How Much Marijuana is Sold to Black Market Operations?

Thread starter #1
I was curious if anyone knew how much of marijuana produced goes towards black market operations. I am especially interested in california, I am aware of the large amounts grown in california, but how much of it actually make it to the dispensary?

If I were you I'd watch various marijuana documentaries and try to find out that way. The True Tale of American Marijuana is a good one. Then there's the network televised Marijuana INC. But there's plenty more out there.
