Positive THC Tests Place New Mothers on Child Abuse Registries in Multiple States
State-level divergence between marijuana legalization and child welfare reporting laws has created a legal gray zone that disproportionately affects postpartum women, according to a joint CBS News...
More than 1,000 new mothers in Idaho have been placed on child abuse registries following positive THC tests at the time of childbirth, according to a joint investigation by CBS News's '60 Minutes Sunday Morning' and The Marshall Project published in August 2026. The findings surface a conflict between state marijuana laws and mandatory child welfare reporting statutes that varies sharply across state lines.
In Idaho, marijuana remains fully illegal under state law. Hospital drug screening of postpartum patients that returns a positive THC result can trigger mandatory reports to child protective services under Idaho Code § 16-1619, which requires health care providers to report suspected child abuse or neglect. The CBS News and Marshall Project investigation found that in some cases a single positive test, with no other indicators of neglect or harm, resulted in a mother's name being entered into Idaho's child abuse and neglect registry.
In more than 40 states, marijuana is legal for medical or recreational adult use, according to the National Conference of State Legislatures' current tracker of state cannabis laws. Dr. Stephen Patrick, a neonatal intensive care physician and researcher who studies the opioid crisis's effect on pregnant women and infants, told CBS News that automatically referring mothers to child welfare authorities or law enforcement based solely on a single THC-positive drug test — including in jurisdictions where adult marijuana use is lawful — may not align with available clinical evidence on neonatal risk. Dr. Patrick's peer-reviewed research on neonatal abstinence syndrome has been published in journals including the New England Journal of Medicine and JAMA Pediatrics.
The federal dimension involves the Child Abuse Prevention and Treatment Act (CAPTA), 42 U.S.C. § 5106a, which conditions federal child welfare grants on states having policies that require health care providers to notify child protective services when infants are identified as affected by substance use. The statute does not specify which substances trigger notification, leaving states to set their own thresholds. What documents would clarify the full scope of the issue: state-by-state CAPTA compliance plans filed with the U.S. Department of Health and Human Services, hospital internal drug-testing protocols, and aggregate data from individual state child abuse registry systems — most of which are not publicly released in searchable form. The investigation did not specify how many states beyond Idaho have produced comparable registry placements solely from THC-positive tests, nor the total number of women jailed nationally in connection with such findings; those figures remain unknown pending further public records requests to state child welfare agencies.
