That seems high.

Smoking shortens life by about ten years-- but not so much if you stop by age 40. This may imply that if we get decent anti-aging tech, smoking won't be a serious risk. How hard would the tech be to not be bothered by cigarette smoke?

Let's assume someone who didn't stop smoked for 40 years-- two packs a day. That's 40 x 365 x 40 = 584,000 cigarettes. Divide that into 10 years worth of minutes, and it comes out as .9 minutes, assuming I set up the calculations properly.

I think there's an error in your calculations.

If someone smoked for 40 years and that reduced their life by 10 years, that 4:1 ratio translates to every 24 hours of being a smoker reducing lifespan by 6 hours (360 minutes). Assuming 40 cigarettes a day, that's 360/40 or 9 minutes per cigarette, pretty close to the 11 given earlier.
