The Eighth District Court of Appeals reversed defendant's convictions for possession and trafficking of heroin. The police officers' testimony that residue on a spoon and wax paper was probably heroin was not sufficient to prove the substance was actually heroin. A laboratory test was required. Case law holding that an experienced officer may identify a substance as marijuana did not apply. State v. Titsworth, 2005-Ohio-1962, April 28, 2005.
