A campaign which aims to cut the number of adults buying alcohol for under-age teenagers has been launched.
Off-licences and adults who buy drink for under-18s will be targeted
The "Do Us a Favour...?" campaign in Glasgow is an initiative targeting adults who buy alcohol for people under 18 and off-licences who sell to them.
NHS Greater Glasgow said 25% of 12 to 15-year-olds get their alcohol from an older person.
The poster campaign will target Easterhouse, Greater Pollok, north Glasgow, Drumchapel and the east end.
It will be run by NHS Greater Glasgow in conjunction with Strathclyde Police and other local prevention projects.
Health staff and police will work closely with off-licences and alcohol outlets throughout the campaign.
Nikki Boyle, health promotion officer with NHS Greater Glasgow, said: "Alcohol use amongst young people is a huge problem in Glasgow and it's being made worse by older people obtaining the drink for youngsters.
"Young people's drinking in Glasgow is on the increase and part of that is due to the ease at which young people can access alcohol. For many, it's often as simple as getting an older person to buy it for them.
"That raises a number of concerns about the detrimental affect that alcohol has on the health of the young people and there's also a lot of concern amongst several Glasgow communities about public disorder and anti-social behaviour caused by drunken teenagers."
The aim of the campaign is to reduce the number of adults buying alcohol for under 18s by reinforcing the message that it is against the law and that anyone doing it risks a fine of up to £1000.
The campaign also aims to remind off-licence staff that they also have legal responsibilities and obligations.
The campaign was recently piloted in East Renfrewshire in partnership with NHS
Argyll & Clyde and Strathclyde Police.
