A medical marijuana patient in Lower Sackville, N.S., said he's worried after the marijuana he consumed for nearly a year was recalled by Health Canada because it was grown with two pesticides that, if heated, can emit hydrogen cyanide. The former Green Party leader had been ordering his medical marijuana from OrganiGram in Moncton, N.B., the only licensed producer in Atlantic Canada. (CBC)According to Health Canada hydrogen cyanide interferes with how oxygen is used in the body and may cause headaches, dizziness, nausea, and vomiting. He believes Health Canada should test marijuana for more than 13 compounds to ensure it's safe for consumption. Percy said he and other licensed medical marijuana patients have discussed starting a class-action lawsuit.
