Pinal County prosecutors say 39-year-old Jennifer Jean Sutton was charged in the case in February.
They say Sutton was indicted on two charges of sale of methamphetamine and possession of methamphetamine. Both are felonies.
Sutton pleaded guilty to both charges and will serve 10 years for each one with the sentences running concurrently.
Authorities say the investigation and resulting arrest was conducted by the Casa Grande Police Department's Narcotics Unit.
