A former pharmacist entered guilty pleas Monday to charges of possession of a controlled substance, practicing medicine without a license, unlawful possession of a prescription drug and theft.

Kenneth E. Adams, 41, of Brigham City, appeared before 1st District Judge F. L. Gunnell for arraignment on 20 criminal charges, eight of them felonies. But following plea-bargain negotiations, Adams entered guilty pleas to four charges in exchange for the dismissal of the remaining 16 counts.Two of those guilty pleas are third-degree felonies, and Adams could be sentenced up to 10 years in prison.

The former K mart pharmacist lost his license after police investigated a tip from one of Adams co-workers. He remains free from the Box Elder County Jail in lieu of a $20,000 bond.

Adams had been charged with eight felonies, including three counts of possession of a controlled substance, two counts of possession or distribution of a controlled substance, two counts of practicing medicine without a license and one count of theft.

He was also charged with 12 Class A misdemeanor charges of unlawful possession of a prescription drug.
