The following appeared in the editorial section of a newspaper.

“As public concern over drug abuse has increased, authorities have become more vigilant in their efforts to prevent illegal drugs from entering the country. Many drug traffickers have consequently switched from marijuana, which is bulky, or heroin, which has a market too small to justify the risk of severe punishment, to cocaine. Thus enforcement efforts have ironically resulted in an observed increase in the illegal use of cocaine.”

22. 报纸的社论：
由于公众对滥用药物的情况越来越关注，权威人士更警惕地(vigilant)防止非法药物进入国内。许多毒贩子(traffickers)已经从大体积的大麻和市场太小因而风险很高的海洛因转向了可卡因。监管的努力讽刺性的导致了可见的非法使用可卡因的增长。

可卡因流行不是因为enforce

没有enforece情况会更糟糕

anymore??

1.作者提供的非法使用可卡因的增多和监管的努力似乎只在时间上是前后关系,而不一定有因果关系.

2.即便毒贩转向运进可卡因,但是吸毒者也不一定就一定能转变他们吸毒的对象.

3.评价监管的功效不能单独从一种毒品的使用情况来看.即使可卡因的使用确实增加了但是其他两种的使用却减少了,所以从总体来看监管还是有效的.

再补充：

1.限制进口illegal的cocaine不等于防止药物滥用

2.何为药物滥用有时候很难定义，因为cocaine还可以在止痛麻醉等方面有用
