I've been a social smoker to say, possibly 1 pack a week if that. Anyhow I purchased the KangerTech subtank mini on a vaporshark evolve 30 box mod and been completely satisfied. Haven't touched real tobacco in months. It's a sub ohm .5 sub ohm coil on organic cotton 6% nicotine, hopefully the sub ohm vape is safe. Am I alone?
