A woman who learned from her former doctor husband how to make the drug known popularly as Ice was jailed for three years yesterday for passing on the method to two suspected drug traffickers. Wong Yin-chun, 44, had pleaded guilty in the District Court to two counts of doing an act preparatory to manufacturing a dangerous drug and one of money laundering. Sentencing her, Deputy Judge Abu Bakar bin Wahab rejected defence submissions that information about the drug-making process and material was easily available on the internet. Even with such information, he said, anyone wanting to make it needed to know details of the method, chemical process and quantities. Ice, or crystal methamphetamine, had a legitimate medical use but could not be manufactured, traded or inhaled on demand. The drug had to be handled in accordance with the law and a deterrent penalty was needed to protect the public. The court heard that Wong, who has a 12-year-old son, was arrested in January after an anti-graft investigation following a complaint. She told investigators she came to know a suspected drug trafficker early last year. She accompanied him to Vietnam and Laos to examine the drug-making. She admitted teaching two suspected traffickers how to make the drug, including providing information about the required equipment, ingredients and proportions. One of the suspected traffickers paid her HK$10,000 for going to Laos and she deposited the money in her bank account. The court heard that her husband, who had taught her how to make the drug, had died after they separated and she was now supported by her security guard partner.
