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.
John Percy, 67, smokes, vapes and bakes his cannabis to control pain in his hip caused by osteoarthritis. The former Green Party leader had been ordering his medical marijuana from OrganiGram in Moncton, N.B., the only licensed producer in Atlantic Canada.
He said his pain was an “eight out of 10.”
“I was shocked,” said Percy, when he first learned of the voluntary recall in late December. The letter said the marijuana he consumed “tested positive for bifenazate and/or myclobutanil, both unapproved pesticides and not registered for use on marijuana.”
“I assumed like most patients that the product would be organic,” he said.
According to Health Canada hydrogen cyanide interferes with how oxygen is used in the body and may cause headaches, dizziness, nausea, and vomiting. Larger concentrations may cause gasping, irregular heartbeats, seizures, fainting, and even death.
