Northern Ireland medics on the drug abuse frontline

The Mater Hospital's emergency department deals with about 30 drugs-related cases every day, with children aged 14 being treated for cocaine use.
In some cases patients are presenting with acute psychosis.
In others, they have attempted to take their own lives.
Dr Aisling Diamond, consultant in emergency medicine at the Belfast hospital, believes the situation will get "an awful lot worse".
"I can't recognise Belfast as the city I grew up in," she said.
