Phoenix fire officials say two 18-year-old women and a 19-year-old woman were in the area of Seventh Avenue and the Carefree Highway when they called for help Saturday night.
Crews responded around 7 p.m. and were told the teens were not hurt but had eaten mushrooms.
They found the trio about a mile from the highway.
All three were taken to a hospital for evaluation, but officials say they did not suffer any serious injuries.
