“Texas is trafficking central.”
Did you miss these four words? You seem to believe these are separate battles- they, are not. They are one and the same.
Everything is connected but some things are a lot more connected than others.
Grow houses in Washington state are only slightly connected to the drug war at the border. And the impact of that connection could go either way. Could be that legal domestic production will reduce demand for imports, reducing the violence. Could be that legal production will increase demand by legitimizing marijuana use, causing increased violence as profits rise.
Of course complete legalization nationally would eliminate the profit margins of illegal importers, but that would be against the conservative principles of the Food and Drug Administration.
