How Federal Surveys Estimate the Prevalence Of Substance Use Disorders

"Illicit drug use disorder is defined as meeting DSM-IV criteria for either dependence or abuse for one or more of the following illicit drugs: marijuana, cocaine, heroin, hallucinogens, inhalants, methamphetamine, or prescription psychotherapeutic drugs that were misused (i.e., pain relievers, tranquilizers, stimulants, and sedatives). There are seven possible dependence criteria for specific illicit drugs:
"1. spent a lot of time engaging in activities related to use of the drug,
"2. used the drug in greater quantities or for a longer time than intended,
"3. developed tolerance to the drug,
"4. made unsuccessful attempts to cut down on use of the drug,
"5. continued to use the drug despite physical health or emotional problems associated with use,
"6. reduced or eliminated participation in other activities because of use of the drug, and
"7. experienced withdrawal symptoms when respondents cut back or stopped using the drug.
"For most illicit drugs, dependence is defined as meeting three or more of these seven criteria. However, experiencing withdrawal symptoms is not included as a criterion for some illicit drugs based on DSM-IV criteria. For these substances, dependence is defined as meeting three or more of the first six criteria.
"Respondents who used (or misused) a specific illicit drug in the past 12 months and did not meet the dependence criteria for that drug were defined as having abuse were defined as meeting the abuse criteria for that drug if they reported one or more of the following:
"1. problems at work, home, and school because of use of the drug;
"2. regularly using the drug and then doing something physically dangerous;
"3. repeated trouble with the law because of use of the drug; and
"4. continued use of the drug despite problems with family or friends."
