Jenelle Evans Back on Drugs? New Claims as Husband Blames Ex for Heroin Addiction

Is "Teen Mom" Jenelle Evans using drugs again? Rumors are surfacing after the 21-year-old "disappeared" for four hours, prompting her husband to tweet about the situation. Earlier he tweeted about his belief that Evans' ex-boyfriend was the one to allegedly get her hooked on heroin.

"Leaves at 3 am returns at 730am where… did she go for four hours late night???! Yea I am done," Evans' new husband, Courtland Rogers tweeted earlier today.

Friends began to worry about Evans, who has struggled with addiction to marijuana and drinking. Recently, rumors have abounded that the "Teen Mom" star is using some type of narcotic again.

"Jenelle struggles with drugs, which everyone knows, and when she disappears in the middle of the night we get terrified that she's using again. She doesn't always do the right thing and with Courtland freaking out, we started to get really worried that she's back on drugs," a friend told Radar Online.

Yet Evans took to her own Twitter account to allay everyone's fears. "I did NOT write any tweets on my twitter I haven't been on twitter since 6am. I went to chill with @Vkillemm at 3am… That's all," she said.

One friend has tweeted that Evans was with another of their friends on a website called Stickam, which is a live-streaming video feed. However, it is hard to track down the video from that specific time frame. Friends are skeptical, though, about what exactly Evans was doing for those four hours.

Earlier today, Rogers also tweeted that he blamed Evans' ex-boyfriend Kieffer Delp for getting his wife hooked on heroin.

"Just leave me and my WIFE … Mrs. Rogers alone. It's funny people think I am a junkie wait till they see this next season on how u did Jenelle and got her hooked on heroin … she almost died cuz of u," Rogers posted on Delp's Twitter page.

"U got Jenelle strung out and then bailed on her when she needed u most! And everyone thinks u are the good guy! This is sad," Rogers added.

He also promised that everyone would see the truth on the next season of "Teen Mom 2."

Evans has been in and out of rehab and probation for her drug habit, which has also threatened her relationship with her son, Jace. He is currently in the custody of Evans' mother, though Evans has repeatedly said that she would do "anything" to get him back in her care.
