Talent? No. 35 years of smoking and likely 45 of nicotine use all told. Call myself a dependent yet guess one could rightly say addict. Nicotine soothes something in me. Not sure what but it does, physically & psychologically.
I vape an average of 5 ml per day, which works out to roughly 90 mg. We absorb roughly half that ergo I'm vaping around 45 mg per day. Currently, I also rub a bit of snuff now & then (not whilst vaping but instead of it yet adjunct). Not sure what nicotine the Choke-A-Holic snuff provides for absorption.
The "nominal", or amount one would get if not using it directly, yet what is present natural is about 11 mg daily. Tomatoes, eggplant, grasses all have nicotine to some degree. People usually take in that small bit.
