In Honolulu I'd end up smoking out in public sometimes almost every single day, at Ala Moana mall, Walmart, the beaches, bus stops, alleys, abandoned buildings, parks, outside the doors of clubs, walking along backroads of Ewa....
I admit that some spots were downright stupid to smoke at and even got caught at the Ala Moana park once by an undercover, but he didn't say anything until we finished the joint then told us to split.... they are looking for stuff a lot worse
While driving around on the island and you can usually smell someone burning somewhere... it's great!
I wouldn't dare smoke in public where I live now, unless I'm in a well secluded spot.
