my experience has been that once you get bronchitis, is awful horrendous sick, the first time...(acute)
it can become chronic bronchitis, easily, and the smoke may be contributing to its chronic state.
once it has become chronic, its no where near as bad as the first time. it could be attributed to many things.
my moms dad would smoke cigs, and a pipe; she has chronic bronchitis her whole life until she moved out...
i had pretty bad bronchitis once, and now have a raging autoimmune DO.
i smoke marijuana medicinally to help with this, and take an immune system suppressing drug. if i did acquirer bronchitis again, id be in some trouble...
so maybe the pot is to blame...?
you could find out how the infection/inflation is being triggered by going to the doctor; viral, bacterial, situational.
