Searching around, it looks like even light smoking is still bad. Not as bad, but still bad.

"Light and intermittent smoking carry nearly the same risk for cardiovascular disease as daily smoking.... In addition, the risk of ischemic heart disease in light-smoking men and women aged 35 to 39 years who smoke 1 to 4 cigarettes per day is nearly 3 times that of a nonsmoker."

There's nothing wrong with taking a calculated risk, but it is a risk.

Just for reference. 1-4 per day would be about a pack every 8 days, averaged. I'd be curious how that compares to a non-daily smoker who as the grandparent suggests, only smokes about once every other day on average.

I expect it's still a significant health risk, but I've never seen studies on people who don't smoke daily.

Those rare smokers practically don't exist; either they are wise and just stop because they were just testing, or they increase their habit, because they are still testing, until they forget why they even started and need the narcotics to numb the pain they caused themselves.

How the damage happens is not important, but consider the possibility of slowly accumulating effects because of a slow rehabilitation potential.
