But on Monday, Health Canada warned that illicit drug take a look at strips may not detect harmful substances, together with xylazine and fentanyl.

“No test is 100 per cent effective at detecting all potentially dangerous substances in illegal drugs,” Health Canada mentioned in a press release.

Hart palms out no matter assessments she will be able to get her palms on.

“The demand — we can’t get enough strips.”

Drug provide and testing researchers Global News spoke with say they perceive why Health Canada would take a cautious strategy towards take a look at strip utilization, however argue the testing kits are higher than nothing.

Daniel Werb, an affiliate well being coverage professor on the University of Toronto, advised Global News take a look at strips are mostly used to detect fentanyl, with an accuracy of discovering a presence of lower than 5 per cent, which he mentioned is sufficient to show deadly.

Werb, who’s concerned in commercializing a brand new drug testing expertise, mentioned that’s the next degree of detection than mass spectrometry applied sciences that clinics use to check medication, which might detect a broader vary of medicine current however not a presence under 5 per cent.
