Yes and no, but demand for the other drugs would not necessarily be high.. and therefore not very profitable. It takes hundreds of billions of dollars to finance the huge violent military cartel organizations and their subsidiaries.

For who could be free when every other man's humour might domineer over him? - John Locke (2nd Treatise, sect 57)
