Effects of discontinuing daily morphine treatment on choice of the large reinforcer (top), trial omissions (middle), and body weight (bottom). Data are shown for the last session of daily morphine treatment (above “M”) and for up to the first 7 sessions after discontinuation. The shaded region indicates the mean (± 2 SD) for 3 baseline sessions. Body weight is expressed as a difference (kg) from body weight on the last session of treatment, calculated individually for each daily treatment dose of morphine.
