Teen Mom Avoids Prison Over Drug Test

Law enforcement sources tell TMZ, the judge ordered Amber to submit to an extra 30 DAYS of daily drug testing for failing to procure a urine sample on Monday -- an automatic "fail" when it comes to drug testing.

And there's more -- we're told Amber didn't just botch a drug test, she also missed an AA meeting recently ... another big no-no, according to the terms of her release.
