A beauty queen from Thailand who was among the 20 finalists in this year's local Miss Maxim competition has been disqualified by the publication after a video emerged showing her teaching a five-year-old boy how to snort a substance believed to be Ketamine.

Kwanjai Khempradub took to her Facebook page shortly after the video began making the rounds to deny that the powder being inhaled by the boy in the video is Special K (known locally as K or Ya K).

Kwanjai agreed that she behaved inappropriately, but insisted the substance was merely harmless baby powder — a claim Thai netizens quickly dismissed.

Her relations to the child remains unclear.

Irrespective of the powder's true nature, Kwanjai still faces a charge of violating the country's Computer Crime Act, which prohibits the production of videos that could teach others how to use drugs.

Police have asked Kwanjai to come forward and submit herself to a criminal investigation.

"If she doesn't come on her own, we will issue a summons. If she does not respond, she will face an arrest warrant," said Technology Crime Suppression Division chief Maj-General Pisit Pao-in.

If convicted of a drug crime, Kwanjai could spend up to five years behind bars.

A police spokesman added that sharing the video online is itself a jailable offense.
