Hampshire Constabulary has joined forces with the county's pubs, clubs, schools, universities, local authorities and the Treetops Sexual Assault Referral Centre to educate and inform young people about the links between alcohol and sexual assault.
The campaign, which is primarily aimed at young people aged 15 to 24, has three main messages – responsibility, consent and look after your friends.
It will be using a DVD, schools' education package, posters and leaflets in pubs and clubs, university websites and Bluetooth messages near pubs and clubs at closing time to promote its safety messages.
Detective Inspector Tara Williams, a campaign leader, said the campaign is designed to make young people think about how short term actions can have long term consequences.
She added: 'When most people hear the word "rape" they tend to think of a stranger waiting in bushes and attacking women as they walk home late at night.
'The reality is far from this though, and most of the rapes reported to us involve people who are known to each other.'
Mary Bridgman, manager of Treetops, said: 'Alcohol can affect your judgement, make you lose your inhibitions, and mean you take risks.'
