Canada has seen a drastic shift within the unregulated drug provide with the emergence of benzodiazepine-adulterated opioids (also referred to as “benzo-dope”). Benzodiazepines have been detected in as many as 60 per cent of overdose deaths in British Columbia.
Current information from B.C. has noticed a gentle rise in opioids testing optimistic for benzodiazepines between August 2020 and April 2021, from a low of 5 per cent to a excessive of 25 per cent.
British Columbia is just not alone in seeing this development: information from Toronto has proven that this situation is much more outstanding. Throughout the identical time interval, there was a rise from 45 per cent to 57 per cent in samples containing etizolam, a selected benzodiazepine-like compound.
Generally prescribed benzodiazepines embody medicine like Xanax and Valium. These drugs deal with quite a lot of situations equivalent to anxiousness and insomnia and have been used because the Nineteen Sixties.
Nevertheless, what’s being detected in opioids in Canada should not pharmaceutical medicine. They’re medicine from the benzodiazepine class which can be neither prescribed nor utilized in medication in Canada, which means they might possess unknown strengths or side-effects. Since benzodiazepines are sedatives, combining them with one other kind of depressant, like opioids, considerably will increase the chance of overdose.
As researchers in substance use, we questioned whether or not the growing provide of benzo-dope within the unregulated drug market would saturate the opioid provide in an analogous approach fentanyl did to heroin years in the past. The info appear to counsel we needs to be ready for the unregulated drug provide to regulate to a brand new regular.
On this context, there are important public well being points that have to be thought of.
Emergence of ‘benzo-dope’
The growing availability of benzo-dope is trigger for concern provided that when taken collectively, the mixed results of benzodiazepines and opioids can lead to overdose and dying. In response to the B.C. Coroner’s Service, there was a considerable improve in benzodiazepines detected in illicit drug toxicity deaths, from 15 per cent in July 2020 to 60 per cent in Might 2021.
Most individuals don’t intend to eat benzodiazepines with their opioids. As a consequence, individuals wanting to make use of opioids might unknowingly improve their danger of overdose from benzodiazepine adulteration.

Benzodiazepines are additionally slower to take impact in comparison with opioids, which means somebody can expertise delayed overdose signs. Thefts and sexual assaults have additionally been reported after individuals got benzodiazepine-adulterated opioids with out their data and consequently knocked into an unresponsive state.
The explanation behind the adulteration of benzodiazepines in opioids is unclear. Some counsel they might be added to opioids to provide related results at a decrease complete price to drug suppliers, or deliberately used to delay or improve the fascinating results of opioids. Regardless, there’s rising proof that co-use and dependence on opioids and benzodiazepines is happening in parallel to the rising provide of those medicine.
Deaths from opioid overdose could be prevented with naloxone, which counteracts the consequences of opioids. Nevertheless, there is no such thing as a evidence-based antidote to reverse the consequences of benzodiazepines with out potential penalties equivalent to withdrawal or seizures.
Moreover, as a result of problems of benzodiazepine withdrawal, many dependancy therapy suppliers is not going to admit people who check optimistic for benzodiazepines. Because of this, individuals might not be capable of entry substance use therapy due to an imposed adulterant to their medicine.
Challenges detecting benzo-dope
Drug checking companies have been carried out throughout Canada to observe the unregulated drug provide and supply individuals with well timed details about the contents of their medicine. In lots of settings in B.C., benzodiazepine check strips are used alongside a expertise referred to as Fourier-transform infrared spectroscopy to detect the presence of benzodiazepines. Nevertheless, limitations of those applied sciences generally trigger benzodiazepines to be missed when current in small concentrations.
Etizolam, the commonest benzodiazepine-like compound present in opioids, is especially tough to detect utilizing point-of-care drug-checking applied sciences due to its chemical construction. Thus, there could also be an under-reporting of how pervasive this situation actually is in B.C. and elsewhere in Canada.
A brand new wave of the overdose epidemic?
There have been a lot of essential life-saving responses to handle the fentanyl-driven overdose epidemic, equivalent to supervised consumption websites and expanded distribution of naloxone. Nevertheless, much less consideration has been paid to the rising situation of benzo-dope and its related well being harms. As this public well being emergency worsens, it is necessary that we incorporate a broader understanding of overdose danger that goes past opioids in our efforts to stop, deal with and reply.
It’s too quickly to know whether or not benzo-dope will saturate the unregulated opioid market. So long as there stays an absence of any authorized framework to advertise a safer provide of medication (secure provide and decriminalization), there’ll at all times be a stage of unpredictability within the unregulated opioid provide that may hurt individuals’s well being.
