For sample adults age 18 and over who have ever smoked a pipe at least 50 times in their life, PIPENO reports the number of units corresponding to the length of time the respondent smoked pipes. Responses were categorized into "less than one month," or a numeric value for the number of months or years.


The Field Representative's Manual instructed interviewers to probe to determine the best approximate values. For example, if the respondent reported, "on and off for 20 years," interviewers would probe to determine the total number of years, excluding the off periods.

The term pipe was respondent-defined. The Field Representative's Manual for 1987 mentions if the question arises, interviewers should include pipe tobacco only, and cigarette or cigars crumbled into pipes should not be counted.
