South Central Connexions, a Government-funded youth information and advisory service, is working with advisory service No Limits to produce an alcohol awareness campaign, called 'think B4 U drink'.
The campaign aims to cut the number of youngsters who binge drink and asks parents if they know where their children are.
Posters highlight the issues young people face when they drink too much alcohol, appearing across the city in bus shelters, schools and youth venues.
The posters will be themed on the dangers of unprotected sex, sexually transmitted diseases, anti-social behaviour and vandalism.
A group of students from a local school are also performing a play about the dangers of drinking.
