Answer to Question 1
Methadone maintenance programs are highly controversial. Critics argue that they merely replace one addiction with another, which is true, and that many addicts return to heroin and other drugs.
There is also a black market in methadone supplied in part by addicts in treatment who sell rather than take their methadone, and some methadone addicts get high by taking nonopiates, such as cocaine, whose effects are not blocked by methadone.
Answer to Question 2
The effort to prohibit the use of alcohol through the Eighteenth Amendment to the U.S. Constitution was an abysmal failure. People continued to drink, and organized crime flourished by supplying bootleg liquor. The amendment also produced a certain cynicism toward law and government, as violations of the law were open and flagrant. The hypocrisy of the law was finally recognized by 1933 when the Eighteenth Amendment was repealed.
