These days in BC and the lower mainland in particular, the “opioid crisis” is no secret. I don’t believe anyone would disagree that we as a society are in the throes of an unprecedented health crisis.
Fentanyl was synthesized in 1960. It is 50-100 times more potent than morphine but considered significantly safer due to the decreased risk of respiratory depression in patients. Therefore, it quickly became the preferred anesthetic for cardiac surgery. When it began being available by prescription to treat pain, people of course began abusing it.
Fentanyl was much cheaper than heroin so dealers often cut heroin or other drugs with small amounts of fentanyl. The unintentional fatalities by overdose where fentanyl was detected date back to the early 2000s, however, the problem skyrocketed in Canada beginning in about 2014-2015. People are not just unwittingly consuming drugs laced with fentanyl now; it has become a drug of choice and a profitable commodity along with its much more potent analogues.
