The Impact of Three Alternate Nicotine-Delivery Products on Combusted Cigarette Use: A Randomized Controlled Trial.

What Was Tested

This randomized controlled trial looks at Therapeutic nicotine (patch, non-peptide).

Smoking cessation is a critical public health goal.

Participants were randomized to 4 weeks of: (1) VLNCs; (2) e-cigarettes; or (3) no product.

During two switch weeks, one with an active nicotine patch and one with a placebo patch (in a double-blind and counterbalanced fashion), participants were told to not smoke their usual cigarettes.

Why It Was Studied

This study examined the ability of e-cigarettes and very low nicotine cigarettes (VLNCs) to serve as cigarette substitutes and whether a substitution was supported by steady-state nicotine from a nicotine patch.

Who Took Part

The age groups tagged for this paper are adults and middle-aged adults, both men and women.

How the Study Was Run

The researchers set it up as a randomized, double-blind and placebo-controlled study.

The participants were allocated by chance, so the Therapeutic nicotine (patch, non-peptide) group and the comparison group should start out alike.

Blinding on both sides kept the participants and researchers unaware of who received Therapeutic nicotine (patch, non-peptide).

A placebo (an inactive look-alike) gave the Therapeutic nicotine (patch, non-peptide) group a baseline to be compared against.

What Was Measured
