Canadian government & THC cartridges
The Canadian federal government controls the sale of cannabis products and makes revenue through a cannabis federal excise duty.
On October 19, 2019, during the EVALI outbreak, THC cartridges were approved for sale in Canada. Remember, the lung injuries were caused from illegal THC cartridges.
Health Canada acknowledges the cause
In December 2019, Health Canada was questioned by CBC News about the cause of EVALI because the Canadian government approved the sale of THC cartridges during the EVALI outbreak. Health Canada clearly communicates that they understood EVALI was being caused by illegal THC cartridges and not from vaping nicotine.
