After Cats, Ecigs are tied for second place with GPS navigators for the best things that ever happened for me.
I vape everywhere but very discreetly and I bother nobody nor have I been addressed over the issue. You can not police vaping because there is no evidence. But that doesn't mean you need to be a showoff either.
Theoretically, the gubmint should love Ecigs because die-hard smokers like me finally quit making smoke clouds. But we must have more rules. So, they are in conflict with themselves. Idiots.
