I want to get my dad a joytech ego AIO for fathers day so he can quit smoking because I have been cigarette free for two months since vaping. When I first started i got my Nic level to high and had an unpleasant experience I don't want to turn him off such a great thing like vaping by getting to high of a Nic and making him feel sick. My dad smokes Marlboro reds and he smokes around 4- 6 cigarettes a day what level of Nic should I buy him? Also he didn't like flavors he wants a juice to taste as close to his cigarettes as possible any suggestions?
