Carfentanil on a serious rise

Purple heroin can be in granular form or in small bricks of a mauve colour. Along with fentanyl and carfentanil, the 'heroin' may also be cut with potent painkillers.

Cops seized 300 grams of carfentanil along with fentanyl and cocaine following an investigation by ALERT's gang unit in Lethbridge.
