Honestly, to me smoking cigarettes and using drugs are two very different things. Incomparable for a question like this. Smoking cigarettes is almost the opposite of drugs in terms of doing it in public, outside, designated areas, etc., to which using drugs, often times (in my life), can be found around parties, inside, less public etc. I'd never judge anyone for
doing either. Abusing is another thing. Cigarettes, I'm not a user. I don't consider myself a person who smokes, but if someone I'm close with had a hard day and just wants a cigarette and invites me to smoke one with them, maybe! It's a lot like drinking to me. Or closely related, smoking cigars. Very social. Something to do while you're chatting or decompressing.
Being a HEAVY smoker is different. Apparently, according to the centers for disease control and prevention, a person needs to smoke over 100 cigs in their lifetime (and actively smoking) to be considered a smoker. A heavy smoker is 25 or more cigarettes in a day. I don't know of any friends or close colleagues that would fall into either of these categories, but I think my grandparents were up there. I don't really like the smell or idea of what cigarettes put into your lungs, so I think I naturally don't associate with people who smoke heavily. So long answer for that one is no, smoking a cigarette doesn't affect the way I'd think about a person.
Drugs, as I'm sure everyone can probably agree with, is another one that isn't black or white. What do you consider a drug?? I'm constantly having Caffeine. Like, all day every day. Built up a pretty nasty tolerance. Alcohol, Weed, Nicotine are all also drugs that I'd say are super common in my life and the people I associate on the regular. Wouldn't judge people for that. Psychedelics like shrooms or LSD is pretty extreme to me, I've never really considered trying it. I know a large handful of people who pretty regularly would take things like that and they've always been awesome and nice people so I don't judge for that. Same thing for cocaine or other uppers/party drugs. Never done anything like that myself but I think that's just for lack of desire, I don't judge people for that!! I think if I were to maybe be a little judgemental, I think it's would be against people who abuse medicines or other downers like Lean or sleeping pills etc knowing how lethal it is, and not caring. That feels really wreckless to me, and I'd wanna evacuate from that situation
I'm typing a lot, hoping to get a lot of TBT for this response but all this to say that I don't think I judge people based on their drug use either! Theres literally no need to judge anyone, like who cares ? It's their life and their desire for those experiences, who am I to judge someone for wanting to try something with the little time we all have on earth.
