BC Addictions Expert Questions Ties Between Safer Supply Advocates and For-Profit Companies

By Liam Hunt
Canada’s safer supply programs are “selling people down the river,” says a leading medical expert in British Columbia. Dr. Julian Somers, director of the Centre for Applied Research in Mental Health and Addiction at Simon Fraser University, says that despite the thin evidence in support of these experimental programs, the BC government has aggressively expanded them—and retaliated against dissenting researchers.
Somers also, controversially, raises questions about doctors and former health officials who appear to have gravitated toward businesses involved in these programs. He notes that these connections warrant closer scrutiny to ensure public policies remain free from undue industry influence.
Safer supply programs claim to reduce overdoses and deaths by distributing free addictive drugs—typically 8-milligram tablets of hydromorphone, an opioid as potent as heroin—to dissuade addicts from accessing riskier street substances. Yet, a growing number of doctors say these programs are deeply misguided—and widely defrauded.
Ultimately, Somers argues, safer supply is exacerbating the country’s addiction crisis.
Somers opposed safer supply at its inception and openly criticized its nationwide expansion in 2020. He believes these programs perpetuate drug use and societal disconnection and fail to encourage users to make the mental and social changes needed to beat addiction. Worse yet, the safer supply movement seems rife with double standards that devalue the lives of poorer drug users. While working professionals are provided generous supports that prioritize recovery, disadvantaged Canadians are given “ineffective yet profitable” interventions, such as safer supply, that “convey no expectation that stopping substance use or overcoming addiction is a desirable or important goal.”
To better understand addiction, Somers created the Inter-Ministry Evaluation Database (IMED) in 2004, which, for the first time in BC’s history, connected disparate information—i.e. hospitalizations, incarceration rates—about vulnerable populations.
Throughout its existence, health experts used IMED’s data to create dozens of research projects and papers. It allowed Somers to conduct a multi-million-dollar randomized control trial (the “Vancouver at Home” study) that showed that scattering vulnerable people into regular apartments throughout the city, rather than warehousing them in a few buildings, leads to better outcomes at no additional cost.
In early 2021, Somers presented recommendations drawn from his analysis of the IMED to several leading officials in the B.C. government. He says that these officials gave a frosty reception to his ideas, which prioritized employment, rehabilitation, and social integration over easy access to drugs. Shortly afterwards, the government ordered him to immediately and permanently delete the IMED’s ministerial data.
Somers describes the order as a “devastating act of retaliation” and says that losing access to the IMED effectively ended his career as a researcher. “My lab can no longer do the research we were doing,” he noted, adding that public funding now goes exclusively toward projects sympathetic to safer supply. The B.C. government has since denied that its order was politically motivated.
In early 2022, the government of Alberta commissioned a team of researchers, led by Somers, to investigate the evidence base behind safer supply. They found that there was no empirical proof that the experiment works, and that harm reduction researchers often advocated for safer supply within their studies even if their data did not support such recommendations.
Somers says that, after these findings were published, his team was subjected to a smear campaign that was partially organized by the British Columbia Centre on Substance Use (BCCSU), a powerful pro-safer supply research organization with close ties to the B.C. government. The BCCSU has been instrumental in the expansion of safer supply and has produced studies and protocols in support of it, sometimes at the behest of the provincial government.
Somers is also concerned about the connections between some of safer supply’s key proponents and for-profit drug companies.
He notes that the BCCSU’s founding executive director, Dr. Evan Wood, became Chief Medical Officer at Numinus Wellness, a publicly traded psychedelic company, in 2020. Similarly, Dr. Perry Kendall, who also served as a BCCSU executive director, went on to found Fair Price Pharma, a now-defunct for-profit company that specializes in providing pharmaceutical heroin to high-risk drug users, the following year.
While these connections are not necessarily unethical, they do raise important questions about whether there is enough industry regulation to minimize potential conflicts of interest, whether they be real or perceived.
The BCCSU was also recently criticized in an editorial by Canadian Affairs, which noted that the organization had received funding from companies such as Shoppers Drug Mart and Tilray (a cannabis company). The editorial argued that influential addiction research organizations should not receive drug industry funding and reported that Alberta founded its own counterpart to the BCCSU in August, known as the Canadian Centre of Recovery Excellence, which is legally prohibited from accepting such sponsorships.
Already, private interests are betting on the likely expansion of safer supply programs. For instance, Safe Supply Streaming Co., a publicly traded venture capital firm, has advertised to potential investors that B.C.’s safer supply system could create a multi-billion-dollar annual market.
Somers believes that Canada needs more transparency regarding how for-profit companies may be directly or indirectly influencing policy makers: “We need to know exactly, to the dollar, how much of [harm reduction researchers’] operating budget is flowing from industry sources.”

