TACOMA, Wash. — Matt Mason and two friends drove to Tacoma from Indianapolis, ready to unveil what Mason called "tobacco grinders" at CannaCon.
That's canna as in cannabis and con as in convention.
Mason calls them "tobacco grinders" because he comes from a state where possession of a certain amount of marijuana is prosecuted as a felony.
The idea for the shiny, colorful metal, laser-engraved grinders came one quiet evening at home.
"Me and my buddy were smoking tobacco in the garage, and we thought it would be a great idea," he said Thursday.
