I've been curious about this as well. For me I smoke maybe 2/month...one cigar a week at the very most. My guess is it's negligible compared to all the other toxic clouds we walk through in a given week. But hard data would be useful to see.
Edit: Table 1 might have our answers https://cancercontrol.cancer.gov/sites/default/files/2020-08...
I would guess it’s roughly linear. Should be good enough as an approximation. So if smoking daily is, say, -8 years life expectancy then smoking weekly is probably around -1 year. Once it’s very infrequent like once a month it’s probably negligible.
This is exactly what I was looking for. It seems like toning down to 1-2 cigars has measurable benefits but is about what I expected, especially with lung cancer.
