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 — 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.

The hard math behind America's labor shortage

Data: Bureau of Labor Statistics, Congressional Budget Office; Chart: Axios Visuals

Yes, the pandemic has created unusual temporary labor market dynamics. But in the bigger picture, the 2010s were a golden age for companies seeking cheap labor. The 2020s are not.

The big picture: In the 2010s, the massive millennial generation was entering the workforce, the massive baby bo0m generation was still hard at work, and there was a multi-year hangover from the deep recession caused by the global financial crisis.

Advocates fret Roe v. Wade's 49th anniversary could be its last

As Saturday marks the 49th anniversary of Roe v. Wade, the Supreme Court's landmark decision that legalized abortion access in the U.S., advocates warn the ruling is "more at risk now than ever."

The big picture: The Supreme Court in December heard a challenge to a Mississippi 15-week abortion ban that could throw Roe's survival into question, or at least narrow its scope.
