No, not poisonous. It's the about the quantity and quality. Large quantities of the cheapest vodka you can get usually means that you are a hardcore alcoholic or you are on a serious mission to get as blasted as you possibly can in as short of a time as you can.
Not many people but large jugs of cheap vodka because they like the taste. (Some do, though.)
What is the comparison here? If both objects are in cold and dry conditions, I wouldn't expect any less.
If they had unwrapped the cigarette butt to expose the filter, it might have been a better representation of their point?
Maybe it's just a promotional cigarette ad for frogs? Math problem? frog + cigarette = frogarette? Yeah... I dunno.
