Objectives: Compared with nonaddicted controls (CTLs), adults in remission from methamphetamine addiction (MA-REM) evidence impairments on objective measures of executive functioning and impulsivity.

Methods: To evaluate the impact of these impairments in MA-REM adults, demographically matched groups (MA-REM, n=30; CTLs, n=24) completed objective and self-report measures of executive functioning and impulsivity.

Results: MA-REM adults demonstrated significantly (P<0.050) greater objective and subjective problems with executive functioning and impulsivity.

Conclusions: These results suggest that adults in MA-REM are aware of their deficits and that these deficits have significant impact in everyday life.
