A man with a long standing addiction was frank with police about his time supplying drugs.
Wayne Bromley admitted dealing on one occasion, but his honesty with officers led to two further charges being put to him, Preston Crown Court heard.
The 38-year-old of King Edward Avenue, Blackpool admitted three charges of supplying drugs. Two of the offences related to heroin and the other involved cocaine being supplied to an undercover police officer.
David Clarke, prosecuting, said the defendant appeared to have been a “runner”.
Bromley accepted dealing about £200 worth of heroin and cocaine.
Defending Rachel Woods, said for many years Bromley had been struggling with drug addiction, but recently he had been making progress.
The case was adjourned for sentencing until November 28.
