56 yr old Brad Pitt

That picture makes me want a cigarette. I should be ashamed to say this, but I had my first cigarette in 2016, at almost 35, then started smoking two years later, at 36.
Now two years since I've started, I guess you could call me a smoker - It's the 24th today, and I've smoked 11 cigarettes this month. So I'm ABSOLUTELY averaging less than one a month, and I'd have to look back at the records I keep, but I probably average in or around 1/2 to 3/4 a day, for the past six months or more. I smoked more at other times, but really didn't want to become a smoker, so massively dropped what was always a small habit.
I'm looking for any study to show that something like two cigarettes every Sunday evening is neutral to your health, or doesn't make a person look much older or something like that.
But thus far, all the information I have is that smoking to any degree is bad. Although the same goes for drinking, and pretty much anything bad for you.
My other concern is if you are a relative nonsmoker, I'm thinking it's possible that you are damaging your lungs by constantly exposing your somewhat "virginal lungs" to cigarettes. And that maybe smoking 1-2 cigarettes a day may be less damaging than 1-2 a week for that reason, that your lungs are somewhat adapted to the toxins if you are smoking daily.
Since I can't answer any of these questions, I'm just not smoking very often. I think I'll have to more this month, and stop at 13 for the 30 days of November. Although I'm a hypochondriac, so probably not the best judge of what is a good or bad amount of something to do.
COVID has made me think a lot of people are hypochondriacs...yet they are almost all overweight or alcoholic opioid attacks or whatever else. Just that picture of Brad Pitt speaks volumes - if he cares so much about his health/lungs enough to wear that stupid COVID mask, why TF is he smoking a cigarette? Lol. Although who knows - maybe he only smokes a few cigarettes a week like me, and he actually is healthy, and concerned about his lungs enough to rarely be smoking. If Brad Pitt is a regular cigarette smoking person, I am amazed at how he has managed to keep his looks - considering he is 57 soon, he looks great. He's probably had a lot of work done...but it's not showing yet.
