In the past year, Ryan Edwards and his ongoing journey with substance abuse became one of the central storylines on Teen Mom OG. And while he was candid with many parts of his struggle — including his decision to check in to rehab — many fans wondered what drug he was using during his battle with addiction. And now we finally have an answer.

On last night’s episode of TMOG, it was revealed that the father-of-one was using heroin. The confession came as Ryan and his baby mama, Maci Bookout, began to sort out a custody arrangement for their eight-year-old son Bentley. While making arrangements with his lawyer, the lawyer asked what his drug of choice was, and Ryan plain and simply said “heroin.”

The confirmation came after months of speculation that the 29-year-old was using the drug, which is tragically abused regularly to the point of it being labeled an “epidemic” within the United States, with opioid addiction being the leading cause of accidental deaths (in 2015, there were 20,101 deaths related to prescription pain killers and another 12,990 deaths involving heroin). Fans first feared the worst after they spotted what they believed to be “track marks” — aka the scars left by IV drug use — on his arms during one episode of the MTV reality series.

Fears for Ryan’s wellbeing ony increased when the show returned for its newest season, and his new wife Mackenzie confessed that he was (at his worst), spending up to $10,000 a day on drugs. Ryan has been on the straight and narrow since completing a stint in rehab over the summer, a decision that was made after MTV’s cameras captured (and aired) footage of Ryan drivign under the influence.

“A little over 30 days ago, I made the decision to check myself into a rehabilitation facility. I am back home now doing well, and life could not be better,” he said a statement over the summer. “Without the support of my wife and parents, I would not have been able to do this. Thank you all for your well wishes.”
