Pete Doherty is vowing to stay off drugs, and an English court no longer feels the need to monitor that promise.
Doherty, 28, a musician best known as Kate Moss's ex-boyfriend, was released on Wednesday from a drug treatment order in the U.K., ending 18 months of court supervision, the Associated Press reports.
Outside the courtroom, Doherty, who has run afoul of the law with numerous drug offenses, told reporters he intends to stay clean. "It's just the beginning, you know what I mean? My life has changed," he said.
A close friend of the rocker told PEOPLE, "He's really really got his s--- together. His is a dry tour and he hasn't got his beer goggles on."
Doherty, who checked into rehab
in August, recently got engaged
to singer-model Irina Lazareanu, according to reports.
