So. If the legalization passes muster, there will be a good deal of restrictions on it's distribution and sales and that seems to be concern to growers?

I don't read anything in it that will change in any way manner or form medical marijuana. Currently CA breathes a sigh of relief from Obama's mandate to justice, but no grower is totally free of paranoia concerning the feds. Furthermore, I highly doubt many people with the capability and wherewithal to successfully grow MJ are being held back by the current environment of medical marijuana card accessibility. I see a large increase in demand.

What's of more concern from my perspective of a small grower is the overall national move towards acceptance of MJ. Am honest economic analysis of the situation would have to admit that some percentage of product produced in CA makes it's way to other states. As other states implement programs and laws that increase local populations abilities to grow supply will increase.

Until such time as the federal governments complete decriminalization there will always be a hefty enough risk involved to somewhat deter the casual potential grower.
