2017) recognize that it is currently illegal to operate a vehicle while under the influence, however, one in twenty (five percent) still believe it to be legal and another five percent are uncertain.

Familiarity with Duration of Impairment

Based on results of the survey, Canadians are very unsure about the amount of time a driver should wait before getting behind the wheel after consuming cannabis before it is safe to operate a vehicle. In fact, more than one in three (34%) said they are uncertain. One in four (25%, compared to 18% in 2017) believe a user should wait three hours or more and slightly less (18%, an increase from 13% in 2017) feel it is best to drive only after a night of sleep. Although few believe that one to two hours (three percent) or two to three hours (eight percent) is sufficient.

Familiarity with Detection Technology

Results suggest an increasing awareness among Canadians about whether police can detect impairment from cannabis among drivers who are stopped at the roadside. In 2017, 45% of Canadians felt that police can detect impairment; this has increased to 63% in 2020. Over one in ten (14%) still believe police can not detect impairment at the roadside. The proportion of those unsure has also decreased, with 23% indicating they do not know, compared to 31% in 2017.

Legal Consequences of Driving Impairment: Cannabis versus Alcohol

When asked whether they believe the penalties associated with driving while impaired from cannabis are greater, lesser, or equivalent to those associated with driving while impaired from alcohol, the majority of Canadians believe that impairment from cannabis and impairment from alcohol carry the same penalties (65% believe penalties are the same, a sizable increase from 47% in 2017). Less than one in ten (six percent compared to 12% in 2017), however, believe that the penalties associated with cannabis are less strict that those regarding alcohol, and another four percent believe cannabis impairment carries greater consequences. A notable portion of Canadians are again unsure (25%, although a notable decrease from 35% in 2017).

A. Methodological Details

Sample Source

The survey sample was drawn from our randomly recruited panel Probit. Probit panellists were selected using a random-digit dial (RDD) landline-cell phone hybrid sample frame. This is the same sample frame and sampling process used to conduct telephone surveys, which are considered to be representative of the population[4]. Once selected, they are contacted and recruited by telephone and asked to complete a basic profile (i.e. base survey instrument) including a range of demographic information about themselves. They are also asked if they would prefer to complete surveys online or by telephone. All sample members are eligible to participate, including those with cell phones only, those with no Internet access and those who simply prefer to respond by telephone rather than online. This panel represents a fully representative sample of Canadians, from which we can draw random samples and collect data in a more cost conscious and timely manner than would otherwise be possible in a traditional telephone survey. This panel of more than 100,000 individuals can be considered representative of the general public in Canada (meaning that the incidence of a given target population within our panel very closely resembles the public at large) and margins of error can be applied.

Testing and Administration

Prior to conducting the survey, the instrument was tested with 12 cases in English and 19 cases in French. Additional questions were placed on the pretest version of the questionnaire asking about length, flow, clarity of wording and so on to elicit feedback from respondents. Minimal changes were made as a result of the testing, although a few questions were removed in order to stay within the intended survey length.

The survey was administered between January 21 and February 17, 2020, using a bilingual questionnaire, installed on a secure web-server controlled by Ekos. The email invitation included a description and purpose of the survey (in both languages) along with a link to the survey website. The survey database was mounted using a Personalized Identification Number (PIN), so only individuals with a PIN were allowed access to the survey (the PIN was included in the email invitation). The questionnaire was prefaced with a brief introduction to the study and rationale for the research. The voluntary and confidential nature of the survey was also emphasized. Survey data collection adhered to all applicable industry standards. All invited panel members were informed of their rights under current Privacy legislation, as well as how to obtain a copy of their response and results of the survey.

In this survey, a sample of 13,889 was drawn from the online only portion of the Probit panel, although over 6,800 were sent in an effort to target young people 16 to 24.

Another 1,002 panel sample members were contacted by telephone. This is a typical participation rate for this kind of survey. The response rate was 24% among those 25 years of age or older, and 12%[5] among young people 16 to 24. The average length of the interview was 17 minutes.

Respondents were informed in the invitation that all responses are completely confidential and no responses will be linked to individual names.

The database was reviewed following data collection for data quality, outliers, coding requirements, weighting and construction of independent variables, and was used to explore sub-group patterns (e.g., by age, gender and so on) in the analysis. Weighting of the sample was based on population parameters according to the latest Census on age, gender and region of the country.

Sample Characteristics

The following table presents a sample profile for the baseline survey. This includes demographic characteristics related to employment, education, income, cultural attributes, language, age and region. Each is presented for the full sample of 2,132 Canadians.

The sample over represents those with post secondary education, including 52% with a university level of education compared with 23% in the population, and under represents those with high school/elementary or college levels of education. This is partially driven by the oversample of younger Canadians. There are fewer Canadians born outside of Canada represented in the sample (12%) than found in the population (25%).
