When it comes to the prestigious title of "worst baby daddy in the Teen Mom franchise," Adam Lind is pretty much the undisputed champion.
Of course, that's not to say he hasn't had plenty of competition over the years.
Take Ryan Edwards, for example.
Adam might have a lock on the worst baby daddy title, but it was Ryan who engaged in the most shocking behavior ever captured by a Teen Mom camera crew.
On last season's Teen Mom: OG finale, Edwards drove to his own wedding while so high on prescription painkillers that he nodded off behind the wheel.
It's important to note that millions of Americans struggle with addiction, and they deserve our sympathy, not our condemnation.
But that doesn't mean addicts aren't responsible for the things they do while under the influence, and Ryan very easily could've killed someone.
Ryan's wife, Mackenzie Standifer, took a lot of flak for "allowing" him to drive, but if you've ever tried to reason with someone who's on drugs, you know it's no easy feat.
And sadly, it's a situation Chelsea Houska has found herself in many times.
On last week's episode of Teen Mom 2, Chelsea watched the TM:OG finale with her husband, Cole DeBoer, and confirmed what many fans already suspected:
It turns out Chelsea can really relate to Maci Bookout's struggle.
“Her story is almost similar to what’s going on in my life,” Houska remarked to DeBoer while watching the episode.
She went on to liken Ryan's irresponsibly behavior to Adam's, saying:
“Imagine the kids were in the car? I have it set [Lind] can’t drive with Aubree. If that was him and the kids were in the car… That just makes me sick.”
The episode saw Chelsea complaining about Adam's shoddy parenting, which she attributes to his continued drug use:
"It’s just annoying,” she said.
“He thinks just because he goes over there that’s an effort. You go out there and you sleep, probably because you’re coming off drugs.”
Back in April, Lind tested positive for meth just hours before he was scheduled to visit with his daughter, and it seems Chelsea is intent on tightening controls over his visitation rights.
“I’m going to meet with the lawyer to get in writing that visitation has to take place in [his parents’] house," she said.
We're guessing she would encourage Maci to do the same.
