As a non-smoker who goes out five nights a week (first year of uni is fun
)I'm delighted by the ban.
And it'll be interesting to see how the ban will effect the dynamics of the nightlife. Smoking is a huge part of the clubbing/bar scene, whether you realise it or not. Not just the act of smoking (and lame guys asking for a light as a chat-up line
) but the smell of the place. It permeates everything.
Also, clubs will have to make arrangements for people to go outside the whole time to smoke. When half the people in the club are showing nicotine withdrawal symptoms it's not gonna do much for the atmosphere of the place!
