Are most Latino smokers in California low-frequency smokers?
The fact that most Latino smokers are low-frequency smokers calls for a new theoretical framework--beyond withdrawal-based theories--to account for the prevalence of this behavior on the population level. It also calls into question the harm-reduction approach as a tobacco control strategy for California Latino populations. Strategies emphasizing that every cigarette can hurt, and encouraging complete cessation, seem more fitting for this group of smokers.
