I smoke but have a weird relation with it personally. Just like eating it doesn't alter your state of mind on a deep level or make you unequivocally feel like shit physically but it still feels more unnatural than eating and i perceive it to be more harmful.
So when i just chill at home i almost never smoke. It seems like when my system is calm and i'm in a relaxed state cigarettes become overwhelming and produce feelings of disgust and anxiety in me
but as soon as i do my job that can be pretty heavy on the system (social stress, physical fatigue, meteorological conditions) i can smoke, i even WANT to. Few days ago just after returning home after a long day i chainsmoked like 4 cigarettes. I also smoke during my shifts. Though it's easier for people like me to completely stop and i should do it ASAP.
And something i also noticed is that smoking makes me more anxious. It's kinda treacherous as it's not evident to see but smoking during my shifts makes me more tired, jittery and shit.
