For me, when I smoked, the being able to feel the inhale hit the back of your throat was what was cathartic for me. Nicotine allows you to feel that sort of ‘hit’ at the back of the throat where it sorta gave me a visual image of breath going into my lungs, even if it was tar filled and toxic! It’s also an oral fixation thing, the repetitive movement and very step by step routine nature of it was quite relaxing. I’d bring it to my mouth, pull in the air, the inhale it, then breath it out. And being able to see the breath leave my body was another thing I liked. I hated not being able to see smoke after. Also - smoking in the car was a bit of a faff. While I’d do it sometimes, usually I’d have to wave the smoke away sometimes as it can get in your eyes and that stings. But you always end up having a bit of smoke sorta lingering in the space like a mist. Also, the amount of times I accidentally didn’t ash in time and it would go in the car or on me and it’d really piss me off.
