U.S. Surgeon General Warning on Marijuana Use in Adolescence and During Pregnancy

August 2019

The U.S. Surgeon General has issued a warning about the potential health risks of marijuana use in adolescence and during pregnancy. The warning, which states that no amount of marijuana use during pregnancy or adolescence is known to be safe, comes after recent increases in access to marijuana, and  long term trends in higher potency.  The Surgeon General notes a 2018 recommendation from the American Academy of Pediatrics against marijuana use during pregnancy based on concerns for its potential impact on the developing fetus. He also cites research suggesting that frequent marijuana use during adolescence is associated with changes in the areas of the brain involved in attention, memory, decision-making, and motivation, and notes that earlier initiation of marijuana use is associated with an increased risk of developing addiction.
