MOST teachers have no idea how to handle drug abuse among pupils, while Government-sponsored anti-drug campaigns are inadequate, a welfare organisation said. The study by the Boys' and Girls' Clubs Association also found a 'worrying' trend which suggested young abusers might not necessarily be triad-related, but 'average students' trying to escape boredom. The case study of 13 young drug abusers between 15 and 17 years of age also shows most take more than one type of drug, with one taking more than five types. All had heard of heroin, cannabis and cough syrup while more than half took No 4 heroin, a variety which has dropped 20 per cent in price in the past year. The study which also covered teachers, parents of drug abusers, and social workers, shows the Government needs to review its anti-drug campaigns, whose effectiveness was questioned by most respondents. Training should also be provided to teachers to improve their knowledge of drugs, and on how they should handle drug abuse. Interviews conducted with four teachers show they knew little about drugs and their impact on health. Most have little understanding of the methods and resources for treatment. They generally feel helpless, worried and the consider the issue troublesome when their students become drug abusers. The findings came as the Government's Narcotics Division revealed its quarterly figures on young drug abusers, which showed a 35.7 per cent increase from 1,050 to 1,425 over the same period last year. It also noted an increase in new admissions in the under-21 age group to the Methadone Treatment Programme. The number has grown 128.7 per cent from 95 to 215. Association director Justina Leung Ngai Mou-yin yesterday criticised the Government's anti-drug publicity in the form of carnivals and concerts, claiming most social workers consider them a waste of resources. She said the Government should target classrooms, producing teaching kits so teachers and social workers could be better informed. 'In this past year, we are seeing more young drug abusers and cheaper drugs such as No 4 heroin on the market. 'The young drug abusers may not necessarily have a triad background. They may be normal students who get their drugs from friends, clinics and chemists.' Mrs Leung said urgent ways should be identified to stop the supply of both hard and soft drugs, and the Department of Health should step up surveillance on clinics and chemists. The Commissioner of Narcotics, Alasdair Sinclair, said while the Government would introduce immediate programmes to deal with the problems of drug abuse among young people, it would take two years to see whether they had an impact. He also said the Government's campaigns might not be working for everyone, but should have some effect, adding he welcomed suggestions on how they could be conducted.
