A Canadian cannabis company is recalling two batches of medical marijuana that the government claims are too potent.

Peace Naturals Project Inc. had labeled the marijuana as containing 9.07% THC. But when inspected by a third party, it was determined that it contained THC levels as high as 13.7%, Health Canada said on its website.

Though no complaints were received, the increased level of THC could present a health risk, the agency said.

Medical marijuana is legal at the federal level in Canada, unlike in the United States.

Health Canada regularly inspects marijuana batches, which are subject to compliance and enforcement measures like any other controlled substance. The agency said it has issued four marijuana recalls for reasons including mold and “questionable production practices.”
