This study will provide an initial assessment of the acceptability of the Nicotine Lactate Delivery System (P3L) after ad libitum use and the ability of combustible cigarette (CC) smokers to use P3L to maintain their customary nicotine intake, in a manner comparable with their own brand of CC or the VUSE e-cigarette system.
The total duration of the study for an individual subject will be between 3 and 8 weeks, including 1 day for the screening visit, 3 days for the ad libitum use sessions (P3L, VUSE e-cigarette system and subjects' own commercially available non-menthol CC), 1 day for the preference evaluation session (subjects will be given the choice of using ad libitum the P3L or the VUSE), the 2 to 10 days of interval between each visit, and 7 days for the passive safety follow-up period.

The pharmacokinetics (PK) and pharmacodynamics (PD, i.e., subjective effects) profiles, will be evaluated as well as the safety and tolerability of the P3L.

Other P3L

Ad libitum use for a maximum of three hours. P3L delivers, on average, 80 µg of nicotine per puff under Health Canada Intense smoking regime.

Other VUSE

Ad libitum use for a maximum of three hours. VUSE delivers, on average, 80 µg of nicotine per puff based on the CORESTA e-cigarette recommended smoking regime.

Other CC

Ad libitum use of the subject's own brand of non-menthol CC for a maximum of three hours.

P3L Product use Experimental

Subject product use was randomly assigned for each ad libitum use session, following a sequence of product exposure comprised of the three products (P3L, VUSE, and CC).

VUSE Product Use Experimental

Subject product use was randomly assigned for each ad libitum use session, following a sequence of product exposure comprised of the three products (P3L, VUSE, and CC).

CC Product Use Experimental

Subject product use was randomly assigned for each ad libitum use session, following a sequence of product exposure comprised of the three products (P3L, VUSE, and CC).

Change From Baseline Plasma Concentration of Nicotine/Cotinine After Each ad Libitum Use Session.

For each ad libitum use session (P3L, VUSE, and CC), change from baseline plasma concentration of Nicotine/Cotinine was measured from two blood samples collected before product use (to provide baseline measures) and from two blood samples collected following product use (to show change from baseline).

Overall Score of the Short Version of the Questionnaire of Smoking Urges (QSU-brief). Total Score; Factor 1 (Reward); Factor 2 (Relief)

The QSU-Brief questionnaire is an instrument used to measure urge to smoke. Subjects were asked to respond to 10 questions, scored from 1 to 7 on a 7-point scale. A score of 1 on this scale indicates a very low urge to smoke, while a score of 7 indicates a very high urge to smoke. Subjects were asked to complete the questionnaire before, during, and after each ad libitum product use session. (P3L, VUSE, and Subjects' Own Brand of Non-menthol CC). Two factor scores and a total score were derived. Factor 1 represents the desire and intention to smoke with smoking perceived as rewarding, while Factor 2 represents an anticipation of relief from negative effect with an urgent desire to smoke. Products were compared over all timepoints using a repeated measure model using values after t0. The model adjusted for baseline value, sequence, and period with repeated measure over time and a random effect in subjects. Adjusted mean over all timepoints, for each timepoint, were estimated.
