Living in the Nelson area you hear about 'Terry' all the time.  Sure Terry was bummed at first when pot was legalized.  However there was instantly supply shortages at a lot of the stores, who did the suppliers turn to?  The obvious solution was to just buy any bud off of Terry that passed the testing.  Terry has been a part of the legal supply chain since nearly day 1.  In fact I hear stories of people who are doing way better than they ever have before.
Terry has just evolved with the times and now has a storefront!
EDIT: The oil business especially has gotten huge with outdoor growers.  While a lot of the outdoor stuff isn't up to standards, people are running miniature chemical plants to provide a lot of oil to theses suppliers.
