“Until there is some registry to cross-check tokers with gun purchases or CCW license holders, its just another law to be ignored”.
You’re exactly right.
The police chief in Honolulu sent out a letter telling registered marijuana users to turn in their guns.
It think the Chief has been "reasoned with" after considerable protests, and people who currently own guns will not have them confiscated.
It appears medical marijuana users will not be issued gun permits in Hawaii.
