BC Bud is a generic term for several potent Cannabis indica-dominant varieties (e.g. BC Arctic Sun, BC God Bud) naturally grown in the Canadian province of British Columbia. The term has almost become a brand name, especially in California, Oregon, Alaska, Idaho and Washington, to which most of the province's cannabis is exported. It is often referred to as "beasters" or "the beaster" 
The United States Drug Enforcement Administration considers BC production to be a major problem, given the porous United States-Canada border, and has launched several major initiatives to cut down on its flow, including collaborative operations targeting marijuana activists such as Marc Emery. It has even been discussed in the documentary, The Union: The Business Behind Getting High which chronicles the distribution, production and economics of marijuana.
A study released on October 4, 2006 by the University of Victoria Centre for Addictions Research of BC and Simon Fraser University Applied Research on Mental Health and Addictions indicated cannabis use is more widespread among British Columbians than the rest of Canadians.
However, a high tolerance for cannabis use in BC and an awareness of the role of it as an export cash crop (worth an estimated $6 billion annually) has tended to make it difficult for Canadian or American authorities to intervene effectively. This remains a significant point of contention between the US and Canada, and is one of many US-Canada border problems driving changes to both nations' policies.
The early history of Cannabis production was centred in hippie communities in the Gulf Islands and Kootenay area, in climate conditions perfect for outdoor growing. It is believed that much of the Cannabis currently sold for export originates from hydroponic grow-ops in the Lower Mainland, with significant amounts still added by outdoor growers throughout the province.
BC has many compassion clubs, head shops and activists challenging the current legal and social views on cannabis. Larry Campbell, a Canadian senator and Vancouver's former Mayor, has called for the decriminalization, and legalization, of cannabis in British Columbia.
From a commercial point of view, the fact that many growers in BC informally cooperate to keep quality high, while competing fiercely in an illegal business, is of interest to some in the agricultural economics community, as well as students of trademarks, agricultural policy, black markets, and agorism. British Columbia is increasingly known for the premium quality of its marijuana.
