A Florida couple has lost custody of their cancer-stricken 3-year-old son because they opted to treat him with marijuana-infused oil instead of chemotherapy, according to a report.

Noah McAdams’ parents skipped his chemo appointment last Monday after deciding to use natural remedies for his acute lymphoblastic leukemia, according to the Hillsborough County Sheriff’s Office.

The parents, Joshua McAdams and Taylor Bland-Ball, claimed their son hadn’t responded well to chemotherapy after being diagnosed with cancer last month.

“He had vicious mood swings making him violent, making him very emotional,” his mother told news station KTRK. “He also started to lose his hair right away after the first treatment.”

So the parents pulled the plug on the chemo sessions — prompting authorities to issue an endangered child alert when the family didn’t show up for last week’s appointment.

The family was quickly tracked down in Kentucky, and the boy was returned to a Tampa-area hospital, officials said.

A Hillsborough County judge ruled Thursday that Noah will go home with his maternal grandparents as his parents wage a legal battle to seek alternative treatments.

The parents testified that they began giving their son CBD oils, fresh foods and clean alkaline water in a bid to help him, according to the Tampa Bay Times.

“This is not about whether we’re choosing alternative therapies, natural therapies,” Bland-Ball told KTRK. “This is about our rights as parents to seek other options.”

Authorities said an investigation was also launched to determine whether the couple will face child neglect charges.
