This 2002 report examines the state of substance abuse detoxification and the number and characteristics of patients who go on to substance abuse treatment after detoxification.  To assist patients in moving from detoxification to treatment, the report concludes that more information is needed on the range of detoxification programs and on processes at individual programs and systems levels. 

From the report:

In 2000, 12.6 million Americans were heavy drinkers (consuming five or more drinks in one sitting), and 14 million Americans were using illicit drugs (Office of Applied Studies 2001). Overall, fewer than one-fourth of those needing treatment receive it (Schneider Institute for Health Policy 2001). Each year, at least 300,000 patients with substance use disorders or acute intoxication obtain inpatient detoxification in general hospitals; additional numbers obtain detoxification in other settings.
