72% of teenagers treated for addiction in west Dublin reported a problem with cannabis.

This is according to a report by the HSE Adolescent Addiction Service in Ballyfermot that found cannabis was the substance most used by their patients last year.

The service, based in Cherry Orchard Hospital, provides addiction treatment services for alcohol and drug abuse to young people from Ballyfermot, Clondalkin, Palmerstown, Lucan and Inchicore.

In 2018 it treated 43 teenagers between 13 and 18 and their families.

Their latest annual report shows that 70% of patients were also taking alcohol, with 36% using cocaine and 30% amphetamines.

Benzodiazepines were a problem for 12%, with ketamine (7%) and LSD in (5%) the two least abused drugs.

A spokesperson for the HSE said: “As in previous years, most young people had established patterns of substance use prior to referral and, as a consequence, some struggle to maintain drug-free status but most achieve stability and several remain abstinent.”
