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.
