A Pennsylvania mother is accused of lacing her baby son’s formula with a drug that helps heroin addicts kick the habit so he would sleep.

Corinne Barndt, 28, told police she spiked her eight-month-old son’s formula six or seven times from November 2015 to April 2016.

The drug she is accused of using on her child is buprenorphine. It’s a synthetic opioid painkiller also used to wean addicts off heroin.

Dangerous drug: Barndt allegedly used buprenorphine, which is a synthetic opioid painkiller also used to wean addicts off heroin

Buprenorphine is addictive and can cause respiratory problems and even death when taken in high doses, or when combined with other substances.

The Haycock Township woman was arraigned Thursday on charges of child endangerment and reckless endangerment, reported the Allentown Morning Call. She remained jailed Friday in Bucks County Prison on $1million bond.

Ms Barndt faces a preliminary hearing on August 8.

According to online records, Ms Barndt got in trouble with the law in May when she was arrested for public drunkenness at the Quakertown Memorial Park.

Information found on her Facebook account suggests that she also has an older daughter.