Four new studies show link between heavy cannabis use, serious health risks

New Canadian research shows a connection between heavy cannabis use and dementia, heart attacks, schizophrenia and even death
Six months ago, doctors in Boston began noticing a concerning trend: young patients were showing up in emergency rooms with atypical symptoms and being diagnosed with heart attacks.
“The link between them was that they were heavy cannabis users,” Dr. Ahmed Mahmoud, a cardiovascular researcher and physician in Boston, told Canadian Affairs in an interview.
These frontline observations mirror emerging evidence by Canadian researchers showing heavy cannabis use is associated with significant adverse health impacts, including heart attacks, schizophrenia and dementia.
Sources warn public health measures are not keeping pace with rapid changes to cannabis products as the market is commercialized.
“The irony of this moment is that society’s risk perception of cannabis is at an all-time low, at the exact moment that the substance is probably having increasingly negative health impacts,” said Dr. Daniel Myran, a physician and Canada Research Chair at the University of Ottawa. Myran was lead researcher on three new Canadian studies on cannabis’ negative health impacts.
Legalization
Canada was the first G7 country to create a commercial cannabis market when it legalized the production and sale of cannabis in 2018.
The drug is now widely used in Canada.
In the 2024 Canadian Cannabis Survey, an annual government survey of cannabis trends, 26 per cent of respondents said they used cannabis for non-medical purposes in the past year, up from 22 per cent in 2018. Among youth, that number was 41 per cent.
Health Canada’s website warns that cannabis use can lower blood pressure and raise heart rates, which can increase the risk of a heart attack. But the warnings on cannabis product labels vary. Some mention risks of anxiety or effects on memory and concentration, but make no mention of cardiovascular risks.
The annual cannabis survey also shows a significant percentage of Canadians remain unaware of cannabis’ health risks.
In the survey, only 70 per cent of respondents said they had enough reliable information to make informed decisions about cannabis use. And 50 per cent of respondents said they had not seen any education campaigns or public health messages about cannabis.
At the same time, researchers are finding mounting evidence that cannabis use is associated with health risks.
A 2023 study by researchers at the University of Calgary, the University of Alberta and Alberta Health Services found that adults with cannabis use disorder faced a 60 per cent higher risk of experiencing adverse cardiovascular events — including heart attacks. Cannabis use disorder is marked by the inability to stop using cannabis despite negative consequences, such as work, social, legal or health issues.
Between February and April of this year, three other Canadian studies linked frequent cannabis use to elevated risks of developing schizophrenia, dementia and mortality. These studies were primarily conducted by researchers at the Ottawa Hospital Research Institute and ICES uOttawa (formerly the Institute for Clinical Evaluative Sciences).
“These results suggest that individuals who require hospital-based care for a [cannabis use disorder] may be at increased risk of premature death,” said the study linking cannabis-related hospital visits with increased mortality rates.
The three 2024 studies all examined the impacts of severe cannabis use, suggesting more moderate users may face lower risks. The researchers also cautioned that their research shows a correlation between heavy cannabis use and adverse health effects, but does not establish causality.

Budtenders
Health experts say they are troubled by the widespread perception that cannabis is entirely benign.
“It has some benefits, it has some side effects,” said Mahmoud, the Boston cardiovascular researcher. “We need to raise awareness about the side effects as well as the benefits.”
Some also expressed concern that the commercialization of cannabis products in Canada has created a race to produce products with elevated levels of THC, the main psychoactive compound that produces a “high.”
THC levels have more than doubled since legalization, yet even products with high THC levels are marketed as harmless.
“The products that are on the market are evolving in ways that are concerning,” Myran said. “Higher THC products are associated with considerably more risk.”
Myran views cannabis decriminalization as a public health success, because it keeps young people out of the criminal justice system and reduces inequities faced by Indigenous and racialized groups.
“[But] I do not think that you need to create a commercial cannabis market or industry in order to achieve those public health benefits,” he said.
Since decriminalization, the provinces have taken different approaches to regulating cannabis. But even in provinces where governments control cannabis distribution, such as New Brunswick and Nova Scotia, products with high THC levels dominate retail shelves and online storefronts.
In Myran’s view, federal and provincial governments should instead be focused on curbing harmful use patterns, rather than promoting cannabis sales.
Ian Culbert, executive director of the Canadian Public Health Association, thinks governments’ financial interest in the cannabis industry creates a conflict of interest.
“[As with] all regulated substances, governments are addicted to the revenue they create,” he said. “But they also have a responsibility to safeguard the well-being of citizens.”
Culbert believes cannabis retailers should be required to educate customers about health risks — just as bartenders are required to undergo Smart Serve training and lottery corporations are required to mitigate risks of gambling addiction.
“Give ‘budtenders’ the training around potential health risks,” he said.
“While cannabis may not be the cause of some of these negative health events … it is the intersection at which an intervention can take place through the transaction of sales. So is there something we can do there that can change the trajectory of a person’s life?”

