	B	SE (B)	95% CI Lower	95% CI Upper
Regular smokers
Total indirect effect (both mediators)	−.10	.03	−.16	−.04
Indirect effect mediated through COT	−.08	.03	−.15	−.03
Indirect effect mediated through CPD	−.02	.02	−.06	.01^*
Intermittent smokers
Total indirect effect (both mediators)	−.02	.01	−.05	.008^*
Indirect effect mediated through COT	−.02	.01	−.05	−.002
Indirect effect mediated through CPD	.01	.01	−.02	.03^*

No indirect effects as the 95% CI includes a zero value.
