If I want each puff to have the same amount of nicotine as each regular cigarette puff? I read somewhere that the 16mg liquid have as much nicotine as regular cigarettes but I think they mean they have the same amount of nicotine as 20 cigarettes but a lot less puffs. Well, I noticed I enjoy not just nicotine but also the act of puffing, and I really don't want to overdose myself. So what concentration should I get?
