While Scott Weiland undergoes yet another round of drug rehab, some of his fans and peers are questioning whether the troubled singer will turn his life around for the better this time.

"I wish I could say Scott will be able to knock off the drugs and make another STP album, but I think trying to quit heroin is like trying not to blink," wrote 15-year-old fan Rob Connor in an e-mail.

Other fans said that if rehab doesn't work this time, then maybe next time.

"I have faith he will [kick drugs] at some point," wrote 18-year-old Robin Klauss, who runs the website "Scott Weiland -- On His Own" (http://www.geocities.com/SunsetStrip/Stadium/9284). "David Bowie is one of Scott's biggest idols, and he's been clean for years now. Scott has to want it for himself; no one can force sobriety on him. That's the biggest factor to him sobering up."

Meanwhile, the singer's New York attorney, Bob Kalina, expressed optimism when asked if there's any reason for Weiland's fans to believe that this will be the singer's last visit to rehab. "We hope this will be different," he said Wednesday.

Kalina, who revealed to Manhattan, N.Y., Civil Court last week that Weiland recently had entered a treatment program, is representing the singer in a case involving his June 1 arrest in New York on heroin possession and trespassing charges. Weiland was found with $100 of heroin on the afternoon that he was scheduled to perform a sold-out show at the city's Irving Plaza nightclub. The arrest brought an early end to his first-ever solo tour in support of his debut solo album, 12 Bar Blues.

Kalina also was optimistic that the Stone Temple Pilots singer will attend a Los Angeles court hearing Wednesday to answer drug charges unrelated to his New York arrest. The singer is scheduled to appear in Los Angeles Superior Court to face charges of heroin and hypodermic-needle possession stemming from a September 1997 arrest.

Weiland, 30, whose court cases involving drug charges are continuing on both coasts, has made numerous trips to treatment centers during the last five years (including two this summer), leading at least in part to the current inactivity of STP, who have been on hiatus since early 1997.

As the platinum-selling rock band's wayward frontman gives rehab another go, shortly after telling SonicNet Music News that the band has begun talking about a new LP, many fans and peers say his return to treatment is an occurrence that is all too familiar.

"I think it's a big waste," said Jonathan Davis, vocalist of the thrash-rock band Korn. "The guy's got big problems. Heroin is a f---ed-up thing. He's had so many chances, I don't know what to say about the guy. Heroin's a bad drug. I've never been on it, but I've seen people f--- up their lives on it ... I predict him as the next rock-star death."

Davis also offered some insight into the pressures and circumstances that may have led to Weiland's drug problems. "It's easy to get sucked in and fall into that," he said. "When you're out on the road, everybody wants to take you out. You're a celebrity, it's f---ing party time, and it's hard not to self-destruct."

Police papers show that, during the New York arrest, Weiland told officers, "No, I do not live here; No, I'm not visiting anyone; I just bought drugs."

Weiland was excused from a hearing last week in New York based on Kalina's announcement, and that case was postponed until November.

Weiland has missed four hearings in the L.A. case, including one in June when he was undergoing rehab, according to his Los Angeles lawyer, Michael Nasatir. But after Weiland skipped a July 9 hearing for no apparent reason, Superior Court Judge Larry Fidler issued a bench warrant for his arrest. The singer was picked up nearly two weeks later and released on $250,000 bail.

Kalina would not reveal where Weiland is seeking treatment or how long he has been in the facility. "Scott really needs his privacy," he said. "I can't emphasize that enough."

Los Angeles District Attorney Penny Schneider, who earlier had said that Weiland's recent destructive behavior indicated that the singer is still a prisoner of his habit, said she was unaware that Weiland is again in treatment and would not comment on the matter until she has been notified.

Fan Felicia Marie Fairley, 17, of Mobile, Ala., wrote in an e-mail that she gives Weiland credit for at least trying to clean up. "I really do have faith in him," she wrote. "No matter what everyone else says. He is in rehab. He is trying ... All in all, I will always love Scott and I will continue praying for him."
