Stephanie Lake and Michael Milloy: Now that cannabis is legal, let’s use it to tackle the opioid crisis

The legalization of cannabis for adult use in Canada is one of the biggest national public policy shifts that many of us will witness.

This historic change in drug policy was proposed by the Canadian government as a way to promote public health, as the country grapples with some of the highest cannabis consumption rates in the developed world, including among adolescents.

Meanwhile, Canada is struggling to contain an entirely different substance-related problem: The opioid overdose epidemic.

Fuelled by the contamination of the illicit drug supply with fentanyl and its analogues, the opioid epidemic is Canada’s gravest public health crisis since the emergence of HIV in the 1980s. Experts agree on the need for creative responses based on scientific evidence.

Increasingly, scientists from the fields of public health, medicine and economics are aiming to figure out if cannabis legalization could be part of the solution.

The possibilities are multiple — from the use of cannabis to treat chronic pain to the potential of cannabis to reduce opioid cravings.

We recently published a new study showing that highly marginalized patients on “opioid agonist therapy,” with the drugs methadone or suboxone, were more likely remain on their treatment six months later if they were using cannabis on a daily basis.

Almost one in five Canadians live with some form of chronic pain. In the 1990s, pharmaceutical companies began to develop slow-release formulations of opioids (e.g. OxyContin) and marketed them as safe and effective medications for the treatment of chronic non-cancer pain. Opioids are now known to carry a high risk of dependence and overdose and yet more than 20 million opioid prescriptions are still filled each year in Canada.

Cannabis, derived from the Cannabis sativa plant, contains several compounds, including tetrahydrocannabinol (THC, the primary psychoactive component of cannabis) and cannabidiol (CBD). Beyond the well-known psychoactive effects of cannabinoids, research shows that they also interact with systems in the body involved in the regulation of pain.

This discovery has led researchers to investigate the potential for cannabis to treat various pain conditions for which opioids are currently first- or second-line therapies.

Although high-quality clinical research involving cannabis has been stunted by its prohibited legal status and the quality of the experimental studies in question ranges from low to moderate, recent extensive reviews of experimental research on cannabinoids for chronic non-cancer pain generally agree that they offer modest relief of pain.

This begs the question: if cannabis becomes more available, do people switch from opioids to cannabis?

In a landmark 2014 study, a team of researchers analyzed data from across the U.S. over a 10-year period. They found that states with legalized medical cannabis saw 25 per cent fewer opioid-related deaths than states where medical cannabis remained illegal.

These findings broke ground for others in the field to find associations between U.S. medical cannabis laws and reduced state-level estimates of opioid prescriptions, misuse and dependence, as well as opioid-related hospitalizations and non-fatal overdoses.

Opioid overdose trends have also changed in the aftermath of recreational cannabis legalization in some U.S. states. For example, a recent study found that opioid-related deaths in Colorado were reduced (albeit modestly) relative to two comparison states in the short term following recreational cannabis legalization.

Although it’s tempting to conclude that increasing access to cannabis is an effective intervention against the opioid crisis, there are several reasons to be cautious when interpreting these study findings.

First, not all cannabis laws are created equal. For example, Colorado and Washington followed a commercialized approach to cannabis legalization with fewer restrictions around things like marketing and product sales compared to Canada’s public health framework. These regulations are likely to impact the ways in which people access and use cannabis products, which could create different shifts in other substance use trends.

Indeed, a study led by leading drug policy economists in the U.S. found that the passage of a medical cannabis law on its own was not associated with changes in opioid-related outcomes. Only after the authors accounted for access to cannabis through legal provisions for retail dispensaries did they find a 25-per-cent reduction in opioid-related deaths.

Second — and this is the subject of ongoing discussion among substance-use researchers — these population-level studies are limited by their inability to observe individual-level changes in cannabinoid and opioid use.

As a result, it’s impossible to conclude whether it was actually the change in law that created these shifts in opioid outcomes. To better understand this, we need to take a closer look at different sub-populations of opioid users.

Findings from surveys with medical cannabis users across North America demonstrate a clear preference for cannabis over opioids.

However, two recent high-impact studies challenge our understanding of this complex topic. A four-year study of Australians on opioid therapy for chronic pain did not find significant reductions in use of prescribed opioids or severity of pain among cannabis users.

More research is needed.

But what about the relationship between cannabis and opioids among some of those most affected by the opioid crisis — people with long-term experience using illicit opioids?

Untreated pain and substance use have a high degree of overlap. Pain was reported by almost half of people who inject drugs surveyed in a recent San Francisco study. Research from our colleagues in Vancouver found that under-treatment of pain in this population is common and results in self-management of pain using heroin or diverted prescription opioids, which is becoming increasingly more dangerous.

There is growing evidence for the use of cannabis in treating opioid addiction. CBD, the non-psychoactive component of cannabis, is known to interact with several receptors involved in regulating fear and anxiety-related behaviours. It shows potential for the treatment of several anxiety disorders.

Research is also investigating CBD’s role in modulating cravings and relapses — behaviours linked to anxiety — among individuals with opioid addiction. Recent preliminary studies suggest that CBD reduces opioid cravings. Our own research suggests that patients are more likely to stay in opioid agonist therapy during periods of intensive cannabis use.

The opioid overdose crisis is so dire in some regions that community harm reduction groups, like the High Hopes Foundation in Vancouver’s Downtown Eastside, are starting cannabis-based substitution programs that provide free access to cannabis products for drug users.

Canada is the first G-20 country to introduce a legal framework regulating the use of cannabis by adults. Legalizing cannabis will break down historic barriers to understanding its clinical and public health impacts. Canada should harness this opportunity to understand if, and how, cannabis legalization could fit into a multi-faceted opioid prevention and response strategy.

Harm reduction is a set of practical strategies and ideas aimed at reducing negative consequences associated with drug use. Obviously, complete abstinence is the most effective way to reduce drug-caused harm. The next best way is harm reduction. The best thing to compare it to is practicing safe sex – no sex prevents all harm, but safe sex significantly reduces STDs and unplanned pregnancy. Harm reduction works the same way. Many people are not willing or are not ready to stop using drugs. The safer they are while using drugs, the less disease, infection, and deaths will occur.

Harm reduction can be applied to every substance. There is always a safer way to use substances, whether they be alcohol, opioids, prescription drugs, crack, meth, or ecstasy. The most commonly known harm reduction is opioid and intravenous drug use harm reduction. This is because needle exchanges are becoming much more popular around the world including the United States. This is because needle exchanges are one of the most effective ways to prevent HIV/AIDS. According to the ACLU, more than a quarter of all Americans with HIV directly contracted the illness from intravenous drug use. Also, needle exchange programs have reduced HIV infections by one-third to two-fifths nationwide, so it is no surprise that their acceptance and popularity is increasing.
