The number of people in the southeast seeking help for heroin and cocaine addictions has increased.
The figures are part of a report which shows that alcohol abuse is still the reason why most people seek help at treatment centres.
Nearly 3,000 people in the five counties of the southeast covered by the report sought help for alcohol addiction, drug abuse or gambling problems last year.
The Health Service Executive says there was an increase of 115 people on 2006.
64% of people were treated for alcohol problems while cannabis addiction accounted for 12% of clients.
236 people, or 10.5%, were heroin users, while 154 people, or nearly 7%, had cocaine addictions.
The figures show that the number of people seeking treatment for alcohol and cannabis continues to be very high but has fallen slightly in recent years, whilst heroin and cocaine figures continue to rise.
