Montreal's Direction régionale de santé publique (DRSP) is warning the public to watch out for fentanyl mixed in with cocaine. \nThe warning comes following a death that occurred after "consumption of a whitish powder containing cocaine and fentanyl," according to the Santé Montréal website.Fentanyl is 40 times more powerful than heroin and 50 to 100 times more potent than morphine, says Santé Montréal, which means that tiny amounts can have fatal consequences. \nEditor's Choice: Verdun Residents See A Dark Side To Being Named One Of The World's Coolest Neighbourhoods\n\n\n23%\n\n\nOf opioid deaths in Quebec involved fentanyl\n\n\n\nThe statement also said cocaine users can be exposed to fentanyl without their knowledge resulting in a high risk of death.\nThe city's regional public health department advises people to avoid using cocaine alone, and to stagger the times when group members take cocaine so not everyone's using it at once.\nAVIS À LA POPULATION | Un décès est survenu suite à la consommation d’une poudre blanchâtre contenant de la cocaïne et du #fentanyl.

The "good samaritan law" guarantees immunity from prosecution for witnesses of an overdose who call 911.\nTwenty-three percent of opioid-related deaths in Quebec involved fentanyl in 2016, according to Health Canada.
