Alcohol, drugs different, drug-impaired driving a growing concern: panel

Alcohol and drugs are different and approaches to addressing related impairment issues will likely need to be different as well, Doug Beirness, senior research associate with the Canadian Centre on Substance Abuse (CCSA), suggested Wednesday during a State Farm-sponsored event in downtown Toronto.

“Everything that we go to do that tries to parallel alcohol will be different in many different ways. We need to take account of that and we need to work harder and find new solutions. Doing the research is one way to do that,” Beirness argued during the Drugs & Driving Expert Panel Discussion, which explored the issue of drug-impaired driving and its potential impact on road safety.

Following Prime Minister Justin Trudeau’s promise to legalize recreational use of marijuana, State Farm released a survey this past May on what Canadians think of the move and how it may influence road safety issues.

About six in 10 – 62% – of those taking part in the online poll – involving 3,000 respondents of driving age across Canada – said they believe the legal system is unprepared to deal with people who drive under the influence of marijuana.

In addition, 53% of those polled reported they do not think police have the necessary tools and resources to identify marijuana-impaired drivers, a State Farm press released noted at the time.

Survey findings further indicated almost six in 10 – 59% – of respondents reported thinking that impaired driving will increase if and when marijuana becomes legal.

“With the onset of medicinal and legal recreational use in Canada, we felt it was the right time to engage in public dialogue to shed light on this issue,” Tracey Pether of Pether Insurance & Financial Services Inc. and an insurance agent with State Farm, said before the panel discussion.

“We are not lobbying or supporting the legalization of or further criminalization of marijuana or drugs, prescription or otherwise,” Pether told attendees.

“Drug-impaired driving is a national discussion that requires government, non-profit organizations and Canadians to come together to shape our future. We’re trying to help facilitate a discussion and prevent injury and deaths of Canadian road users,” she added.

“When we look at drivers who have been killed in road crashes, we have seen increases in the presence of drugs,” reported panel member Robyn Robertson, president and CEO of the Traffic Injury Research Foundation (TIRF).

With regard to “the presence of marijuana in drivers killed in road crashes, we’ve seen an increase from about 13% to almost 20%,” Robertson said.

Research by TIRF indicates 28.5% of fatally injured drivers whose blood tested positive for marijuana in 2012 were between the ages of 16 and 34; 21.1% were 35 to 49; 10.6% were 50 to 64; and 1.3% were 65 or older.

“The bottom line is we are seeing it surpass alcohol in fatal crashes and that’s certainly an issue of concern,” Robertson emphasized.

Clint Stibbe, a traffic services media officer for Toronto Police Service, said drug-impaired driving is hardly a new issue, pointing out he arrested his first drug-impaired driver about 15 years ago.

That said, “it is becoming more mainstream and it’s something that I think is a challenge that we face,” Stibbe added. “But I think partners together we can beat this challenge and be successful in making the roads safer for everyone.”

Despite successes in seeing motor vehicle injury rates go down over the years, however, related injuries and deaths “still remain way too high,” argued Pamela Fuselli, vice president of knowledge transfer and stakeholder relations for the injury-prevention charity, Parachute.

“We know that effective ways to address it are known and if we can get those adopted, then we will start to see the injuries reduced to a more reasonable level,” Fuselli said.

“Over the last many years, it’s been alcohol that’s been the focus of our research,” Beirness of the CCSA pointed out.

“Over the last 10 or 12 years, it’s suddenly shifted to drugs, and recently, it’s been cannabis,” he added.

CCSA’s hope is to “expand the database, expand the amount of information we have on this topic so that we can inform policymakers and program developers so that we can better deal with this issue,” he told attendees.

However, a number of challenges remain, including how to test for impairment.

A recent CCSA study of cannabis and the impact on road safety presented a surprising result, Beirness said.

Looking at the THC – tetrahydrocannabinol, the psychoactive compound in marijuana – “level of those drivers, what you find is THC level makes no difference in terms of their level of impairment,” he reported. Individuals were “equally impaired on most measures that we looked at,” he said.

