>>2159185like I said: 10ml liquids contain 3-18mg nicotine. for me 10ml lasts a week and I'm at 6mg, hence 6mg nicotine a week compared to 20-40 cigs a week with 1-3mg nicotine, hence 20-120mg nicotine.
For people that want a cigarette experience and a small good device I recommend cigma vape, pic related.
