"A guinea pig" drugs tester for a Gloucester gang has stayed off drugs and is making excellent progress with the probation service, a court heard.
Jason Danter, who admitted testing the quality of M-Cat for Reuben Brissett one of the city's drug ring leaders, in June.
The 43-year-old was given an 18-month community order with supervision, a thinking skills programme and a drug rehabilitation requirement and appeared back before the court on Tuesday for a review of his progress.
Judge Jamie Tabor QC said probation reports on Danter of Badminton Road, Matson, confirmed he had an excellent level of attendance and good feedback with the service.
The delighted judge told him: "This is not the Jason Danter I know."
Danter replied: "I am getting older and I have seen the light."
"If you can maintain this, it will be great for you, great for Gloucester and you will be less of a burden to this court," the judge told him.
"Are you proud of yourself?," he asked.
Danter replied: "Yes I am. I am keeping away from certain people."
Brissett, 33, of London Road, was jailed for a total of six-and-a-half years for leading the conspiracy to supply MCat, as well as another separate drugs ring to supply cannabis.
He joined his brothers Rodney and Micah behind bars, who are both also serving lengthy sentences for drug offences.
Danter will be back before the court again in another month for his next review.
