It's no secret that Jenelle Evans loves smokin' a toke, but we saw her drug use take a turn for the terrifying during Teen Mom 2's emotional Season 4 finale. Jenelle reunited with her wayward ex-boyfriend, Kieffer Delp, and immediately got hooked on heroin!

"When I got his [Kieffer's] support, then he wanted me to do the drugs, and he's like, 'oop, let's do it,'" Jenelle told Dr. Drew during Teen Mom 2's Season 4 reunion special. "That's the first time in my life I've ever tried it. I didn't like it at all, I was throwing up every five minutes, and I had to go to the hospital three different times, get IVs hooked up into me, having panic attacks, anxiety attacks ... I never even knew what withdrawing was."

Jenelle told Dr. Drew that she never actually injected herself with the drug, saying "no, I don't know how to do that," and explained that she broke up with Kieffer after having an overdose.

"I woke up at 5 o'clock in the morning because I felt like I was about to die. I felt like my organs were shutting down. I called my mom and said 'please, I know you haven't been talking to me for three weeks, but come help me I need your help.'"

Sadly, Jenelle was arrested for heroin possession on April 23, though she claims the drugs weren't hers and that she's been sober since November 2012 (when the reunion special was filmed). She and Kieffer haven't been in touch since their breakup, and as far as we know he's sober and living in New Jersey with his mother.
