After discovering cocaine laced with fentanyl, Montreal Public Health warns recreational drug users to exercise caution.
What is Fentanyl?
Fentanyl is a cheap but powerful synthetic opioid analgesic that is similar to morphine but is 50 to 100 times more potent. The fentanyl equivalent of a few grains of salt could be fatal. Drug dealers are using it as a filler, lacing drugs that come in pill, powder or injectable form. There is even evidence that fentanyl may be laced in marijuana.
