A Nova Scotia man has joined the ranks of people suing licensed producers over pesticide-laden pot, adding more questions about Health Canada’s claim that people who consumed the tainted products were safe from harm.

The latest proposed class action is against Mettrum and is led by Halifax-based Wagners Law Firm, which is also seeking a class action against OrganiGram on similar grounds. Toronto-based law firm Roy O’Connor announced a proposed class action against Mettrum two weeks ago. All three cases are seeking certification by the courts.

The man listed in the new proposed class action claims he became violently ill after consuming medical marijuana purchased from Mettrum.

The Globe and Mail reported that a group of veterans is also amassing a file of evidence detailing illnesses after exposure to tainted products with symptoms that include becoming bedridden, nausea and breathing difficulties.

The banned pesticides in the proposed class actions include myclobutanil and bifenazate, which aren’t approved for use on cannabis and haven’t undergone safety testing for humans.

A court must certify the proposed class-action lawsuits before they can go forward. Canopy Growth Corp., which bought Mettrum at the start of the year, and Organigram have vowed to fight the allegations.
