How do you react to e-cigarettes?

A poll carried out by BBC Breakfast has been gauging public attitudes to electronic cigarettes.

Increasing numbers of smokers have started using the cigarettes since the first ban on smoking in enclosed public places was introduced almost seven years ago.

The BBC's Graham Satchell has been asking shoppers how they feel about the use of e-cigarettes in public places, with e-cig smoker Katherine Devlin alongside him.
