No effect on effect: Smoking would not be expected to change the effectiveness of doryx (doxycycline). If smoking and Doryx (doxycycline) both upset your stomach, one could make the other more distressing, but i doubt you'd be smoking if it routinely upset your stomach. You shouldn't smoke anyway! stop it now and save a lot of healthcare dollars and misery later.