Study links B.C.’s drug policies to more overdoses, but researchers urge caution

By Alexandra Keeler
A study links B.C.’s safer supply and decriminalization to more opioid hospitalizations, but experts note its limitations
A new study says B.C.’s safer supply and decriminalization policies may have failed to reduce overdoses. Furthermore, the very policies designed to help drug users may have actually increased hospitalizations.
“Neither the safer opioid supply policy nor the decriminalization of drug possession appeared to mitigate the opioid crisis, and both were associated with an increase in opioid overdose hospitalizations,” the study says.
The study has sparked debate, with some pointing to it as proof that B.C.’s drug policies failed. Others have questioned the study’s methodology and conclusions.
“The question we want to know the answer to [but cannot] is how many opioid hospitalizations would have occurred had the policy not have been implemented,” said Michael Wallace, a biostatistician and associate professor at the University of Waterloo.
“We can never come up with truly definitive conclusions in cases such as this, no matter what data we have, short of being able to magically duplicate B.C.”
Jumping to conclusions
B.C.’s controversial safer supply policies provide drug users with prescription opioids as an alternative to toxic street drugs. Its decriminalization policy permitted drug users to possess otherwise illegal substances for personal use.
The peer-reviewed study was led by health economist Hai Nguyen and conducted by researchers from Memorial University in Newfoundland, the University of Manitoba and Weill Cornell Medicine, a medical school in New York City. It was published in the medical journal JAMA Health Forum on March 21.
The researchers used a statistical method to create a “synthetic” comparison group, since there is no ideal control group. The researchers then compared B.C. to other provinces to assess the impact of certain drug policies.
Examining data from 2016 to 2023, the study links B.C.’s safer supply policies to a 33 per cent rise in opioid hospitalizations.
The study says the province’s decriminalization policies further drove up hospitalizations by 58 per cent.
“Neither the safer supply policy nor the subsequent decriminalization of drug possession appeared to alleviate the opioid crisis,” the study concludes. “Instead, both were associated with an increase in opioid overdose hospitalizations.”
The B.C. government rolled back decriminalization in April 2024 in response to widespread concerns over public drug use. This February, the province also officially acknowledged that diversion of safer supply drugs does occur.
The study did not conclusively determine whether the increase in hospital visits was due to diverted safer supply opioids, the toxic illicit supply, or other factors.
“There was insufficient evidence to conclusively attribute an increase in opioid overdose deaths to these policy changes,” the study says.
Nguyen’s team had published an earlier, 2024 study in JAMA Internal Medicine that also linked safer supply to increased hospitalizations. However, it failed to control for key confounders such as employment rates and naloxone access. Their 2025 study better accounts for these variables using the synthetic comparison group method.
The study’s authors did not respond to Canadian Affairs’ requests for comment.

Correlation vs. causation
Chris Perlman, a health data and addiction expert at the University of Waterloo, says more studies are needed.
He believes the findings are weak, as they show correlation but not causation.
“The study provides a small signal that the rates of hospitalization have changed, but I wouldn’t conclude that it can be solely attributed to the safer supply and decrim[inalization] policy decisions,” said Perlman.
He also noted the rise in hospitalizations doesn’t necessarily mean more overdoses. Rather, more people may be reaching hospitals in time for treatment.
“Given that the [overdose] rate may have gone down, I wonder if we’re simply seeing an effect where more persons survive an overdose and actually receive treatment in hospital where they would have died in the pre-policy time period,” he said.
The Nguyen study acknowledges this possibility.
“The observed increase in opioid hospitalizations, without a corresponding increase in opioid deaths, may reflect greater willingness to seek medical assistance because decriminalization could reduce the stigma associated with drug use,” it says.
“However, it is also possible that reduced stigma and removal of criminal penalties facilitated the diversion of safer opioids, contributing to increased hospitalizations.”
Karen Urbanoski, an associate professor in the Public Health and Social Policy department at the University of Victoria, is more critical.
“The [study’s] findings do not warrant the conclusion that these policies are causally associated with increased hospitalization or overdose,” said Urbanoski, who also holds the Canada Research Chair in Substance Use, Addictions and Health Services.
Her team published a study in November 2023 that measured safer supply’s impact on mortality and acute care visits. It found safer supply opioids did reduce overdose deaths.
Critics, however, raised concerns that her study misrepresented its underlying data and showed no statistically significant reduction in deaths after accounting for confounding factors.
The Nguyen study differs from Urbanoski’s. While Urbanoski’s team focused on individual-level outcomes, the Nguyen study analyzed broader, population-level effects, including diversion.
Wallace, the biostatistician, agrees more individual-level data could strengthen analysis, but does not believe it undermines the study’s conclusions. Wallace thinks the researchers did their best with the available data they had.
“We do not have a ‘copy’ of B.C. where the policies weren’t implemented to compare with,” said Wallace.
B.C.’s overdose rate of 775 per 100,000 is well above the national average of 533.
Elenore Sturko, a Conservative MLA for Surrey-Cloverdale, has been a vocal critic of B.C.’s decriminalization and safer supply policies.
“If the government doesn’t want to believe this study, well then I invite them to do a similar study,” she told reporters on March 27.
“Show us the evidence that they have failed to show us since 2020,” she added, referring to the year B.C. implemented safer supply.
