According to the local news site:

“It is still illegal under state law to buy or sell marijuana in any quantity or to consume it in public.”
I’d question that too, except in my opinion, weed doesn’t smell nearly as bad as cigarettes or cigars. I expect the the same kind of restrictions will apply. However, with vaporizers becoming more popular for both nicotine and THC delivery, it’s not like you have to smoke it to enjoy.
