Edmonton police allege that three drug dealers trying to drum up business were handing out cocaine samples to young people.
Police spokesman Scott Pattison says the trio parked a truck in a popular location on the city's south side and began luring potential customers over.
Pattison says their contact information for future purchases was printed on the back of five-gram packages of the drug.
Pattison says it's like they were giving out their business cards.
Jesse Levesque, 22, Chris Hefford, 22, both from Edmonton, and Dan Friedrick, 25, of Spruce Grove, Alta., have been charged with trafficking, possession for the purpose and living off the proceeds of crime.
