Has anyone tried to vape on a higher nicotine content than 36mg, and if so, what kind of experience have you had as a result?
Yes. 2 or 3 weeks into vaping I was still smoking a pack-a-week (way down from 2 packs per day). I was chain vaping mostly 30 mg/ml with occasionally some at 36. I wasn't experiencing any withdrawal discomfort (I had decided beforehand to simply smoke when I wanted to smoke and vape when I wanted to vape), but neither was I feeling anything like nicotine od symptoms, so I decided to up the dose and see what happened with those last 2 or 3 cigs-per-day.
I tracked down some 48 and 60 mg/ml juice and started alternating a cart of 48 with a cart of 60. About 2 weeks of that and I was down to 1 cig every 2 or 3 days, and again, experiencing neither withdrawal nor nic od symptoms. The last time I thought I might actually enjoy a smoke was just after Thanksgiving dinner, about 2 months after my first vape, but I decided to pass on it (which surprised my wife, daughter and BIL), and I was done with smoking (which I didn't realize at the time).
Eventually (can't remember the exact timing, but not long) I realized I didn't need the 60 mg juice, and with the occasional nic-reduction experiment, I am now comfortable at the 32 mg/ml level. I will attempt to go lower in the future but, with the exception of a possible FDA ban, I'm not feeling any pressure to rush things.
I might have gotten to the same point without going to the hi-nic stuff, but OTOH if I hadn't tried it I might still be smoking 2 or 3 cigs a day. (And I must say - even If I had never gotten below a pack-per-week, vaping would still be a winning proposition for me.)
Good Luck & Keep On Vapin'
