Not vaping in crowded and confined spaces
It’s challenging enough to dispel myths on a one-to-one basis, so imagine trying to explain the facts to a room full of people you don’t know, who just want to enjoy themselves. You aren’t going to have much luck, so vaping in a crowded or confined space is likely to lead to confrontation, being ejected from the premises, and - depending on the nature of the establishment - a fine.
