I very much have that predisposition. I’ve noticed that I have addictive behavior towards sugar and caffeine as well (I’m fine as long as I don’t have any, but if I have some I’ll continue to crave more at shorter and shorter intervals until I go to sleep and it resets), and recently celebrated my third month nicotine free after about four years total smoking and then vaping.

Addictive proclivities are a personal defect normally. But when you exist in a context where there are people whose job it is to get you hooked on things, they become a handicap.
