Limerick Coroners Court heard what was described as “serious stuff” was found on the Facebook page of the 21-year-old student.
Fellow students were in their apartment on February 8 last and were getting ready to take part in a rag week event.
One went to the room of the student and saw him near the door. However, on entering, the occupant was lifeless.
The emergency services were called and attempts at CPR were unsuccessful.
A medical report showed blood and urine samples contained traces of ecstacy and cannabis.
The student died from asphyxia.
A relative of the student told coroner John McNamara that she looked at his Facebook page and found it contained “serious stuff”.
She said she would be very concerned with the kind of communication he had with another person.
The coroner said there were some drugs in the student’s system and this could have affected the young man’s decision-making capacity.
Accordingly, the coroner said he felt it appropriate to record an open verdict.
The inquest also dealt with two other cases.
An open verdict was also recorded into the death of another 21-year-old man whose body has never been found.
The man was last seen on January 10, 2009, entering water from the Shannon Bridge in Limerick. Two people witnessed the man go into the river.
Major search operations were conducted over a period of weeks involving marine river rescue teams, and also a coast guard helicopter.
Meanwhile, a verdict of misadventure was recorded into the death of a 34-year-old mother who died while seated in her sitting room.
After her partner put their young child to bed, he was unable to awake her. Efforts to revive her failed.
A pathologist’s report found she died from high levels of a prescribed drug.
The coroner told the woman’s family the medical report indicated she had passed away in her sleep and did not suffer.
He was satisfied the woman did not intend to die and recorded a verdict of misadventure.
