Reproduced from Shi, et. al, 2021, "The associations between prenatal cannabis use disorder and neonatal outcomes"; Chart: Axios Visuals

Marijuana products often don't provide adequate warnings about potential risks to pregnant women, according to a new study from the National Institute on Drug Abuse.

The big picture: Preterm birth, low birth weight and mortality are all more likely in babies born to mothers who have been diagnosed with cannabis use disorders.

By the numbers: Roughly 7 out of every 1,000 babies born in California in 2012, the most recent year of data in the study, was born to a mother diagnosed with prenatal cannabis use disorder.

  • Infants born to women with a cannabis use disorder were 35% more likely to die within a year of birth.

How it works: CUD is different from casual use. The diagnosis requires continued use "despite impairments in physical, psychological and social functioning."

Where it stands: Recreational marijuana is legal in 17 states, and medical marijuana is legal in over 30, often as a treatment for nausea, vomiting and pain β€” which pregnancy can cause.

  • However, researchers are concerned that the adverse health effects for babies may outweigh the therapeutic effects for mothers.
  • Only California, Michigan and Colorado require warning labels that mention risks for pregnant women on cannabis products, according to the study.

Senate Democrats demand answers on FBI's Kavanaugh probe

Senate Democrats are demanding that the FBI hand over "all records and communications" related to the FBI tip line set up to investigate Supreme Court Justice Brett Kavanaugh when he was a nominee in 2018.

Why it matters: The ask comes after the FBI revealed it received more than 4,500 tips about Kavanaugh when he was awaiting Senate confirmation amid sexual assault allegations. Only the most "relevant" of these tips were forwarded to the Trump White House.
