The funeral mass of Keane Mulready Woods has heard a call for other teenagers not to be groomed by "ruthless criminals".
The 17-year-old's body parts were found in Coolock and Drumcondra last month, after he got involved with drugs gangs.
The priest at today's service said Keane's murder has caused an "unparalleled level of revulsion" across the country.
Father Phil Gaffney said he hoped Keane Mulready Woods' death would be a "wake up call".
Addressing young people tempted by crime and casual drug-users, he said "all our actions have consequences".
"Those who take drugs on a social basis have to realise they are fuelling this situation", he said.
Father Gaffney told those gathered that "doing a line of coke is as normal as having a drink nowadays".
