Delays in new guidelines frustrate addiction experts, who call for improved efforts to wean clients from prescribed opioids

An addiction medicine advocacy group is urging B.C. to promptly issue new guidelines for witnessed dosing of drugs dispensed under the province’s controversial safer supply program.

In a March 24 letter to B.C.’s health minister, Addiction Medicine Canada criticized the BC Centre on Substance Use for dragging its feet on delivering the guidelines and downplaying the harms of prescription opioids.

The centre, a government-funded research hub, was tasked by the B.C. government with developing the guidelines after B.C. pledged in February to return to witnessed dosing. The government’s promise followed revelations that many B.C. pharmacies were exploiting rules permitting patients to take safer supply opioids home with them, leading to abuse of the program.

“I think this is just a delay,” said Dr. Jenny Melamed, a Surrey-based family physician and addiction specialist who signed the Addiction Medicine Canada letter. But she urged the centre to act promptly to release new guidelines.

“We’re doing harm and we cannot just leave people where they are.”

Addiction Medicine Canada’s letter also includes recommendations for moving clients off addictive opioids altogether.

“We should go back to evidence-based medicine, where we have medications that work for people in addiction,” said Melamed.

‘Best for patients’

On Feb. 19, the B.C. government said it would return to a witnessed dosing model. This model — which had been in place prior to the pandemic — will require safer supply participants to take prescribed opioids under the supervision of health-care professionals.

The move follows explosive revelations that more than 60 B.C. pharmacies were allegedly participating in a scheme to overbill the government under its safer supply program. The scheme involved pharmacies incentivizing clients to fill prescriptions they did not require by offering them cash or rewards. Some of those clients then sold the drugs on the black market.

In its Feb. 19 announcement, the province said new participants in the safer supply program would immediately be subject to the witnessed dosing requirement. For existing clients of the program, new guidelines would be forthcoming.

“The Ministry will work with the BC Centre on Substance Use to rapidly develop clinical guidelines to support prescribers that also takes into account what’s best for patients and their safety,” Kendra Wong, a spokesperson for B.C.’s health ministry, told Canadian Affairs in an emailed statement on Feb. 27.

More than a month later, addiction specialists are still waiting.

According to Addiction Medicine Canada’s letter, the BC Centre on Substance Use posed “fundamental questions” to the B.C. government, potentially causing the delay.

“We’re stuck in a place where the government publicly has said it’s told BCCSU to make guidance, and BCCSU has said it’s waiting for government to tell them what to do,” Melamed told Canadian Affairs.

This lag has frustrated addiction specialists, who argue the lack of clear guidance is impeding the transition to witnessed dosing and jeopardizing patient care. They warn that permitting take-home drugs leads to more diversion onto the streets, putting individuals at greater risk.

“Diversion of prescribed alternatives expands the number of people using opioids, and dying from hydromorphone and fentanyl use,” reads the letter, which was also co-signed by Dr. Robert Cooper and Dr. Michael Lester. The doctors are founding board members of Addiction Medicine Canada, a nonprofit that advises on addiction medicine and advocates for research-based treatment options.

“We have had people come in [to our clinic] and say they’ve accessed hydromorphone on the street and now they would like us to continue [prescribing] it,” Melamed told Canadian Affairs.

A spokesperson for the BC Centre on Substance Use declined to comment, referring Canadian Affairs to the Ministry of Health. The ministry was unable to provide comment by the publication deadline.

Big challenges

Under the witnessed dosing model, doctors, nurses and pharmacists will oversee consumption of opioids such as hydromorphone, methadone and morphine in clinics or pharmacies.

The shift back to witnessed dosing will place significant demands on pharmacists and patients. In April 2024, an estimated 4,400 people participated in B.C.’s safer supply program.

Chris Chiew, vice president of pharmacy and health-care innovation at the pharmacy chain London Drugs, told Canadian Affairs that the chain’s pharmacists will supervise consumption in semi-private booths.

Nathan Wong, a B.C.-based pharmacist who left the profession in 2024, fears witnessed dosing will overwhelm already overburdened pharmacists, creating new barriers to care.

“One of the biggest challenges of the retail pharmacy model is that there is a tension between making commercial profit, and being able to spend the necessary time with the patient to do a good and thorough job,” he said.

“Pharmacists often feel rushed to check prescriptions, and may not have the time to perform detailed patient counselling.”

Others say the return to witnessed dosing could create serious challenges for individuals who do not live close to health-care providers.

Shelley Singer, a resident of Cowichan Bay, B.C., on Vancouver Island, says it was difficult to make multiple, daily visits to a pharmacy each day when her daughter was placed on witnessed dosing years ago.

“It was ridiculous,” said Singer, whose local pharmacy is a 15-minute drive from her home. As a retiree, she was able to drive her daughter to the pharmacy twice a day for her doses. But she worries about patients who do not have that kind of support.

“I don’t believe witnessed supply is the way to go,” said Singer, who credits safer supply with saving her daughter’s life.

Melamed notes that not all safer supply medications require witnessed dosing.

“Methadone is under witness dosing because you start low and go slow, and then it’s based on a contingency management program,” she said. “When the urine shows evidence of no other drug, when the person is stable, [they can] take it at home.”

She also noted that Suboxone, a daily medication that prevents opioid highs, reduces cravings and alleviates withdrawal, does not require strict supervision.

Kendra Wong, of the B.C. health ministry, told Canadian Affairs that long-acting medications such as methadone and buprenorphine could be reintroduced to help reduce the strain on health-care professionals and patients.

“There are medications available through the [safer supply] program that have to be taken less often than others — some as far apart as every two to three days,” said Wong.

“Clinicians may choose to transition patients to those medications so that they have to come in less regularly.”

Such an approach would align with Addiction Medicine Canada’s recommendations to the ministry.

The group says it supports supervised dosing of hydromorphone as a short-term solution to prevent diversion. But Melamed said the long-term goal of any addiction treatment program should be to reduce users’ reliance on opioids.

The group recommends combining safer supply hydromorphone with opioid agonist therapies. These therapies use controlled medications to reduce withdrawal symptoms, cravings and some of the risks associated with addiction.

They also recommend limiting unsupervised hydromorphone to a maximum of five 8 mg tablets a day — down from the 30 tablets currently permitted with take-home supplies. And they recommend that doses be tapered over time.

“This protocol is being used with success by clinicians in B.C. and elsewhere,” the letter says.

“Please ensure that the administrative delay of the implementation of your new policy is not used to continue to harm the public.”
