Judge Sul Ozerden also order Regina Cooper, 44, of Gulfport, to pay $2,500 and to serve eight months of that sentence under house arrest. She also will have to enroll in a drug-treatment program.
Cooper pleaded guilty to misprision of felony. She cried at the sentencing and expressed remorse for her crime. In exchange for her plea, other charges were dropped.
Her husband, David Cooper, 44, pleaded guilty to possession with intent to distribute the anti-anxiety drug alprazolam, the generic of Xanax. His sentencing is set for later this week.
He faces up to five years in prison and up to $250,000 in fines.
Authorities arrested the couple on federal charges of conspiring to distribute meth, Ecstasy, alprazolam and synthetic narcotics similar to Spice or bath salts.
Court records say the couple conspired to distribute the drugs in Harrison County between December 2012 and June 23, 2014.
An agent with the Mississippi Bureau of Narcotics assigned to Homeland Security Investigations said David Cooper's customers included some members of the military who asked for synthetic drugs because they don't show up in drug tests.
Authorities arrested the couple in May 2014 after authorities at a New York airport intercepted a package of drugs shipped from India and addressed to David Cooper.
Other packages containing drugs that went to the couple's home came from other countries, including China and Pakistan.
At their home, agents seized various drugs and equipment to sell and distribute the drugs.
In addition, authorities found a video of David Cooper manufacturing drugs with a small child shown in the footage.
Assistant U.S. Attorney John Meynardie prosecuted the case.
