"Teen Mom 2" star Leah Messer is no stranger to controversy. The assumptions and hints of drug use have gone on for years. The rumors of bad behavior seem to follow this mother of three. In 2014 when she was splitting with her second husband Jeremy Calvert, he accused her of cheating and filed for divorce. A few months later, Messer did seek treatment for anxiety and depression. Some believe she had actually sought treatment for drugs instead.

During that same time, the "Teen Mom 2" cameras were rolling when Jeremy met with Leah's first husband Corey Simms.

Both of the men were concerned about her alleged drug use, and prescription pills were mentioned. The possible drug use was brought up again when Simms was talking to his wife. As for Leah Messer, she denies the whole thing and says there was no drug use or treatment.
