They don't know what it is -- or where it's coming from -- but the Bi-State Narcotics Task Force is trying to get a dangerous drug off the streets of Texarkana. Texarkana, Texas, Police Sergeant Steve Shelley says more than twenty people have had adverse reactions to it over the past month. Shelley says several people who have taken the drug have experienced severe agitation, loss of memory, extreme loss of motor skills, and loss of consciousness for up to four days. He asks anyone who might have any information about the drug to call either Texarkana police department, the Miller County Sheriff's Office, or Texarkana Crime Stoppers.
