When taxes are high... people black market cigs for that reasonThe new illegal alien slave labor force. Out west they work(ed) lettuce farms... here they're doing pot farms. And probably lots more places...
Local pot shops buying illegal weed on the black market, listing it under fake invoices from "legitimate" growers and falsifying the records. Big money in passing weed that's not taxed or properly inspected/tested, and the state either doesn't care enough or have enough manpower to enforce their own laws.
I'm guessing some of both.
Everyone said, "Legalize it and tax it." Yeah... that'll stop the black market.
