42 years old. 6'1, 210. Started at 18 to kick cigarettes, which I did on and off from about 13 to 25ish. Used to do cigars, too. It didn't work because I only piped until about 20. Only started heavily smoking pipes again about 2.5 years ago when I got married and wife gave me the okay.
I smoke several bowls a day, could be 4-6, sometimes more, sometimes less. I NEVER inhale...if I accidentally inhale, I instantly have a choke/sneeze reaction. It's been so long since I was a cigarette smoker that my lungs don't remember inhaling, and don't want it. Also, I generally smoke mild blends. I can handle the stronger stuff, but generally just don't like it.
As for health problems, I did have some issues in the last year and a half, but that was A.) COVID, twice, and possibly even pneumonia the second time, and B.) I am allergic to cats, and live with two of them (I love them too much), and terrible pollen allergies. Some days I wheeze and have breathing issues, but there are several other environmental factors.
Some times I wonder if I'm smoking too much, but I know some folks do it way more with no ill effects. The relaxation it has for me outweighs the negatives, at least at this stage in my life. If I smoke indoors, it's with a wide up window and a fan, and we have an air purifier.
For those who only smoke one bowl a week or so, I don't think you have anything to worry about.
