More people here use E-cigarettes or similar than anywhere else in the country.
24% of people in Yorkshire use e-cigarettes - the highest percentage in the country.
But two-in-five find those who use vapers inconsiderate and annoying, according to new research. Half admitted to being confused over vaping rules.
Someone in the UK switches to using a vaper every four minutes and there are now 2.2 million users.
Katherine Lewis, from Debrett's, told Pulse 1 & Pulse 2: "It has only been the last five years that it has become mainstream, but it is now about opening a dialogue as to what is acceptable and not - especially as there are no official guidelines.
"The big no's are vaping in a confined space - like lifts and cars. The other one is vaping in a restaurant.
"And there needs to be just general awareness. Don't just blow vape clouds into someone's face!"
The top 10 faux pas, which are dragging down puff politeness, are:
1. Vaping in a confined space
2. Vaping in a restaurant
3. Vaping during a job interview
4. Blowing vapour in someone's face

6. Vaping in a queue
