A chemistry teacher surnamed Liang in Taoyuan joined a drug manufacturing ring, where he taught drug-making techniques and purchased necessary raw materials and equipment. Police raided the factory in September 2023, seizing approximately 200 kilograms of finished and semi-finished Class 3 drug "Meow Meow" (Mephedrone). Despite Liang's claims of ignorance, the courts found evidence that he actively helped solve chemical reaction problems and deemed him indispensable to the operation. The Supreme Court recently rejected his appeal, finalizing his sentence at 7 years and 9 months in prison.
