CHICAGO — Warning: Marijuana use during pregnancy and breast-feeding poses potential harms.

That message would be written on medical and recreational marijuana products and posted wherever they’re sold if the nation’s most influential doctors group has its way.

The American Medical Association agreed Monday to push for regulations requiring such warnings be written on medical and recreational pot products and posted wherever they’re sold.

The decision was made based on studies suggesting marijuana use may be linked with low birth weight, premature birth and behavior problems in young children.

Critics say evidence of harm is weak, but while advocates agree that more research is needed, they say erring on the side of caution makes sense.

Some studies have linked marijuana use in pregnancy with childhood attention problems and lower scores on problem-solving measures.

There’s much more scientific evidence of harm from alcohol and tobacco than from marijuana, but marijuana has not been proven safe to use during pregnancy or breast-feeding.

The AMA voted to adopt the proposal, meaning it’s now on AMA’s lobbying agenda.
