With the legalization of marijuana in Canada, it's inevitable that more cars will be imbued with that distinctive odor. And it's not one that fleets can tolerate. Regardless of the consequences for the driver, cleaning the car itself poses a problem, as marijuana smoke is notoriously hard to eliminate.
A U.S.–based company claims to have the solution in its patented "cyclone treatment". NuVinAir claims it can fully remediate marijuana smells. The process uses oxidation to change the chemical composition of the marijuana residue, effectively rendering it inert, the company says on its website. A water-bottle-like vessel fits into the car's cupholder and releases a dry vapour into the car. Two treatment levels are available – a refresher and a restoration level.
