A Canadian retail chain is surely going to save lives with their latest product.

180 Smoke Vape Store is now selling fentanyl testing kits in all of its retail stores, as well as online.

The vape shop specializes in harm reduction products, with an emphasis on smoking alternatives like vaping.

“With increasing number of opioid-related deaths and overdoses in recent months, especially due to fentanyl, we felt it was our obligation to make these strips and other testing kits available to Canadians,” said the store’s co-founder, Dr. Gopal Bhatnagar.

The fentanyl testing strips from Dancesafe use Canadian immunoassay technology to detect the presence of fentanyl and some of its known analogs in a drug sample.

Boris Giller, the other co-founder of 180 Smoke Vape Store, says that the testing strips can identify most fentanyl-related analogs, but there are still limitations that every drug user should be aware of.

“There is concern that these strips could give consumers a false sense of security due to the potential of false negatives,” Giller said. “Unfortunately, there are currently no better alternatives available easily for people worried about adulterated drugs.”

Nearly 2,500 Canadians died from opioid-related overdoses in 2016 and, more recently, fentanyl was detected in 81% of B.C.’s illicit drug deaths in September.
