I have gone to completely vaping from smoking and sent my first vape pen (Kanger ??) to my sister to help her quit smoking. The vape pen just didn't cut it for me & I went to a Vaporesso Revenger & an Eleaf Pico 75w. I like the Pico but just can't seem to get a big enough hit off it but do manage part of the day with it...now the Revenger I love...perhaps too much My sister is trying with the vape pen but I think she may have the same issues I had. She smoked more than I did (pack a day) and was a menthol smoker. I sent a small bottle of 6 mg nic to her to go with the pen. I have suggested maybe at least a Pico 75w and maybe a stronger nicotine but she is fighting it. I am thinking a juice with at least some menthol if not a tobacco with menthol would help her? Any suggestions appreciated. She wants to quit be seems to be having a harder time than I did.
