Amy Winehouse's friends are urging her to return to rehab because they are afraid that the singer is slowly going back to her old ways.
The 24-year-old troubled pop star's pals have watched her since she left a clinic earlier this month.
According to the friends, Winehouse is undoubtedly on drugs and a full-time residential rehab is the only option left for her.
The singer's jailed husband Blake Fielder-Civil has even threatened to ban her from visiting him because he is sure that she is still taking crack cocaine.
"Amy's in an awful state again — she's clearly on drugs. Many of us think full-time residential rehab is the only option but she won't go back," The Sun quoted a friend, as saying.
Winehouse has a history of self-harming while high on drugs - she displayed mystery marks and spots on her knuckles and hands when she went out to the shops in London this week and bought kids' sweets.
Winehouse left rehab to perform at the Grammys via satellite from London two weeks ago.
However, a source has revealed that the pop star has been taking drugs ever since she walked out of rehab.
"She was smoking cannabis and drinking heavily as soon as she left rehab. That has now increased," the source said.
"Everyone who's seen her in the last week or so has been really disturbed by the state she's in. She's getting back to her worst.
"It was hoped her new album and fashion range would keep her focused but it hasn't worked," the source added.
