It's now more than seven years since smoking became illegal in enclosed public places and workplaces in Scotland.

The smoke-free law aims to protect people from the harmful effects of passive smoking. Sanctions include fines for the smoker and for those in charge of premises if there is a breach of compliance or lack of display of appropriate signage.

 Then, in October 2007, the age which tobacco could be purchased increased from 16 to 18 in Scotland.
