Gan Pei Hong, 21, who gave birth just two months ago, her husband Cha Wee Sang, 31, and Yap Yau Yang were alleged to have committed the offence at Taman Segar on June 5.
Yap also faced another charge of trafficking 98.4kg of heroin-based drugs at Taman Bukit Hijau, also in Cheras, on the same day.
No plea was recorded before magistrate Aina Azahra Arifin as the drug trafficking charge, which carries the death penalty or life imprisonment of up to 30 years, is only triable in a High Court.
All three were represented by T Harpal Singh. Aina Azahra set the case for mention on Aug 18.
The magistrate also rejected an oral application by Harpal to offer bail to Gan as she had medical problems during remand and that she had just given birth to a baby boy.
However, according to Harpal, Aina Azahra ordered Kajang prison authorities to send Gan to the hospital for a medical check-up.
Cha and Yap will remain in Sungai Buloh prison.
Kuala Lumpur police chief Azmi Abu Kassim was reported on June 11 as saying that the trio were active in drug distribution around the Klang Valley following the seizure of drugs worth RM9.3 million.
Five vehicles were also seized during the raids.
