Long-term impact of the U.S. Armed forces Zero-Tolerance drug policy on female veterans

In 1980, the U.S. military instituted a zero-tolerance policy for illicit substance use that led to a reduction in such use during military services. Long-term post-military effects have not been studied.

National survey data from 2012-2013 were used to compared veteran versus non-veteran differences in sociodemographic, behavioral and substance use and psychiatric diagnoses among women by cohort (i.e., those younger than 52 who would have entered the military under the no tolerance policy, and those older than 52 who would have entered before this policy was implemented). Multivariate interaction analyses between cohorts and veteran status were used to identify significant changes in veteran-non-veteran differences between these age cohorts on during the decades following the implementation of the zero-tolerance policy.

Significant interactions primarily involved substance use diagnoses which were less frequent among veterans than non-veterans in the younger group of women, in contrast to the older group in which veterans had greater rates of substance use than non-veterans. These patterns were less robust for alcohol than substance use disorders and were not significant for psychiatric disorders.

The zero-tolerance policy appears to have had a long-term effect resulting in less substance use disorder and, to some extent, less alcohol use disorder among veterans as compared to non-veterans who served in the military after the zero-tolerance policy was implemented.
