As a nicotine addict I caution you against assuming addiction is not looming. In my experience the onset of nicotine addiction is sudden and consuming.
For some time, perhaps, you smoke or vape merely socially, experimentally, after a whisky at a party. Then, suddenly, perhaps after one too many the night before, ferocious withdrawal threatens. It is not a slow process, but a sudden toggle.
I will also add that in my experience a nicotine high only exists when consuming a large amount before you have developed a tolerance. I believe most addicts do not get real pleasure, either.
