Marijuana grown in British Columbia, known to contain up to 30% THC by weight and widely considered to be some of the best in the world.

Dealer: That Florida loser called again and I told him I had some more of that BC Bud. We'll just keep selling him your homegrown for twice what it's worth.
Buddy: Sweet. What a tool. Let's get high.
