Regarding other things "never smokers" may not understand: Before I started smoking (relatively late in life), I didn't really grasp that smoking is non-trivially immediately psychoactive. Like I thought it was something that you did just to do, and then it quietly wormed some sort of hook into your brain that made you feel bad if you stopped, but the whole thing happened entirely "subconsciously". Maybe I was just especially retarded, and most people properly understand this.
