The troubled teen has been having such a hard time getting clean, she literally begged a judge to KEEP her in jail for five years!!!
We're now hearing from sources that Amber is addicted to Suboxone, a drug used to treat opiate addiction which blocks the effects of drugs like meth and heroin, but produces a less euphoric high, and is typically used to help addicts detox.
So basically, Amber may have actually been trying hard to wean herself off the bad shiz, but got addicted instead!
Portwood is currently sitting in the slammer as she waits for a judge to decide her fate.
Given her history with drugs, we really hope jail cleans her up.
