The use of recreational marijuana is legal in the District of Columbia and 11 other states, and would be in Minnesota by now if Gov. Tim Walz had gotten his way.
But legal or not, young people and pregnant women shouldn't use the drug, according to the nation's top doc.
Surgeon General Jerome M. Adams issued an advisory to that effect last week.
"There is a false perception that marijuana is not as harmful as other drugs," Adams said in a news release from the U.S. Department of Health and Human Services. "I want to be very clear — no amount of marijuana use during pregnancy or adolescence is known to be safe."
The news release noted that THC in marijuana binds to receptors in the brain, producing euphoria but also potentially harmful effects, including intoxication and memory and motor impairments. Newer strains have been shown to be more potent, it said.
