MENOMONEE FALLS, Wis. -- A Menomonee Falls woman and two friends are accused of giving her toddler a marijuana cigarette and videotaping the incident.

Police said the three adults were smoking pot, when they passed the marijuana to the woman's 2-year-old boy, WISN-TV in Milwaukee reported.

One of the friends recorded the scene on cell phone video, which came to the attention of police.

"It's impossible to tell whether the child puffs on it or blows on (the marijuana)," Waukesha County District Attorney Brad Schimel said. "If the child ingested any, it was a very small amount, because the test came up negative."

The child's 20-year-old mother was not charged with giving the child drugs since none was found in his system, but she faces misdemeanor child-neglect charges.

She still has custody of the boy, but she is being monitored by Waukesha County Human Services.

The two other people involved also face charges.
