Smokers can no longer light up in bars across Northern Ireland as the new smoking ban has come into force.
It is now illegal to smoke in workplaces, most enclosed public spaces and on public transport. The ban will be enforced by local councils.
Smoking is said to cause 3,000 deaths in NI each year, with one death every fortnight due to second-hand smoke.
The Republic of Ireland, Scotland and Wales already have smoking bans in place; England's starts on 1 July.
