The opening of a new advice line for people with alcohol problems is the final part of a £2.1m NHS investment in Derby's alcohol treatment programme.
The confidential telephone helpline provides a gateway to the city's new programme, which has reduced waiting times from two years to three weeks.
About 9,000 Derby people are thought to be drinking harmful levels of alcohol, with another 6,000 dependant.
The programme, based in hospitals and the community, began in June.
Since the investment, waiting times are estimated at three weeks rather than the two-year waits previously experienced, according to Derby Community Safety Partnership and NHS Derby City.
Richard Martin, head of drug and alcohol strategy at Derby Community Safety Partnership, said: "Alcohol abuse can have a devastating effect on the individual, their families and friends, and the wider community.
"Families and communities who experience at first hand the problems associated with problematic drinking rightly expect alcohol treatment to be available to all those who need it. We believe the new alcohol treatment system will meet these requirements."
