Suing for cannabis impairment

Now that “recreational” use of cannabis is legal (Oct. 17/2018), many Canadians want to know what happens if they’re seriously injured by a cannabis-impaired driver.

“To the degree that legalization may increase the incidence of impaired driving, we’re likely to see more cases of cannabis impairment causing serious injuries,” says Todd Litwiniuk, a senior partner at the personal injury firm of Litwiniuk & Company in Calgary. “But legalization doesn’t change the issues at law relating to impaired driving.

“The key thing to remember is that under Canadian law, impaired driving is a criminal offence, regardless of the substance that causes impairment, or whether that substance is legal,” Litwiniuk says, “If you’re injured by a cannabis-impaired driver, your legal remedies are exactly the same as if that driver were impaired by alcohol.” It makes no difference whether cannabis was consumed recreationally or under prescription, he adds. “Medicinal use of cannabis was legalized in 2001 but driving while impaired by any prescription drug is still impaired driving and subject to the criminal penalties and civil liabilities prescribed by law.

“Let’s say you’re seriously injured after being T-boned by a cannabis-impaired driver at an intersection controlled by a traffic light. If you ran the red light, you’re very unlikely to have a case against the impaired driver — but the more likely scenario is that the impaired driver ran the light and is legally liable for your injuries.”

He says the major area of uncertainty in coming months will be how cannabis impairment is measured and proved in court. Federal law sets a cannabis impairment level of five nanograms of THC per millilitre of blood, which is legally equivalent to the long-established .08 blood-alcohol level. But cannabis has been proven to persist in the body much longer than alcohol. Litwiniuk says this is expected to open the door to legal challenges, with lawyers representing insurance companies arguing their insured drivers’ THC readings were the result of long-term use of cannabis rather than impairment at the time of the collision. That battle will most likely be fought first in criminal courts, with civil actions dependent to some degree on the outcome.

While a breathalyzer is used to test for blood alcohol levels, a legally-sanctioned breath-based test is not yet available for THC levels (though one is being developed). Saliva tests will be used to determine THC levels and, as with alcohol, these readings will be supported by an observation-based field sobriety test administered by police.

Once the science of THC testing is settled, Litwiniuk says, cannabis-related injury actions will be legally identical to other impairment law suits, and at this point, Albertans have a substantial advantage over residents of provinces with more extensive no-fault insurance regimes.

While many provinces have no-fault insurance systems that place tight limitations on court awards for serious injury claims, Alberta imposes fewer strictures. The Alberta regime includes no-fault provisions for auto damages and immediate medical needs not covered by provincial health services. This enables each driver’s own insurance company to pay immediate expenses without waiting for a finding of fault. For longer-term injuries involving pain and suffering, loss of income, personal expenses and costs of future care, Albertans have access to civil tort law — which is the ability to sue for damages.

The Supreme Court of Canada has placed a limit of approximately $380,000 (adjusted for inflation) on claims for pain and suffering and that limit applies Canada-wide, regardless of provincial law. Alberta has also placed a $4,000 ($5202 adjusted for inflation) cap on claims for strains, sprains and minor soft tissue injuries. But, while Alberta courts have been conservative in awarding compensation for pain and suffering, they have been willing to consider and make awards for damages not specifically regulated by federal or provincial statute. Those include costs of future care and treatment, lost wages and loss of housekeeping capacity, depending on the circumstances.

“It’s important to resist the offer of a quick settlement,” Litwiniuk advises. “Your injuries need to be completely healed or have reached long-term stability before any valid assessment of fair compensation can be made.” He says claimants should consult an experienced personal injury lawyer before signing off on any settlement. While the vast majority of personal injury claims are settled without going to trial, achieving a fair settlement, with or without a trial, is a process that takes time and benefits from experienced legal advice.

  • Cannabis impairment laws are unconstitutional

    James Tripp
    Medical Cannabis users can run at blood levels of 10 to 50 ng/ml of THC and even higher in some cases. This also ignores levels of CBD which have a major mitigating factor in the psychoactive effects of THC. Cannabis impairment laws will be unconstitutional and will be challenged in court due to the vast range of human tolerance to THC The daily use of Cannabis medicine most often results in a complete tolerance to the psychoactive effects of Delta 9 THC due to the receding of CB1 receptors in the central nervous system, specifically the brain, resulting in no impairment in the ability to operate a motor vehicle while using Cannabis medicine properly. I have gone from being a Sick, Angry, and often aggressive, driver due to illness, anxiety, depression, and constant pain, with no recourse but taking several pharmaceuticals; to a calm, attentive, relaxed, and aware driver due to the elimination of virtually all health issues and the need for pharmaceutical medications as well as all over the counter medications. As an abstainer from alcohol I am very disturbed that current legislation is proposing to punish drivers for the use of medicinal cannabis (5ngs or higher) because they seem to be under a brutally false impression that this blood level of THC is equal to the same impairment as THC combined with alcohol. This kind of attitude is patently absurd from a perspective of one who has used cannabinoid therapy daily to function normally for well over a decade. This will end in a multitude of court cases due to the erroneous assumption that Delta-9 THC causes universal impairment in humans. The incoming Laws, both Federal and provincial, in regards to cannabis use, are not only unjust, they are immoral, unenforceable, AND unconstitutional; They are, in my personal opinion, a continued violation of the Human rights of all Canadian citizens. Cannabis impairment is so vastly different, (and non-consistent) from virtually every other type of drug impairment, including alcohol, that to compare them is actually kind of ridiculous. The range of impairment goes from Zero to totally impaired. One individual can have 50ng/ml and be perfectly coherent and functional and another can have 5ng/ml and be completely impaired. The identification and removal from the road, of drivers that are actually impaired by Cannabis use will not be easy but arbitrarily locking up cannabis patients is just going to punish innocent people even more and cost everyone a great deal in court challenges. I suspect there will also be court challenges on recreational use alone that will not go well for the government simply because the currently proposed laws on cannabis impairment are based on false science and false assumptions. James E Tripp. P.S. The increases in cannabinoids found in drivers of fatal crashes is a statistical indicator of increased usage in the overall population and there is no statistical INCREASE in fatal crashes due to Cannabis use.. The fact is that fatal crashes have DECREASED overall in states where cannabis has been legalized (I speculate due to the substitution of cannabis for Alcohol coupled with the fact that cannabis is far less of an detrimental impairment that Alcohol). Alcohol causes an individual to become over confident, aggressive, and uncoordinated whereas cannabis (when it does affect the individual) most often has the effect of making the individual more cautious and aware, more docile than aggressive, and does not affect coordination near to the degree of alcohol, as well cannabis does not have the same affect on individual human physiologies universally. FYI Conclusions. Both MMLs and dispensaries were associated with reductions in traffic fatalities, especially among those aged 25 to 44 years. State-specific analysis showed heterogeneity of the MML–traffic fatalities association, suggesting moderation by other local factors. These findings could influence policy decisions on the enactment or repealing of MMLs and how they are implemented.
