More than 1,000 children were treated in hospital for drug and alcohol-related illnesses in 2019.
According to freedom of information figures, over 63 per cent were girls.
The conditions include drug or alcohol poisoning, a mental disorder due to substance misuse, and new-born children affected by their mothers’ use of drugs or alcohol.
1,026 children were treated for conditions such as these in hospital last year - down slightly from 1,101 in 2018.
A total of 762 were aged between 10 and 17 - with nearly twice as many girls as boys. 264 children were aged less than nine years old.
The total number of kids treated for drugs and alcohol-related illnesses in hospital is spread throughout the country - but nearly a third were in children's hospitals.
