校本驗毒唔止唔work,還會有反效果

看到政府不理各方反對一意孤行要推校本驗毒,但又唔敢做得太盡,話學生如果不同意也可不驗,不禁啼笑階非;就好似有人要黎強姦你,但話定你知你唔同意佢都可以唔入你!一方面好想冷眼旁觀看這場鬧劇,另一方面又不忍看到學生對學校、家長以至政府僅餘的互相給磨滅掉。

練乙錚昨天那篇文章, 已清楚說明根據外國經驗校本驗毒係唔work的,他提到的其中一篇研究前兩天我剛巧download了,到這裡補充一下。這個由University of Michigan 的Yamaguchi, Johnston and O'Malley作的研究,比較有作校本驗毒的學校與沒有的學生吸毒率,發現兩者分別不大,即是說校本驗毒未能起到壓止學生吸毒的作用。

"There are still no significant differences in marijuana use or the use of other illicit drugs as a function of whether or not the school has (a)drug testing of any kind, (b) drug testing of students based on cause or suspicion, or (c) drug testing of athletes. Nor is there evidence that the heavy drug-using segment of the student population, specifically, is deterred from using marijuana or other illicit drugs by random or for cause testing."

更令人憂慮的,是研究指出有作校本驗毒的學校的學生吸食大麻以外的毒品比率,竟比沒有驗毒的學校的學生更高!其中一個原因可能是學生減少吸食他們認為能被驗出來的大麻,轉而吸食其他他們認為不會被驗出來的其他毒品。

"One could generate hypotheses to explain such a phenomenon, such as that testing leads students to reduce their use of drugs that can be detected (like marijuana) and to displace their use onto drugs that they think less likely to be detected."

校本驗毒勞民傷財(一次要百多元),為何不把資源投向社會服務幫助需要幫助的人?
