As someone who's had his door kicked in by the cops, tens of pounds of buds seized, kilos of powder, along with stacks of cash, money counters, and firearms....i can tell you that high volume west coast bud/concentrate dealing is the same as, and often in concert with every other illicit thing a person may deal in. you're right about the trust tho, trust is a big thing.

although yes, i did deal with my growers directly.
