She was also ordered to attend parenting classes.
Authorities say Barraza was arrested last month after her sister noticed the 4-year-old had slurred speech and droopy eyelids. The sister took the girl to a hospital, where tests apparently revealed she had marijuana in her system.
Authorities say Barraza initially denied the girl had ingested marijuana, but later said the girl grabbed the pot-laced brownie before she could stop her.
