how? It literally doesn't impact you if they aren't being douchebags about it
look i have a friend who i used to chill with who would do nothing but go on about his loving vaping rig and blow smoke in the edgiest ways to try to illicit responses from everyone else. he works a vape shop now and all i see on his snapchat are videos of him at work asking people to stop by because it's slow or he has nobody to hang with.
I've smoked hookah, cigarettes, e-cigs, vapes, and all these made me feel loving pretentious as forget. Hookah is pretty much a social thing that I do with my girlfriend and her friends, e-cigs and vapes are just another thing tech nerds can compare, just like people do with their phones or any other piece of technology they have. cigs are loving trash and i only smoked those when i was pissed off at someone or had a bad day at work.
so they're being douchebags about it.
tbh I find a lot of recreational drug users cigarettegy
you can smoke and not be a cigarette, just like you can do ANYTHING ELSE and not be a cigarette. weed is cool but a lot of people make it uncool by being cigarettes about it.
