(Violent Crime and Substance Use) "Contrary to conventional wisdom and popular myth, alcohol is more tightly linked with more violent crimes than crack, cocaine, heroin or any other illegal drug. In state prisons, 21 percent of inmates in prison for violent crimes were under the influence of alcohol--and no other substance--when they committed their crime; in contrast, at the time of their crimes, only three percent of violent offenders were under the influence of cocaine or crack alone, only one percent under the influence of heroin alone."
(Leading Causes of Death 2000) "The leading causes of death in 2000 were tobacco (435,000 deaths; 18.1% of total US deaths), poor diet and physical inactivity (400,000 deaths; 16.6%), and alcohol consumption (85,000 deaths; 3.5%). Other actual causes of death were microbial agents (75,000), toxic agents (55,000), motor vehicle crashes (43,000), incidents involving firearms (29,000), sexual behaviors (20,000), and illicit use of drugs (17,000)."
(Illicit Substance Use by 'Lifetime' Alcohol Users in the US) "Lifetime alcohol users aged 21 or older had a significantly higher rate of past year illicit drug use (13.7 percent) compared with lifetime nondrinkers (2.7 percent). In addition, lifetime alcohol users had significantly higher rates of past year use across all illicit drug categories, with the exception of inhalants (Table 1). Nonmedical use of pain relievers was the illicit drug used most often by lifetime nondrinkers, whereas lifetime alcohol users reported using marijuana most frequently."
('Lifetime' Alcohol Users and Other Drug Use) "In 2002 and 2003, an estimated 88.2 percent of persons aged 21 or older (175.6 million) were lifetime alcohol users, whereas an estimated 11.8 percent (23.5 million) were lifetime nondrinkers. Over half of lifetime alcohol users (52.7 percent) had used one or more illicit drugs at some time in their life, compared to 8.0 percent of lifetime nondrinkers.
