Authorities said they plan to do drug testing sometime this week on two toddlers who appear on a videotape being taught to smoke marijuana by two teens.

Child Protective Services said the 2-year-old and 4-year-old appear to be healthy and show no lingering problems from the marijuana.

A hearing to determine whether they will be returned to their mother was set for later this month. Authorities said the children's mother was asleep in a back bedroom during the incident.

The boys were removed from their Watauga home last week after police in nearby Fort Worth found the videotape while searching the house during a burglary investigation.

The children's uncle, 17-year-old Demetris McCoy, and his friend, 18-year-old Vanswan Polty, have been charged with injury to a child. The felony carries a penalty of probation to 10 years in prison.
