We've learned Steven Adler -- former drummer for Guns 'N Roses -- has been busted (again) on a drug charge.
Cops tell us Adler was arrested on Jan. 26th and charged with being under the influence of a controlled substance -- a misdemeanor. We don't know the exact substance.
We're told Steven was released the same day at 10:50 AM on $50,527 bail (weirdest amount we ever done seen). No court date has been set.
Adler was busted last July for possession of narcotics, being under the influence and for an outstanding warrant -- and was ordered by the court to stay at the Pasadena Recovery Center.
UPDATE: 6:22 PM ET Steven's people say he was arrested because he hadn't finished his community service in the time frame given by the judge. They say Adler went to register as a drug offender -- also court ordered -- on the 26th, when cops acted on the arrest warrant stemming from the unfinished community service. He was charged with "being under the influence of a controlled substance" because that was the original charge from his July arrest.
Steven's people want to make it clear he was not under the influence of drugs.
