"I bought a topical called Crystal Gardens Massage oil for my sciatica pain that worked well. I’d like to get more."
It is legal for recreational users to buy limited amounts of marijuana from dispensaries in Oregon, but you must be within the state of Oregon to purchase. It is illegal to transport over state lines. There is some reciprocity with medical marijuana recommendations, for instance if you have a CA rec you can purchase marijuana with that when in Nevada. The answer to your question is that if you are in CA at the time you can not purchase your product unless you are within the state of Oregon.
Hope this helps!
