Researchers at the Department of Veterans Affairs have begun to use genetic data from the VA's Million Veteran Program (MVP) to identify genetic variants that contribute to the risk of chronic use of alcohol, tobacco, and opioids.

The broad goal of this effort is to identify genetic variants contributing to sustained harmful substance use, which can provide opportunities for prevention and treatment.
