Teen Mom 2 fans often refer to Leah Messer-Calvert as “Super Mom” because she seems so devoted to her family. But a bombshell claim in the new issue of In Touch reveals the devoted mother could have a serious drug problem.

In Touch exclusively spoke to a man who claims to be her drug dealer, who says Leah’s been “getting high for years.”

“I used to give Leah the pills myself; she’s picked up 30 to 40 pills at a time from me,” the alleged drug dealer tells In Touch exclusively. The drug dealer says the 22-year-old is taking the painkillers Vicodin, Lortab, Percocet and oxycodone. “She was withdrawing $1,000 a week to buy pills,” says the dealer.

The dealer also claims that as she became more famous, Leah began using someone close to her to pick up her drugs. (In Touch is withholding the name of the middleman.) “She gives [the middleman] the money and he gets them for her. They’re in this together.”

Though Leah’s mom, Dawn, denies her daughter uses drugs, a Messer family insider says, “I’ve seen Leah pop a handful of pills, chew them like they were candy and swallow them. She doesn’t even need anything to wash them down with,” noting that Leah’s excuse has always been back pain from a botched spinal tap during her labor with Adalynn, 20 months. “But it’s [actually] the pain from withdrawal that bothers her, not her back. She can’t go a day without opiates.”

After Leah’s husband, Jeremy Calvert, took to Twitter releasing an accusation of Leah cheating with her bad boy ex Robbie Kidd, In Touch contacted his friend. “If Leah is hanging out with Robbie again, she’s definitely partying,” Robbie’s friend Nathan Mullins exclusively tells In Touch of his pal, who was arrested in September for possession of a controlled substance without a prescription.
