Here in Maryland it's been illegal to smoke in the workplace (including vehicles) and any enclosed building such as offices,stores,shops and such. Some cities and towns have passed laws making it illegal to smoke in any building including bars- even the private clubs like the moose .
I quit over 4 years ago. Just walked away from a pack to pack and half a day habit for 20 years! Haven't had a smoke since. It was tough at first but after the 2nd week it was a breeze. I still get the urge to have a Marlboro every now and then but it passes quickly. I do miss the occasional good cigar
