Here we are trying to take a product anyone can grow safely  and decriminalize it for corporations to grow but somehow make it illegal for individuals to grow. I smell a constitutional challenge here.

The smart way to handle this is to provide federal guidelines for growing and turn it over to cities and municipalities to provide individual licences to anyone that wishes to grow for personal use. The city would get the licencing revenue as they will have to deal with any issues related to enforcement such as people growing beyond personal use limits.

If they walk down the path they are headed they will do nothing to stem illegal production but they will add a new phase to criminal activity and that is counterfeit medical/recreational marijuana. Lets face it if a dispensary is buying product from a licenced producer and then selling it to the recreational market they are going to supplement their inventory from there own production to maximize profits.
