Organigram Inc. said on Monday that it has wrapped up an internal investigation into a product recall announced in December but the findings are "inconclusive," with "no hard evidence leading to the source of the contamination." The company also said it would offer full refunds to customers who bought the tainted product, after refusing over the past two months to give patients their money back. The refunds will cost $2.26 million, Organigram said, a financial hit worth slightly more than the total sales the company reported in its most recent quarter. Organigram is facing the prospect of a class-action lawsuit over the tainted medicine, which some patients say has left them with serious health effects, including lung problems, rashes and persistent nausea and vomiting. At least two law firms are considering launching actions that would force the company to surrender profits related to the product. Organigram is one of three medical-marijuana companies involved in a banned-pesticide scare uncovered by The Globe and Mail in December that has swept the medical marijuana industry) The investigation has raised concerns about Health Canada's oversight of the sector - particularly as Ottawa prepares to legalize cannabis for recreational use, creating what is expected to be a highly lucrative business. Mettrum Ltd., Organigram and Aurora Cannabis Inc. announced recalls late last year after the pesticide myclobutanil was discovered in medicine sold to clients. Myclobutanil is outlawed on plants that are smoked because it produces hydrogen cyanide when heated and can cause serious health problems. Monday's announcement that Organigram could not determine the source of the problem casts further doubt on the credibility of the industry, which is licensed by the federal government to produce safe pharmaceutical products for patients who use them to treat everything from cancer-related pain to epilepsy. Several patients who consumed the tainted cannabis say they are not sure if they can trust the products again, particularly since Health Canada does not require regular safety testing for all 38 companies in the industry. Organigram maintains it has never used myclobutanil, which is known in the industry as an easy but dangerous shortcut to dealing with outbreaks of mildew that can threaten crops. The company said it believes the banned pesticide may have got into its plants through "inputs" in the growing process, such as contaminated fertilizer or soil. In particular, Organigram officials suspect peat moss the company used last year may have been treated with myclobutanil before entering the facility, but the company has no conclusive proof and no longer uses the peat moss. "The company has instituted a series of new protocols to prevent a recurrence of any issue of this nature," Organigram said. "All inputs from outside suppliers are now tested before they are used. Inputs include such things as seeds, growing medium, fertilizers, water, etc." Organigram once marketed itself as an organic grower of cannabis, but lost that designation from global certification body Ecocert after the pesticide issue arose and will have to reapply. The company said it is now testing all of its product lots for pesticides. The Globe and Mail first uncovered the myclobutanil problem in Canada's federally regulated medical-marijuana industry in December, revealing that a recall at Mettrum was due to the pesticide. However, neither Health Canada nor the company included that information in their official announcements of the recalls. A day after The Globe article was published, Organigram issued a public notice saying it, too, had been found selling products that contained myclobutanil, which is well known throughout the industry as a banned product. The problem was discovered almost by accident when Aurora tested a bulk shipment it bought from Organigram for resale to clients. The myclobutanil scare exposed a troubling blind spot in Canada's regulatory regime. Health Canada said recently that it had not required the industry to test for harmful pesticides because the companies know they were not allowed and they should not be using them. Since the recalls, Health Canada has mandated that Organigram and Mettrum, which has been purchased by Canopy Growth Corp., test all their products for pesticides. Health Canada has also said it would introduce random testing for pesticides. However, some companies do not think those efforts are enough to win back the confidence of patients. CanniMed Therapeutics Inc., based in Saskatoon, has commissioned independent lab tests on some of its products and said it will publish the data to show consumers its medicine contains no banned pesticides. Myclobutanil is approved for use on foods such as grapes because it can be safely metabolized by the digestive system. However, when smoked, it creates hydrogen cyanide that enters the bloodstream directly through the lungs. Health Canada said in September it had a zero-tolerance policy for contaminants such as myclobutanil and would consider revoking the licence of a company found using it. But since the pesticide was discovered in legally produced marijuana, Health Canada and the companies involved have tried to play down the problem. Mettrum and OrganiGram told clients the chemical was approved for fruit, giving the impression of safety, while leaving out the details about what happens when myclobutanil is heated. Meanwhile, Health Canada referred to the residue detected as "trace amounts" that are "low risk." Warren Porter, a U.S. toxicologist, has said Health Canada and the companies "have no idea whether or not that's true" because there are no scientific data to support the assurances the risk is low. - --- MAP posted-by: Matt
