The Justice Department is seeking outside expert help on the addictiveness of ketamine to help a court sentence a 19-year-old drug trafficker. Mr Recorder Ronny Wong Fook-hum, SC, yesterday adjourned sentencing of Lee Wai-man, 19, until September 8. Lee pleaded guilty in the Court of First Instance to trafficking in a dangerous drug. Prosecutor Daniel Ozorio said Lee was found with 1,619 tablets - containing a total of 187.83 grams of ketamine and 27.94 grams of methamphetamine - when he was intercepted at the arrival hall of Lowu Control Point on his way back from Shenzhen on February 24. Defence counsel Giles Surman said an analysis of the tablets by a government chemist had found the pills contained both ketamine and methamphetamine, a derivative of the drug commonly known as 'ice'. He said it was important to clarify the distinction between ice and Ecstasy because if his client was sentenced for Ecstasy, he was looking at a jail term of between two and four years - compared to the seven to 10 years laid down for ice.
