Oregon’s HB 3000 brought in more complex rules surrounding hemp, basically intended to rectify situations around intoxicating hemp products. This redefined “adult use cannabis item” to include hemp-derived cannabinoids if they exceed a threshold. Under an emergency rule, this was set to be more than 0.5 mg of THCs. In short, hemp delta-9 is allowed, but is regulated by the Oregon Liquor and Cannabis Commission (OLCC).
