Arrests in the tri-cities for those found to be in possession of syringes for drug use is rising. Two separate arrests made this week. How do officers determine a syringe used for valid purposes and those that are drug paraphenalia? It is a tricky situation according to Assistant Chief Craig Fillers with Greenville police department but officers to have some useful techniques to differentiate. If you have true medical need for carrying a syringe, no worries, they are legal unless they are filled with an illegal substance or have a residue from being used on the needle, or they are accompanied by a variety of other drugs and paraphernalia not prescribed to an offender.
