As Canada rolls towards legalizing marijuana for recreational use, History offers an insider's look into Canada's estimated multi-billion dollar marijuana industry through the eyes of one grassroots trailblazer in the new original docu-series Bud Empire. The series follows Kelowna pot pioneer Bob Kay as he navigates his medical marijuana dispensary through the burgeoning green rush. As big business and politicians threaten to make independent head shops like Bob's history, he must find a way to weed out the competition and solidify his place in the new frontier.Bud Empire premieres just ahead of the Senate's final vote on Bill C-45. If approved, marijuana will become legal for retail purchase and Canada will become the first advanced industrialized nation to legalize and regulate marijuana from production to consumption. Experts currently estimate that the base retail market of recreational marijuana could reach up to $8.7 billion annually, with $1 billion per year in tax revenue from all marijuana sales.
