Been a month since you posted this but there's a spreadsheet in the main description of the mod that has a list of what traits are static/dynamic and how to obtain/lose them to some extent.

Smoker is a dynamic trait that can be lost by not smoking for 45 days.

Hey, I noticed something in the code that might need a small adjustment! Right now, it checks if currentTimeSinceLastSmoke == 10 to update the DTdaysSinceLastSmoke counter. However, it might be better to use >= 10 instead of == 10. The reason for this is that if the exact value of 10 is missed, like if it skips to 11 or higher, the code won't update properly. By using >= 10, it ensures that the counter still increments even if the exact value isn't hit.
