ב''ה, at this point I don't know if this website is all AI, but having been around basically the most toxic social media version of all this that may or may not have had any basis in reality and was that five minutes of everyone tweaking themselves into transhumanismmaxxing a decade ago .. but with that 'and if you're not doing this, that, cutting, self harm, scarification, hormones, Tik Tok tics and every other fad you're not worth caring about' ..
Life is, after all, a mostly nihilistic void and while people have gotten forever weirder the social 'game' is usually looking for ideas of something to do to fill it. Blah blah I don't really want to go into the tendency so many have to become competitive about everything, either, because there's so many bases for that and plenty of people are miserable and just can't have anything they're 'not good at' or they feel worse and so on.
That's a long blast to get to, y'know, if you do give a shit about them you can let them know you give a shit whether they're 'doing that,' whatever 'that' is, or not.
As to cigarettes, I don't know, I've sometimes been a comedic advocate like part of the comedy world and .. when the whole world smoked it probably was actually a better place except for the stink and cancers, so that's a tough one, just don't beat yourself up because without that they might as much be getting into every other dumb and dangerous thing people do to 'feel something' (bar fights, hazardous driving, clown college, meth, whatever) so it's impossible to know if they'll have some moment where smoking keeps them out of other pain. Though if they like the nicotine alone I gotta say the lowest strength pouches sure turn out to be the trick to getting through a modern workday without being the stinky or fiending type and the fancier NRT products are mostly bullshit.
