A very small study suggests that tanning may be addictive. The study compared eight frequent tanners to eight infrequent tanners. Findings: 1) The frequent tanners preferred ultraviolet light more than the infrequent tanners did. 2) A drug that interferes with opiate addiction "reduced ultraviolet preference in frequent tanners." 3) The drug caused half of the frequent tanners, but none of the infrequent tanners, to "experience nausea or jitteriness, consistent with opiate withdrawal." This backs up previous findings that some tanners are obsessive. Researchers' theory: Ultraviolet radiation generates endorphins, which become addictive.
