A jury on Thursday convicted a Tennessee man of trafficking methamphetamine in Dawson County.

Samuel Lee Smallwood, 40, of Madisonville was sentenced to 20 years, with the first 15 to be served in prison and the remainder on probation. He also faces fines, fees and court costs totaling more than $350,000 upon his release.

Smallwood was among four people arrested in August 2012 following a traffic stop in downtown Dawsonville.

A search of the vehicle turned up about 1.5 ounces of methamphetamine, as well as prescription pills and hypodermic needles, deputies said.

According to sentencing and probation conditions, Smallwood can have no contact with his co-defendants in the case.

Stephanie Adkins of Gainesville, Joseph Cansler of Sweetwater, Tenn., and Crystal Tyner of Maysville were also initially charged with trafficking.

On Feb. 4, Tyner pleaded guilty to a reduced charge of possession of methamphetamine with intent to distribute and was sentenced to 15 years, with five to be served in prison, followed by probation.

Tyner, 30, also pleaded guilty to possession of three types of prescription pills and a drug-related object. The sentences run concurrent with the possession of methamphetamine count.

Adkins was sentenced to 10 years probation, while Cansler received eight years with 16 months to serve for their involvement, after entering guilty pleas.
