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
