Canadian police discovered black bears during a pot farm raid in British Columbia and were then surprised to find that the bears were friendly. It's not clear if the domesticated bears were pets or if they were intended as guards for the illegal drug crop.
The drug bust is just part of the pot-growers' problems. It is illegal to feed or domesticate bears. The growers face up to a year in jail for keeping domesticated bears and to help rehabilitate the animals, they have to replace the dog food the bears have been getting with natural food for the weeks before the bears go into hibernation.
