Drug overdose and the full moon.

Abstract

This study assessed the relationship between the phase of the full moon and the incidence of overdose as reported in five metropolitan Phoenix hospitals and the Maricopa County Medical Examiner over the 15-mo. period from January 1, 1976, through and including March 31, 1977. A chi-squared analysis was performed and no significant difference between the distribution of cases occurring during the full moon phase and that outside of these periods was found.
