Thomas Warrick was arrested in Rochford on 1 December last year after drugs marketing messages were linked back to his phone number. He had £480 cash on him and the phone used by the Maxwell drugs line, which supplied cocaine and heroin in the Southend area.
The 29-year-old admitted being concerned in supplying cocaine and heroin, and acquiring, using or possessing criminal property when he appeared at Basildon Crown Court on 6 January.
