The over riding question is what the feds are going to do about this. This is the latest I have seen of any indication of the fed intentions and it doesn't appear they are going to ignore enforcement on production and sales.
From the link:
Gil Kerlikowske is U.S. President Obama’s director of the Office of National Drug Control Policy—more commonly known as the U.S. “drug czar.” His long career in law enforcement included serving as police chief in two border cities: Buffalo and Seattle.

Q: In the November elections, two states—Washington and Colorado—voted to legalize marijuana for recreational use. President Obama has said that the U.S. government has “bigger fish to fry” than to go after recreational users in states where it is legal. Where do things stand with regard to producers and distributors of marijuana, which is still illegal under federal law?

A: You’ll continue to see enforcement against distributors and large-scale growers as the Justice Department has outlined. They will use their limited resources on those groups and not on going after individual users.
