Results from 92 samples checked: February 13 – 26, 2021

Key findings

  • 92 samples were checked: 66% were substances1 and 34% were used paraphernalia2
  • 10% of the samples checked were known to be associated with an overdose: each of these samples contained fentanyl and most contained one or more benzodiazepine or benzodiazepine-related drug
  • 55% of the samples checked were expected3 to be fentanyl
  • 65% of expected3 fentanyl samples checked contained one or more benzodiazepine or benzodiazepine-related drug
  • Meclonazepam, a benzodiazepine-related drug that has just recently started presenting in Toronto’s unregulated drug supply, was found in 12% of expected3 fentanyl samples checked

Expected fentanyl substances

  • 92% (22) of expected3 fentanyl substances checked4 contained fentanyl and other drugs, including:
  • 91% (20) contained caffeine
  • 50% (11) contained etizolam (benzodiazepine-related) (!)
  • 41% (9) contained despropionyl fentanyl (4-ANPP) (!)
  • 14% (3) contained norfentanyl (!)

Unexpected noteworthy drugs found in other expected substances

  • 14% (5) of the remaining substances checked,4 meaning substances that weren’t expected3 to be fentanyl, contained one or more unexpected noteworthy drug, including:
    • 50% (1) of expected cocaine substances contained phenacetin (!)
    • 100% (3) of expected crack cocaine substances contained phenacetin (!)
    • 33% (1) of expected crack cocaine substances contained levamisole (!)
    • 100% (1) of expected Percocet substances contained fentanyl (!)

Notes

1 | Substances: Two types of samples are accepted by Toronto’s drug checking service: substances and used paraphernalia. Substances could be a small amount of powder, a crushed bit of a pill, blotter, or a small amount of liquid.

2 | Used paraphernalia: Two types of samples are accepted by Toronto’s drug checking service: substances and used paraphernalia. Used paraphernalia could be a used cooker or filter, or leftover liquid from a syringe.

3 | Expected (drug): When a sample is submitted to be checked, the drug that sample is expected to contain is recorded. We call it the “expected drug”. Knowing the expected drug helps us tailor our harm reduction advice. It also helps us understand contamination to drugs rather than combinations of drugs (e.g., fentanyl was found in a cocaine sample rather than fentanyl and cocaine were found together).

4 | Reason for reporting only substance samples: While Toronto’s drug checking service checks both substances and used paraphernalia, we’re sharing findings from substances only. Paraphernalia, like cookers, are often re-used. The mass spectrometry technologies used for this drug checking service are so sensitive that very trace amounts of drugs may be found. This means that when paraphernalia is re-used, drugs from past use may present in the results for the sample that is being checked. This can interfere with up-to-date drug supply monitoring, so we’ve excluded used paraphernalia from this report.

(!) | Unexpected noteworthy drug: “Noteworthy drugs” are drugs that that (i) are linked to overdose or other adverse effects, (ii) are highly potent or related to highly potent drugs, or (iii) may not be desired by some clients. Noteworthy drugs are flagged when they are unexpectedly found in checked samples.
