12mg nicotine e-liquids deliver a more noticeable throat hit and are typically used in mouth-to-lung (MTL) vaping. This strength is most commonly found in higher PG or balanced 50/50 blends, where lower vapour output helps keep the nicotine delivery comfortable and controlled.
12mg e-liquids are generally chosen by experienced MTL vapers or heavier smokers who want stronger nicotine satisfaction. They are not suitable for sub-ohm vaping, as higher vapour production can make this strength feel too harsh.
