Tennessee Expands Law to Require Psychiatric-Drug Toxicology in Mass Shooting Cases
In July 2025, Tennessee lawmakers enacted a bill that requires medical examiners to test for psychotropic medications in the bodies of individuals who kill four or more people in a single incident. The legislation was expanded in 2026 to include cases where a mass shooting results in injuries but not necessarily four deaths.
The expanded law, sponsored by State Senator Rusty Crowe, directs the University of Tennessee Health Science Center (UTHSC) to collect the toxicology results, analyze them, and submit a quarterly report to the Tennessee General Assembly. The reports will be made publicly available, allowing lawmakers and the public to review the data.
The Tennessee measure follows a national conversation about the safety of prescription psychiatric drugs. The drug labels for many antidepressants and other psychotropic medications list a range of adverse events that can include aggressive or violent behavior. The law does not assert causation; it simply requires that data be gathered and reported.
Under the 2025 version of the bill, medical examiners were instructed to focus on psychotropic drugs in autopsies of mass shooters who killed four or more people. The 2026 amendment broadened the scope to cover shootings that leave victims wounded, reflecting the fact that many high‑profile incidents involve injuries rather than fatalities.
The University of Tennessee Health Science Center will compile the toxicology findings and produce a quarterly summary for the state legislature. The summaries will be released to the public, creating a new source of data that has not previously been available at the state level.
The legislation was championed by the nonprofit AbleChild, which has advocated for greater transparency around psychiatric medication use in violent incidents. AbleChild’s founder has worked with the Tennessee General Assembly to draft the bill and has highlighted the need for data to inform policy.
The law also aligns with actions taken by other states. For example, several states have required toxicology testing for psychotropic drugs in the bodies of individuals who commit violent acts, but none have mandated that the results be reported to the public.
The Tennessee bill was signed into law by Governor Bill Lee on April 30, 2025. The law took effect on July 1, 2025. The 2026 amendment was passed by the General Assembly and signed by the governor on June 7, 2026.
The legislation is part of a broader debate about mental health and public safety. The U.S. Department of Health and Human Services, headed by Secretary Robert F. Kennedy Jr., has highlighted concerns about prescription psychiatric drugs, but has not yet issued guidance on toxicology testing in mass shooting cases.
The Tennessee law is the first state to require systematic toxicology testing for psychotropic drugs in mass shooting cases and to make the results publicly available. The data collected by UTHSC will be the first national source of information on the prevalence of psychiatric medication use among mass shooters.
The law does not require that individuals on psychiatric medication be treated differently by law enforcement or the courts. It simply requires that the presence of psychotropic drugs be documented and reported.
The next steps for the Tennessee law involve the UTHSC’s quarterly reporting and the state legislature’s review of the data. The law’s impact on policy and public perception will become clearer as the data are released.
The legislation is a significant development in the ongoing discussion about the safety of prescription psychiatric drugs and their potential link to violent behavior. By mandating data collection and public reporting, Tennessee has set a precedent that other states may follow.
The law remains in effect, and the UTHSC will continue to compile toxicology results. The Tennessee General Assembly will review the quarterly reports and may consider additional measures based on the findings.
The Tennessee law is a landmark step toward greater transparency about the use of psychiatric medication in violent incidents. It provides a new data source that may inform future policy decisions and public discussions about mental health and public safety.
