In Afghan fields, the poppies grow

Afghanistan has produced more opium than the world needs this year. This raises the question, is the price of heroin vulnerable to market forces? Is the financial bottom going to fall out of the heroin trade? Would cheap heroin affect any potential user’s decision to try it? (But it was ON SALE! could be a good defense?) Will dealers be offering coupons or twofers to drum up business? What will this do to Mob profits?
