Drug test may mean more troubles for 'Teen Mom' Amber Portwood Madison County Sheriff Departmen / AP "Teen Mom's" Amber Portwood insists she didn't skip a required drug test. On Thursday, a judge will decide if that's really the case. By Josh Grossberg and Katie Rhames, E! Amber Portwood may be in trouble again, this time for failing to take a mandatory daily drug test that was a condition of her probation in her December drug arrest, according to various media accounts. If true, not only would it put her at risk of being sent to the slammer, but she'd also leave behind 2-year-old daughter Leah for the foreseeable future. In an exclusive interview with E! News, Portwood vehemently denied the allegations. MORE: Amber Portwood denied! Judge refuses to let her participate in "Teen Mom" reunion "I would be in jail if I skipped" she told us.
