More drug issues for troubled Ryan Edwards of 'Teen Mom OG'

Edwards' jail stay was short and he was free Wednesday morning after posting bail. This news does not come as a huge shock to "Teen Mom" fans.

As previously reported on Monday night, Ryan and his wife Mackenzie revealed they were expecting. The pregnancy news comes less than a year after Edwards' drug problems were confirmed on the reality series.

Ryan Edwards terrified "Teen Mom OG" viewers as he was filmed driving himself and bride-to-be Mackenzie to their wedding ceremony. He was seen slurring his words and nodding off while Mackenzie grabbed the wheel and continuously nudged him awake before shutting off the in-car cameras. Ryan checked into rehab days later, but only stayed 20 days before leaving the facility, telling Mackenzie he was clean and had graduated the program early.

How will Mackenzie deal with Ryan's problems now that she is pregnant?

It was also revealed during that time that Ryan's drug of choice was heroin and that the reality television personality was spending $10,000 a week to maintain his addiction. Since his brief rehab stay fans have continued to question his sobriety, with the majority believing that he was still using.

Edwards' ex-and mom to son Bentley, Maci Bookout, also had a hard time believing Ryan was clean and put in place strict guidelines before allowing him to spend time with their 8-year-old son.

One of the guidelines included Edwards undergoing drug testing at Maci's expense, however, Ryan continuously refused to oblige, leading not only Maci, but viewers to believe he could possibly still be using.

Mackenzie claims that Ryan's arrest has nothing to do with his sobriety now, but stems from his previous issues. At this time not too many details have been released concerning Edwards' recent arrest.

As reported, Ryan and Mackenzie's pregnancy news just broke several hours ago. Fans were already skeptical, now this just adds fuel to the fire and most likely places a lot of doubt in Mackenzie's mind.

A few of the "Teen Mom" reality cast members have reacted to Edwards' arrest on the social media. Former cast member David Eason commented on Ryan's arrest via Twitter:

As previously reported, Jenelle Evans' husband David Eason was terminated from "Teen Mom 2" following a homophobic rant back in February.

At this time Jenelle is reportedly awaiting news as to whether or not MTV will fire her as well. New "Teen Mom OG" cast member Mackenzie McKee tweeted for followers to stop sending her DM messages about staying with her "drug baby daddy," stating that they had her confused with Mackenzie Standifer.

This could not come at a worse time for Mackenzie Standifer, she is pregnant, and has stood by Ryan through a lot in their short time together. Details on Ryan Edwards' arrest and future endeavors with "Teen Mom OG" will be updated as they are released. Stay tuned for all the latest "Teen Mom" news.
