I smoked for 24 years, on and off (mostly on!). From age 13 to 37. I quit in 2012, it was no big decision I run out of tobacco (always smoked rollies) and couldn't be arsed going to the shops and just decided to stop that crap there and then. I binned the rest of my smoking stuff (filters, papers,...) and never looked back.
Not long after I joined a gym and also that summer I stayed mostly outdoors, drinking by the river and never in bars. Never once felt the urge to smoke, quite the opposite. Pretty soon I developed an aversion to smoke bordering on a phobia.
I gag at the smallest whiff of cigarette smoke and the stale stench of it on a smoker makes me sick to my stomach.
In Germany smoking is still allowed in some bars, it's fucking ridiculous, but the cigarette industry is really powerful here (advertising cigarettes is still allowed and widespread!), so there's little chance this will change anytime soon.
Unfortunately for me, Metal bars tend to be smoking. I fucking hate it. A couple of hours in one of them is the most I can take and then I feel like shit the rest of the weekend.
There's an Alternative monthly gay night here but it's also smoking, so only been once and had to leave early and still felt rotten the next day.
