Description
This is a UK study of 20 experienced e-cigarette users (12 males; 8 females) which aimed to compare the effects of i) high vs. low nicotine e-liquid concentration and ii) fixed vs. adjustable power settings on vaping behaviour, subjective effects, nicotine intake, and exposure to acrolein and formaldehyde in an everyday setting. All participants completed a baseline session and then four different conditions (each one weeks’ duration) under a) high nicotine, fixed power; b) high nicotine, adjustable power; c) low nicotine, fixed power; and d) low nicotine, adjustable power. Order was counterbalanced but the two fixed conditions always came first. The data include, under each condition: puffing patterns (puff number, puff duration, inter-puff-interval, volume of e-liquid consumed), craving and withdrawal symptoms, subjective (positive and negative) effects, and HPMA (for acrolein) and formate (for formaldehyde) exposure.
