Oregon here. Too new to say much, but I am elated that my state has jumped on the bandwagon. Our rules are set up pretty fairly, IMO:
4 plants per household, 8 oz dry flowers for every adult, able to transport 1oz at a time. Can't remember limits on solid foods and concentrates... Growing and consumption must be out of public view, but that doesn't mean just in your living room... Smoking behind a fenced-in front yard courtyard is A-OK once the law takes effect in July 2015.
No distinction has been made yet on immature plants or penalties for having a killer harvest (one could easily exceed the 8oz limit with even just one massive outdoor plant). The OLCC (Oregon Liquor Control Commission) is meeting early 2015 to fine tune the rules. I'm hopeful they will specify a 4 plant limit for MATURE plants and allow an additional 4-8 immature plants/clones/seedlings, similar to what our medical program allows. The measure did not take SOG growing into account, unfortunately.
Not many people are talking about it where I live, but Portland seems to be pretty energized over the new laws--which won't take effect until July 2015, however the DA won't prosecute in THAT county now. I'm hoping my county follows suit...
If anything, additional media attention and the passage of time toward the "full legalization" date will open up more conversation--which I'm most excited about. It'll be nice to carry around a few nugs in my keychain "pill" bottle along with some papers in my wallet, and be 100% in compliance with state law.
I think it's a little lame that retail businesses won't open up until 2016. I think this date is subject to change, though--I'd love to see the retail business side of things fasttracked.
