Unflavored, strawberry, and tobacco e-liquids were all 50/50 vegetable glycerin/propylene glycol (VG/PG) and 18mg/mL nicotine; one KangerTech mini Protank 3 clearomizer was used per flavor and 12 different replacement atomizers were used for each clearomizer. Each e-cigarette was vaped using a standardized puffing protocol: 15 puffs, 1 puff every 30s, 4-s puff duration.
