While "Teen Mom 2" star Leah Messer has successfully passed her drug test, viewers of the reality show are still doubtful. Some are convinced that the blonde beauty is abusing prescription drugs instead.

When the mother-of-three asked fans about their opinions, she received an array of negative comments mostly expressing concern for her children. Some fans thought that the only reason she passed her drug test was her abuse of prescribed medication. The judge handling her case was informed of her prescription, that's why "Teen Mom 2" star Leah Messer wouldn't get in trouble by taking it.

The said prescription is believed to be for her migraine. Some fans have become wary allegedly because her current behavior seems different from what she exhibited in seasons five and six of the show.

Inquisitr previously reported that Corey Simms mandated his ex-wife to take the drug test as part of their custody battle for the twins. The MTV star appeared to be dissing her former husband on Twitter and recently, she likewise shared a Mother Teresa quote which she claimed reminded her to be kind regardless of how "unreasonable and self-centered" people are.

Nonetheless, even if "Teen Mom 2" star Leah Messer thinks Corey Simms is not on her side, he clarifies that his only concern is his daughters. In a promo clip for the show, Corey Simms talked to his father about his woes.

"Leah took the drug test that I asked for," he told his dad. "I was just worried [of her] driving down the road jacked up with the girls in the back."

He also said in the clip that he's not doing things to appear mean. What he wants is to ensure that his daughters are getting the best.

"All the stuff I'm doing, I'm not doing it to be a pr--k ... [It's] just to give them the best lives possible."
