Researchers used information from the nationally consultant Inhabitants Evaluation of Tobacco and Well being (PATH) longitudinal examine, undertaken by the Nationwide Institute on Drug Abuse (NIDA) and the FDA Heart for Tobacco Merchandise below contract with Westat.

Of those latest people who smoke who switched to a different product, 22.8% used e-cigarettes, with 17.6% of switchers utilizing e-cigarettes day by day.

Current former people who smoke who switched to e-cigarettes have been extra more likely to be non-Hispanic white, have greater incomes, have greater tobacco dependence scores and think about e-cigarettes as much less dangerous than conventional cigarettes.

An extra follow-up survey is required to determine whether or not that is proof of a sample of continual quitting and relapsing to cigarette smoking, or whether or not it’s a part of progress towards profitable quitting, stated the researchers.

“That is the primary examine to take a deep take a look at whether or not switching to a much less dangerous nicotine supply might be maintained over time with out relapsing to cigarette smoking,” stated Pierce. “If switching to e-cigarettes was a viable option to stop cigarette smoking, then those that switched to e-cigarettes ought to have a lot decrease relapse charges to cigarette smoking.
