Acute analgesic effect of nicotine vaping using three experimental pain induction tasks: a randomized, placebo-controlled laboratory study.

What Was Tested

Researchers studied Therapeutic nicotine (patch, non-peptide) in this randomized controlled trial publication.

Assess the effect of acute vaped nicotine on subjective and behavioral indices of pain sensitivity using three tasks designed to probe distinct mechanisms of analgesia.

Why It Was Studied

Experimental evidence supports an acute analgesic effect of nicotine which may reinforce nicotine use among those with chronic pain.

Evidence for nicotine analgesia have primarily been gathered in combustible cigarette users and have not been extended to electronic nicotine delivery systems (ENDS or vaping).

Who Took Part

The age groups tagged for this paper are teenagers, young adults and adults, both men and women.

This study recruited ENDS users (N = 86) to undergo a paced vaping protocol followed by pain tasks in counterbalanced order.

Across four sessions, participants vaped e-liquid containing nicotine or placebo, and flavor or no-flavor in a 2 × 2 within-subject design.

How the Study Was Run

The design is described as randomized, double-blind and placebo-controlled.

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).

Some participants received a placebo instead of Therapeutic nicotine (patch, non-peptide), giving a reference point.

Assessments included cold pressor, submaximal effort tourniquet to induce ischemic pain, and temporal summation of heat pain, an index of central sensitization.

What Was Measured