“Everybody wants to think that there’s a magic level out there somewhere that we can use,” something akin to the 0.08% blood alcohol concentration level used to indicate legal impairment.

“It’s not going to be that easy,” Beirness cautioned. One need only look to Colorado and Washington to see “what happens when you do open up the market to legal cannabis use,” he maintained.

Although there currently is no roadside test for cannabis, Stibbe acknowledged, there are sobriety tests that can be used in conjunction with subsequent assessments performed by police drug recognition experts.

The State Farm survey found that of those respondents who have driven high – about one in 10 – 44% said that it has no impact on their ability to drive safely; another 14% reported being unsure.

Information from CCSA notes the effects on driving of a number of types of drugs:

  • marijuana – slows reaction time, impairs short-term memory and concentration and causes driver to vary speed and to wander;
  • stimulants (such as cocaine and methamphetamine) – reduces driver balance and co-ordination, reduces impulse control and increase risk-taking;
  • opioids (such as oxycodone, heroine and fentanyl) – slows reaction time, reduces ability to divide attention and follow instructions and slows driving; and
  • sedatives (such as benzodiazepines, depressants and sleep medications) – impairs motor co-ordination and slows reaction time, and decreases attentiveness and ability to divide attention.

Asked what would make respondents stop driving high, 20% reported nothing would make them stop, four out of 10 reported stiffer penalties would deter them followed by more public awareness.

It is “an important time for us to sit and talk about the issue and ensure that we have the same set of knowledge and facts so we can have an informed discussion,” Robertson told those assembled for the event.

“That’s the most instrumental part to developing good programs, good policies and keeping roads safe,” she emphasized.

Fuselli said there are some concerning perceptions among young people about how dangerous alcohol is compared to marijuana.

“I think that there’s a misperception that there is a more increased risk and that when they are smoking marijuana they are not as impaired as they are when they are drinking alcohol,” she said.

Stibbe’s view was clear. “There’s no grey area when it comes to impairment. “Whether it’s alcohol or drug, impaired is impaired,” he emphasized.

“Governments are stepping up to change the laws that we have in place in order to adapt to the challenges that we see coming,” Stibbe commented.

That said, “the reality is that even with all of the laws that we have, it boils down to the individual taking responsibility for what they do when they get behind the wheel of that car,” he added.

Drug-impaired driving “has serious implications for drivers, passengers and pedestrians,” John Bordignon, media relations spokesperson for State Farm, told Canadian Underwriter.

“The clear costs associated with the drug-impaired driving issue are the number of lives that can be saved, injuries prevented and property damage curtailed by bringing more awareness to this issue,” Bordignon says.

“Legislation is imminent so we know legal recreational marijuana use is coming. As an insurance company we do not write legislation or create laws, but anything that helps to save lives, prevent injury and decrease property damage is good for everyone,” he adds.

    First off I think that the messaging regarding marijuana use and impaired driving are way off the mark. I would be very interested in the kind of studies that are happening, especially the test subjects in these studies. Of course someone that has not smoked or rarely uses marijuana will be impaired. People that use marijuana as medication for certain conditions on a daily basis will be substantially less impaired or will not be impaired at all.

    In regards to alcohol, those individuals that have higher tolerance will be less impaired by individuals that have less tolerance no matter their blood counts.

    Personally I have known many people that are on heavy pharmaceuticals that drive and are more likely to be impaired than any marijuana user.

    Lets face it, the best test to assess if someone is impaired would be a series of road side tests by the officers, rather than some inaccurate machine that does not measure tolerance. Everybody is different.

    Thanks for allowing me to respond.

  2. Tom Towers says:

    The assumption is that legalizing marijuana will increase its use, are we sure that will be the case?

  3. Zorba says:

    if you want so called value in this silliness let us start with the prescribed pills as well – studies exist that show improvement in driving results with weed – cops are overeacting due to losing their capricious powers with prohibition adying.
