Update:
Just read (in a book, so no quotations) that by far the worst of the radioactive particles is polonium-210, which is present in large quantities in the phosphate-heavy fertilizers used for decades in tobacco fields. Apparently shifting to cleaner fertilizer and using strains of tobacco less prone to particle absorption like this would go a LONG way into making the tobacco less radioactive. This is something Eric should be asked about - if he knows where his tobacco comes from, and the practices on the specific farms.

Yes, I think this could make a big difference, so it may be worth finding out more about tobacco farming practices, just like it can be beneficial to get that information about the food you eat.
Cutting back on smoking frequency never hurts either, but what fun is that?
