This article is intended to give an overview of several arguments for and against drug prohibition. Efficiency Drug laws are effective Supporters of prohibition claim that drug laws have a successful track record suppressing illicit drug use since they were introduced in the 1910s. The licit drug alcohol has current (last 12 months) user rates as high as 80–90% in populations over 14 years of age, and tobacco has historically had current use rates up to 60% of adult populations, yet the percentages currently using illicit drugs in OECD countries are generally below 1% of the population excepting cannabis where most are between 3% and 10%, with six countries between 11% and 17%. In the 50-year period following the first 1912 international convention restricting use of opium, heroin and cocaine, the United States' use of illicit drugs other than cannabis was consistently below 0.5% of the population, with cannabis rising to 1–2% of the population between 1955 and 1965. With the advent of the counter-culture movement from the late 1950s, where illicit drug use was promoted as mind-expanding and relatively harmless, illicit drug use rose sharply. With illicit drug use peaking in the 1970s in the United States, the "Just Say No" campaign, initiated under the patronage of Nancy Reagan, coincided with recent (past month) illicit drug use decreases from 14.1% in 1979 to 5.8% in 1992, a drop of 60%. In March, 2007, Antonio Maria Costa, former executive director of the United Nations Office on Drugs and Crime, drew attention to the drug policy of Sweden, arguing: In Europe as of 2007, Sweden spends the second highest percentage of GDP, after the Netherlands, on drug control. The UNODC argues that when Sweden reduced spending on education and rehabilitation in the 1990s in a context of higher youth unemployment and declining GDP growth, illicit drug use rose but restoring expenditure from 2002 again sharply decreased drug use as student surveys indicate. In 1998, a poll run by SIFO of 1,000 Swedes found that 96% wanted stronger action by government to stop drug abuse, and 95% wanted drug use to remain illegal. Criticizing governments that have relaxed their drug laws, Antonio Maria Costa, speaking in Washington before the launch of the World Drug Report in June 2006, said: Inefficiency Drug laws are ineffective One of the prominent early critics of prohibition in the United States was August Vollmer, founder of the
