Lawmakers in Wyoming have voted to include methamphetamine use during pregnancy in the state's definition of child abuse but have decided not to carve the offense out as a separate felony, the Associated Press reported Feb. 9.

The state House of Representatives voted 39-21 to approve the amendment to the state Child Protective Services Act. Under the revision, women who expose their unborn children to methamphetamine could be referred to drug court and then treatment; those who fail to abide by the court's order would face up to 90 days in jail.

An earlier version of the bill would have made prenatal exposure of a child to meth a felony punishable by prison sentences.

Meth-using mothers could still lose custody of their children under the bill approved in the House.
