Globe & Mail: Vancouver parks smoking ban takes effect
“The Vancouver Parks Board has brought down the ban as a way to eliminate second-hand smoke and protect the health of park-goers. It also hopes to eliminate some of the 367,000 cigarette butts found in beach and shore cleanups last year.”
This actually makes some sense. Most anti-smoking laws target private property such as bars etc. which should actually be allowed to permit smoking. In this case we have public property which should be free from the associated second-hand smoke and litter nuisance.
