None of which has anything to do with your claim that:
“They’ll just buy it on the black market for cheap. In the meantime, Marijuana legalization will provide cover for black market sales.”
The numbers refute that contention.
It has to do with my statement that the full impact of legalization have not yet been realized in full. Note the new “sticker shock” in the OP will reduce legal sales and balloon the black market so tax/fee revenue will go even smaller than .007% of current state budget.
