Three new drug charges laid against ABC journalist Peter Lloyd in Singapore include one count of possessing utensils that carried traces of the veterinary drug ketamine.

Nicknamed Special K, ketamine is also a recreational drug used for its psychedelic or hallucinogenic effects.

The other two new charges against Lloyd are methamphetamine consumption without authorisation, and possessing utensils that carried traces of methamphetamine, a charge sheet shows.

The consumption charge carries a maximum penalty of 10 years in jail or a $S20,000 ($A15,400) fine, or both.

The other two charges each have a maximum penalty of three years in jail or a $S10,000 ($A7,700) fine or both.

The three new charges relate to events on July 16, the day of the ABC South Asia correspondent's arrest while on leave in Singapore.

Lloyd, 41, was grim-faced as he appeared briefly in the Singapore Subordinates Court and was told of the three new charges.

Amendments have also been made to the two original charges laid against Lloyd of possessing and trafficking methamphetamine, or ice.

It is alleged that on July 9 at Singapore's York Hotel, he sold a packet containing 0.15 grams of methamphetamine to a person identified as Sani bin Saidi for $S100 ($A76).

The charge carries a maximum penalty of 20 years in jail and up to 15 strokes of the cane.

The other amended charge alleges that Lloyd was found on July 16 to be in possession of a packet containing 0.41 grams of methamphetamine.

The maximum penalty on that charge is 10 years in jail or a $S20,000 ($A15,400) fine, or both.

Outside court, defence lawyer Tan Jee Ming confirmed the three new charges had been laid but said he wanted more time to study them before commenting.

But asked how serious they were, he said:"Comparatively, not that serious."

Lloyd, 41, wearing a blue and white checked shirt and black pants, said nothing as he stood before the judge, who extended his bail before adjourning the case for a week.

The New Delhi-based foreign correspondent was released on bail on Wednesday after being arrested last week while on leave in Singapore.
