When Thomas Looby took his sick 6-month-old to a hospital in May, officials initially suspected the child's ailment was heat-related.

Looby and his family were at a festival in Duluth when they noticed the child was lethargic, according to Channel 2 Action News.

But when tests on the child came back positive for marijuana, arrest warrants were issued for Looby, alleging the medical THC oil he used likely seeped into the baby’s skin, Channel 2 reported.

“I guess you could say the baby was high,” Suwanee police Capt. Shane Edmisten told the news station.

Looby turned himself in to authorities Monday on charges of reckless conduct and possession of a schedule I controlled substance, Gwinnett County jail records indicate.

Looby showed police a California doctor’s letter for the medical marijuana, but authorities said the concentration prescribed is not legal in Georgia, Channel 2 reported. Looby, who is originally from California, used the oil on his hands for arthritis.

“I guess the contact just with the oil on his hands with the child seeped into its skin and made it high,” Edmisten told Channel 2.

Edmisten said this is the first time they’ve ran into a case such as this and admitted making the arrest was a difficult call.

“We can’t allow the children to be affected by this,” he said.

Police said the baby is doing fine.
