Introduction. Around 50 percent of the tobacco in Norway is consumed in the form of snus, a smokeless oral tobacco. We examined Norwegian smokers' openness, and thereby the potential reach, to use e-cigarettes, nicotine replacement therapy products (NRT) and snus in the event of quitting smoking, in a society where snus use is common.

Methods. Using data from an online survey of 4,073 smokers from 2019 to 2021, we calculated predicted probabilities of smokers' being open, undecided and not open to use e-cigarettes, snus and NRT in the event they should quit smoking.

Results. Among daily smokers, the probability of being open to use e-cigarettes in the event of quitting smoking was .32. The corresponding probabilities for using snus and NRT were .22 and .19. Snus was the product with the highest probability of not being open (.60). NRT had the highest probability of being undecided (.39). Among smokers who had never used e-cigarettes or snus, the probabilities of being open were .13 for e-cigarettes, .02 for snus and .11 for NRT.

Conclusions. In a snus-friendly norm climate where smokers have traditionally used snus as an alternative to cigarettes, the probability of using e-cigarettes in the event of smoking cessation was higher compared to both snus and NRT. However, among smokers who had never used e-cigarettes or snus, the likelihood of being open to use NRT was similar to e-cigarettes, and higher than snus, which suggest that NRT may still play a role for smoking cessation.

Implications. In a snus-prevalent country in the endgame phase of the cigarette epidemic, where robust infrastructure for tobacco control in combination with the availability of snus has reduced smoking to a minimum, the remaining smokers seem to prefer e-cigarettes to snus if they should quit smoking. This indicates that availability of several nicotine alternatives might increase the likelihood of a future product replacement within the small group of remaining smokers.
