Authorities in Latvia and Lithuania reported seizing carfentanil as an illicit drug in the early 2000s.[3][9] Around 2016, the US and Canada started reporting a dramatic increase in shipment of carfentanil and other strong opioid drugs to customers in North America from Chinese chemical supply firms. In June, 2016 the Royal Canadian Mounted Police seized one kilogram of carfentanil shipped from China in a box labelled "printer accessories". According to the Canada Border Services Agency, the shipment contained 50 million lethal doses of the drug, more than enough to wipe out the entire population of the country, in containers labeled as toner cartridges for Hewlett-Packard LaserJet printers.
