Based on the lowest BIC, we derived six smoking trajectory groups as follows: Group 1 (22.05%, never smokers), Group 2 (11.16%, former smokers), Group 3 (12.75%, new current smokers), Group 4 (20.22%, decreasing light smokers), Group 5 (29.52%, steady moderate smokers), and Group 6 (4.30%, steady heavy smokers)
I had some difficulty lighting it, but after it caught on it smoked cooly and steadily without gunk
Additionally, it can also make it harder to treat these conditions effectively
If using a match, let the sulfur burn off for a few seconds first to avoid getting a mouthful of match taste
Data on current smoking prevalence are presented in Appendix Figure A2
