Establishing a standard measure of blunt and cigar use for U.S. national surveys

Abstract

Background

Researchers have drawn attention to the need for modifying survey questions on cigars for distinguishing use intended for tobacco versus cannabis (i.e. blunt) consumption. Yet, most surveys do not distinguish persons who only smoke blunts (POSB) from persons who smoke blunts and unmodified cigars/cigarillos (PSBC). This study was intended to evaluate existing measures in U.S. national surveys for establishing a standard for the field.

Methods

Two of six leading U.S national surveys, the NSDUH and PATH, measured dual use of blunts and cigars. The analytical sample of this study included adult participants of the 2017 NSDUH (n = 2493) and Wave 4 PATH (n = 3175) who smoked a cigar or blunt in the past month and reported cigar brand usually or last smoked; the latter was used as a validation measure.

Results

Odds of using Swisher Sweets and other brands (vs. Black & Mild) increased with more frequent blunt use relative to persons who only smoked unmodified cigars/cigarillos (POSC). Further, regression coefficients for the three subgroups of PSBC differed significantly, highlighting the utility of an ordinal versus aggregated measure. Estimates of the former were diminished in magnitude upon expanding the sample to persons who smoked any cigar product.

Conclusions

Validation of the ordinal measure of blunt-cigarillo use in PATH supports the measure’s implementation as a standard for U.S. national surveys. Implementation of the measure in other surveys (e.g., NSDUH) would provide a more consistent and accurate assessment of blunt and cigar use for monitoring health risks.
