Health Canada has issued a warning about several banned drug products that a Calgary sex shop was selling under the headings of leather cleaner or liquid incense.

The products contain a type of amyl nitrites, commonly known as "poppers," which users inhale to heighten sexual arousal.

Officials removed the eight products — with names such as Jungle Juice Plus Leather Cleaner and Z-Best Leather Cleaner — from the shelves of Saints N Sinners at 1715 Centre Street N.W.

Using poppers can cause a dangerous drop in blood pressure — especially when used with drugs to treat erectile dysfunction — rapid or irregular heart rhythm, and a decrease in the blood's ability to carry oxygen, officials said.

"Health Canada is not aware of credible evidence confirming that alkyl nitrites are legitimately used in consumer products such as leather cleaners, room odourizers or liquid incense," the agency said.

"Health Canada's view is that even though these products are labelled as consumer products, they are manufactured and sold so that users can 'get a high.'"

Amyl nitrites — and related forms of alkyl nitrites such as butyl nitrites and isobutyl nitrites — are considered drugs under the Food and Drugs Act and cannot be sold without approval from Health Canada.

The agency said it is working with the Canada Border Services Agency to stop any shipments of any more of the products from entering Canada.  

Anyone who has used any of these products should consult a doctor, officials said.
