Ryan Edwards could spend years in prison after yet another drug arrest earlier this week. As the former "Teen Mom OG" star remains in custody after being fired by MTV, a lawyer is speaking out about the time he is facing as a result of his charges and revealing why the reality star will likely not have the option of striking a plea deal for probation over time behind bars.

On July 24, Hollywood Life told readers that Edwards had been taken into custody [VIDEO] on July 23 for possession of heroin, which won't bode well for him because he's already on probation for the same charge stemming from a case last year. As the outlet explained, Edwards has proven himself as a repeat offender after spending a short time in rehab last spring.

Ryan Edwards violated his probation

“It really depends on the case, as far as whether somebody would be going to jail or to rehab after getting busted for heroin possession," criminal defense lawyer Ben Raybin explained to Hollywood Life. According to Raybin, who works out of Edwards' home state of Tennessee, treatment is typically a reasonable option for drug offenders [VIDEO] but after multiple charges are given, especially after probation, it's hard to say whether or not the judge will put their foot down. "Sometimes the judge says enough is enough and says they are going to jail and at that point they can put all the offender’s sentences into effect," the attorney, who is not currently working with Ryan Edwards, explained.

Raybin went on to tell Hollywood Life that Edwards, the former boyfriend of "Teen Mom OG" star Maci Bookout, is facing 11 months and 29 days in jail for his recent charge of heroin possession.

However, because of his prior charge and probation, the judge on his case could decide to add more time to his potential sentence. Breaking the additional time down, Raybin said that he has a pending six month sentence tacked on to his probation, which he violated, and a suspended term of 11 months and 29 days that stems from his 2017 arrest.

What's the largest amount of time he'll receive?

Although Ryan Edwards would have been able to evade the 11 months and 29 days if he had completed his probation without incident, he failed to do so and a judge now has the authorization to un-suspend his potential jail term. "Worst case scenario he could actually be looking at [two and a half] years in jail," the attorney explained. "I think it’s probably unlikely that [Ryan] would get totally maxed out on all of that but he is potentially facing [two and a half] years total in jail at this point."
