It was highlighted that the in the original article [1] in Table 1 and Table S3, the labels for the "Poverty level" variable (Below 100% threshold, At or above 100% threshold) were presented in the incorrect order. That is, label "At or above 100% threshold" should have appeared first. Also, in the Results section, the following sentence should have appeared as: "Exclusive current SLT users, along with exclusive current and former smokers, were more likely to be non-Hispanic white and have less education (less than high school or high school diploma) and higher poverty level (at or above 100% poverty threshold)." The original article has been updated.
