Rodu’s research focuses on the substitution of safer tobacco products by smokers who are unable or unwilling to quit smoking with conventional cessation methods because of their addiction to nicotine. His research in comparative epidemiology established the scientific foundation for harm reduction and he continues to study clinical and social interventions aimed at harm reduction.

A decade ago I worked with scientists from Sweden’s Umeå University to publish the first scientific evidence that smokeless tobacco (“snus” in Swedish) played an impressive role in low smoking rates among Northern Swedish men from 1986 to 1999 (here and here). We published another study showing that in 2004 smoking among women also declined as a result of increased snus use (here).
I am the lead author on a new study documenting that snus continues to play a role in low Swedish smoking rates. That work, based on 2009 data, was just published in the Scandinavian Journal of Public Health (here), with coauthors Drs. Jan-Håkan Jansson and Mats Eliasson from Umeå University.
The chart on the left illustrates the most interesting finding from this study: Snus continues to play a role in low smoking rates among both men and women, but all tobacco use, including that of snus, is declining. Critics of tobacco harm reduction charge that snus and other safer smoke-free substitutes are a gateway TO smoking, and thus will lead to a negative population effect. The data from Sweden is conclusive. As we wrote, “…tobacco harm reduction is not contrary to overall reductions in tobacco use at the population level.”
We also documented the direct role snus plays in smoking cessation. From our study: “The prevalence of former smoking was 27% for men and 31% for women in 2009. Among men, only 27% of former smokers were never snus users, 39% were current snus users and 34% were former snus users. Among women former smokers, 70% never used snus, 19% were current users and the remainder were former snus users.”
Snus’s impact was seen in the smoking quit rate, which is the percentage of former smokers among ever smokers (current + former smokers). “The smoking quit rate among men was 71%; 52% were ever users of snus and 19% were never users. This was consistent with earlier surveys (reference here). The quit rate among women was 72%, which was considerably higher than previous years, reflecting increases in both ever users of snus (21%) and never users (51%).”
I have noted in this blog that American policymakers insist on population-level proof that vastly safer smoke-free products do not increase tobacco use (here and here). This study provides that proof: snus promotes low rates of smoking in Sweden and is also compatible with reductions in all tobacco use.
