“…A third example of physiological adaptation to chronic alcohol intake is found in the functioning of the hypothalamic-pituitary-adrenal axis. Ingested ethanol stimulates the axis, resulting in elevated levels of corticosteroids (particularly cortisol) and biogenic amines (especially epinephrine) in the blood and urine (Mendelson, Ogata, & Mello, 1971;Noble, 1973;Ogata, Mendelson, Mello, & Majchrowicz, 1971;Stokes, 1971). There is some evidence from research with animals and humans that with prolonged alcohol intake, a degree of adaptation occurs in this system (Kalant, 1962;Noble, 1973), although the extent of adaptation in humans is still unclear (Stokes, 1971).…”
