Harper, 19, of Glynhir Road, appeared at Swansea Crown Court charged with three drug offences.
The teenager was accused of being concerned in the supply of cocaine between April 8 and May 2 last year. Harper was also charged with possessing 1.21 grams of cocaine – worth approximately £120 – with the intent of supplying it on May 1, 2023. A third offence of possession of cannabis, also on May 1 last year was also admitted.
The defendant pleaded guilty to being concerned in the supply of cocaine and possessing cannabis. He denied possession with intent to supply cocaine.
The Crown Prosecution Service said these pleas were acceptable, and prosecutor Craig Jones said a trial would not be sought on the remaining charge.
Judge Geraint Walters ordered a pre-sentence report to be prepared, and set a sentencing date of June 21.
He granted Harper bail until that date, but warned him that all sentencing options remain open.
