Bang Lamung district police and municipal officials descended on the Burn Club on Soi Bua Khao at 4am checking for underage patrons and evidence of drug use.
Kannikar, 24, who has more than 200,000 followers on Facebook and was working at the club as a DJ, was among six people whose urine tests showed signs of drug use.
She reportedly confessed to police that she had taken ketamine three days earlier.
Club manager Anapat Reung-urai, 50, was charged with keeping the club open too late, operating without a permit and selling alcohol beyond the legal time period.
