　　But such policies seem instead to have created the conditions for even more campus violence.Some college students who previously drank in bars and lounges under the watchful supervision of bouncers (not to mention owners eager to keep their liquor licenses) now retreat to the sanctuary of their fraternity houses and apartments, where they no longer control their behaviour or their drinking.The boomerang effect has also played a role in attempts to reduce the availability of illicit drugs.During recent years, the federal government has been quite successful in reducing the supply of street drugs.As fields are burned and contraband confiscated, the price of street drugs has skyrocketed to a point where cheap altematives have begun to compete in the marketplace.Unfortunately, the cheap alternatives are even more harmful than the illicit drugs they replace.

　　同樣取得適得其反的效果。近年來(lái)，聯(lián)邦政府成功遏制了街頭毒品買(mǎi)賣(mài)。警方摧毀了許多毒品種植園，沒(méi)收了違禁品，導(dǎo)致街頭毒品買(mǎi)賣(mài)的價(jià)格暴漲。因?yàn)榱畠r(jià)毒品作為替代品開(kāi)始有了競(jìng)爭(zhēng)力。更糟糕的是，那些廉價(jià)的替代品比之前的毒品危害更大。
