They wont take a piece, they will eat the whole damn thing! Once the corporations come in they will buy lobbyists to create regulations making it illegal for anyone not able to pay the huge fees to grow more than a small number of plants for personal use. That's basically what just happened here in CO. I didn't vote in your poll since I live in CO, but obviously I would vote, HELL NO, keep it MEDICAL.
I like the points you made. I also agree that can happen that way and it will surely happen that way if you focus on keeping it illegal while the lobbyist do exactly as you said. So my advice would be to go after the lobbyist and/or explain to the government your point of view. Get a union together.....Don't try and keep it illegal and continue the process of our laws doing more harm than good.
Hell it is illegal and already CALI's biggest cash crop! I am looking for legalization to spread like wildfire once CALI does it and is much better off for doing so......I hope every state in the US follows suit!
