The Effingham County Sheriff’s Office Drug Suppression Unit initiated a criminal investigation in July regarding illegal drug activity at a Guyton Low Ground Road address after receiving information the occupants were involved in the manufacturing and sale of marijuana, marijuana-infused candy, heroin and LSD. The investigation resulted in the execution of a search warrant Thursday morning. The search resulted in the seizure of marijuana plants and grow chambers from inside the residence. Marijuana plants were also seized outside the residence.
