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.”
Discuss how well reasoned . . . etc. 我就想出来一条：在非法进口毒品总量不变的情况下，cocaine使用会增多，但这里的严格控制使得总量很有可能会变小，所以不能得出cocaine 的非法使用总量会增加。 作者: yaobinmei 时间: 2012-3-8 14:00
