A post mortem examination will be carried out today on the body of a Cork teenager who died after taking a synthetic drug at a house party last week.

18-year old Alex Ryan had been critically ill in Cork University Hospital since last Tuesday morning but life support was switched off on Saturday and he passed away in the hospital's Intensive Care Unit.

It’s expected that toxicology tests taken at post-mortem may take a number of weeks to confirm the exact form of the synthetic drug consumed by Mr Ryan at a house party in Cork city.

Investigating gardai believe that Mr Ryan took ill after he snorted a powdered form of a psychedelic phenethylamine derivative, I25I-NBOMe which has a street name of N Bomb.

Mr Ryan was a past pupil of Millstreet Community School and grew up in the North Cork town after his mother moved there from the Ukraine in the 1990s and settled in the area.
