Quebec producer Great White North Growers Inc. has issued a recall for some Lunaire Nouvelle Lune dried cannabis products after tests showed elevated levels of arsenic, a toxic heavy metal.

The recall notice, posted Thursday on the Health Canada website, identifies the affected products as 3.5-gram packages of Lunaire Nouvelle Lune dried cannabis with lot number 1001470A, packaged on Oct. 31, 2025, and sold through authorized retailers in Quebec, the Société Québécoise du Cannabis (SQDC).

Harmful to health

Arsenic is a naturally occurring element that can be harmful to human health if ingested at elevated levels.

Prolonged exposure has been linked to an increased risk of cancer and potential damage to the skin, lungs, heart, brain, kidneys and reproductive system, the notice says.

It may also pose risks during pregnancy and breastfeeding.

Officials say the recall was triggered after Great White North Growers conducted non-routine additional testing on the lot, which revealed the contamination.

Approximately 869 units of the product were sold between Oct. 31, 2025, and Jan. 13, 2026, through authorized cannabis retailers in Quebec.

So far, there have been no reported health complaints or adverse reactions related to the recall.

What consumers should do

Health Canada and the company are urging anyone who purchased the recalled product to stop using it immediately.

Consumers can return unopened products to the retailer where they were purchased, or safely dispose of open products out of reach of children and youth.

Customers who experience any health or safety issues connected to this or other cannabis products are encouraged to fill out Health Canada’s Cannabis Reporting Form online.

The recall affects only the specific lot listed.

Other Lunaire cannabis products are not part of the recall.
