How does smoking affect the adrenals? I know it stresses them out but how? I don't drink caffeine but I do smoke. Is it possible to replenish and restore my fatigued adrenals with herbs if I'm still smoking. The same thing with my Thyroid. I'm using Black-Walnut Hulls powder. I know that smoking displaces the Iodine in my body but is it still possible using herbs to fix my (hypothyroidism) while continue to smoke?
