A MARANGAROO teenager has pleaded guilty to twice being found with illicit drugs in the Dunsborough Leavers Zone in November.
Nelson Robert Summers admitted having possession of MDMA inside the zone on both the Wednesday and Thursday nights of the Leavers' week.
The Busselton Magistrates Court heard on Tuesday that a plain clothed police officer spotted the 18-year-old being passed three MDMA pills on the dancefloor on Wednesday, November 25.
He was arrested, evicted from the zone and charged by police after admitting he paid $105 for them.
Police prosecutor Sergeant John Mawson told the court Summers was interviewed by officers and said "they make him feel better and cause him to have more fun".
When Summers returned to the zone the following night, Thursday, November 26 , he was stopped by security staff at the entrance.
A search found two more MDMA tablets in a clip-seal bag in his wallet.
Summers told police has was "holding them for a mate".
Magistrate Dianne Scaddan told defence lawyer Michael Laurino he would have a hard time convincing her Summers deserved a spent conviction.
"He clearly didn't learn the lesson the first time," she said.
Summers was referred to the pre-sentencing opportunity program for drug counselling and will return to Busselton Magistrates Court to be sentenced on February 9, 2016.
