“The only medically-approved uses for laudanum in the United States are for treating diarrhea and pain. Laudanum, as deodorized opium tincture, contains the equivalent of 10 milligrams of morphine per milliliter. By contrast, laudanum’s weaker cousin, paregoric, also known as camphorated tincture of opium, is 1/25th the strength of laudanum, containing only 0.4 milligrams of morphine per milliliter.” MORE ➲
