The official PRINT ORS is available at law and public libraries around Oregon. (But call first to make sure your library has it in print. Not all libraries get the official print version.)
Note that any legislation passed in the 2016 and 2017 Oregon legislative sessions WILL NOT appear in codified format until the 2017 Oregon Revised Statutes are published in late 2017 or early 2018.
When Oregon Laws are codified*, they can be scattered all over their corresponding legislative subject compilation, the Oregon Revised Statutes, so, unless you are a researcher with too much time on your hands, I recommend you start with one of the following resources until you become very familiar with all the new cannabis laws, statutes AND regulations – and there will be new cannabis laws until you die or until the world’s lights go out, whichever comes first:
1) Oregon Revised Statutes (ORS): the 2015 ORS, which has not yet been posted online, will be the first ORS with codified recreational cannabis statutes. Toss the word “cannabis” into the ORS search box. You might want to toss in the word “marijuana” just to make sure you didn’t miss anything.
2) Laws & Regs from OHA: Oregon Medical Marijuana Program (OMMP), which links to their OMMP Administrative Rules, Statutes and Legal Information webpage.
It’s not easy to find a simple online explanation of the difference between Official and Unofficial sources of law. My explanation may fill in that gap – or not, depending on your specific question. (And a blog post this long can hardly be called “simple,” but such is life — and law.)
1) In a nutshell, an official source is a source that has been authorized by an official body, such as a court or a legislature. In Oregon, for example, we have the official statutes of Oregon, published in the Oregon Revised Statutes (ORS), by the Oregon Legislature, through Legislative Counsel. (This official statutory compilation should not be confused with Oregon Laws, which is the official session law compilation.)
In response to the person who asked (in a Comment to this post – and thank you for the question – it is an excellent one!) the difference between a session law and a code, specifically between the Oregon Revised Statutes (ORS) and the Oregon Laws, I offer this. It is about as brief a description as can be made, but it is followed by suggestions for further reading.
(Keep in mind, that this is interesting stuff to law librarians and not necessarily to others, so you can always visit your local law library to see and hear and not just read about these government publications. We love this stuff: a previous Washington D.C. tour highlight for a bunch of us law librarians was a visit to the Office of Law Revision Counsel that prepares the U.S. Code (not to be confused with the session law, the U.S. Statutes at Large).
Oregon Laws: a chronological compilation of laws passed by the Legislature and signed by the Governor. Published officially by Oregon in a set called, Oregon Laws.
