The RCMP has broken up a suspected drug-smuggling crew which was blending their cocaine with asphalt powder to evade detection as it was flown from Mexico to Trudeau airport as reported by CTV:
The suspects used an advanced chemistry process called "molecular docking." This method would chemically bind the drug with the asphalt in order to smuggle large quantities of cocaine into the country. A chemist would then extract the drug out of the asphalt.
Of course, among the busted defendants are those with reputed ties to the Montreal Mafia and Hells Angels as reported by Paul Cherry for the Montreal Gazette.
