The benefits of giving up smoking include the immediate reduction of harm to the health of the smoking and easily admission to social activities and institutions that ban smoking. In a 1988 report, the U.S. Surgeon General declared cigarette smoking to be more harmful and expensive than the use of cocaine(可卡因) , alcohol, or heroin. Recent evidence supports this claim. The United States government has collected a special tax on cigarettes for several decades. The rate rose from 8 cents per pack of 20 cigarettes in 1951 to 24 cents per pack in 1993. In other developed countries, the cigarette tax rate is much higher, ranging from 50 percent in Switzerland to 85 percent in Denmark. In the United States, the first direct action to check smoking was the regulation of a warming on cigarette packages by the Federal Trade Commission. This warning took effect in 1964 and was strengthened in 1969 to read:“Warning: The Surgeon General Has Determined That Cigarette Smoking Is Dangerouis to Your Health.”In 1971 all cigarette advertising was banned from radio and television, and cities and states passed laws requiring nonsmoking sections in public places and workplaces. 第11题：Which of the following can help a person quit smoking？ A．Using nicotine patches.
