You can calculate conditional probabilities based on chances of quitting and not quitting cigarettes in the future.
This would make micromorts very situation dependent which would diminish their value as a statistical tool. Ex smokers would get far more micromorts from a single cigarette than people who’re just trying smoking.
In the case of smoking, a certain number of pack years become a permanent but still a diminishable risk factor past certain age. Before that age, both COPD and cancer risk can revert back to normal levels if you quit smoking. This makes perfect sense in a model where the body is able to repair itself but the repair mechanisms can be overwhelmed with a sufficient stimulus.
Using a linear model pretty much ignores the body’s ability to heal itself and the ability to remove harmful substances.
We can measure in a lab how much of a substance you need to give rats to kill 50% of them. It’s plausible that a 1/1000 of that substance can still do harm to the rats but we have no clear way of finding out.
Many substances are useful with the right dosage, and lethal with an overdose.

Even an acitivity like driving a car is situation dependent. Careful drivers have a different risk than reckless ones. At the same time the table doesn’t show you separate values.

I agree with that model, but I would point out that there are plenty of people out there who consider the bodies ability to heal itself from cancer pretty nonexistent.
