If they take it over it will end up a mess. The laws will be so burdensome that you might as well just make it illegal again. They will charge enormous fees and taxes which will keep prices high. Then you will have the industrial growers who will grow shit that you won't have a clue what it is or whats in it. It would end up eventually in the hands of big pharma and we'd be right back where we started from, taking poison.
