Monitoring other tobacco product sales in conjunction with the monitoring of e-cigarette sales is necessary to provide a comprehensive picture of the overall U.S. tobacco product market. These data briefs provide estimates of tobacco product sales in the U.S. market overall and select U.S. states. These retail sales data briefs are intended to provide information about population trends in tobacco product sales for participating retailers; they do not include online sales or tobacco specialty store sales and cannot be used to make conclusions about subgroup purchasing or behaviors. These estimates are based on the information available at the time of publication and may be subject to updates as more information becomes available.
