Police have issued a summons for Sek Loso to report to Kannayao police station in Bangkok on Jan 12 to be formally charged with drug use.
Kannayao police chief Pol Col Sing Singhadej said on Thursday the summons was delivered by hand to his house in Bang Khen district, Bangkok.
The summons was issued after a sample of the rock star's urine tested by the Institute of Forensic Science at Police General Hospital showed positive for methamphetamine.
Police will request the Min Buri Provincial Court to revoke his current bail if he does not turn up on Jan 12, Pol Col Sing said.
The embattled performer was earlier taken to Kannayao police station on Sunday and charged with resisting police in the performance of their duty when they went to his house to arrest him for firing gunshots into the air in front of the statute of King Taksin the Great at Wat Khao Khun Phanom in Phrommakhiri district in Nakhon Si Thammarat last Friday.
Phrommakhiri police have charged him with unauthorised possession of a firearm and firing shots in a public place. He denied another charge of illegally obtaining a pistol.
The Nakhon Si Thammarat Court granted him bail on Wednesday.
Sek, whose real name is Seksan Sookpimay, posted a message on his Facebook account on Thursday asking that people stop getting worked up about the charges.
"Everybody should stop talking about it. It's just a small matter. We should be thinking about how to develop the country, make people's lives better and improve the media," he wrote.
His page showed he was still in the southern province on Thursday.
His lawyer, Mongkolvijit Dhanasophon, told INN news agency Sek had been informed of the police summons and his client would report to Kannayao police station on Jan 12.
