Preference for sweet foods and higher body mass index in patients being treated in long-term methadone maintenance.

Opiate use has been associated with preference for sweets in both humans and animals. In 2002, the food preferences and eating habits of non-institutionalized patients in methadone treatment and controls were measured and compared. Questionnaires were administered to 14 patients and 14 controls with similar demographic characteristics (there were 19 women and 9 men ranging in age from 19 to 59 years).
