Description
Measurement to ascertain when the respondent quit smoking. Response is used to calculate duration of use and pack-years measures and allows one to distinguish recent quitters from long-time quitters.
Specific Instructions
Respondent is asked how long it has been since he or she smoked and how old he or she was when he or she last smoked only if he or she answered "yes" to the first question of the Tobacco - Smoking Status (Adolescent Protocol).

Selection Rationale
The protocol from the National Survey on Drug Use and Health (NSDUH) was selected because this survey is the primary combined source of information on the use of drugs, alcohol, and tobacco in the civilian, noninstitutionalized population of the United States. The study was initiated in 1971, and it is currently conducted on an annual basis. The NSDUH is a survey that includes all substance use and that is administered to individuals age 12 and older. This survey asks many additional questions that may be more relevant to investigators studying adolescent subjects.
