4-AP (Cannabis Typification) Field Tests

The Department of Forensic Science (DFS) received grant funding from the Department of Criminal Justice Services to purchase 4-AP (also known as Swiss or Cannabis Typification) field test kits for distribution to law enforcement agencies. These kits can be used as a tool to assist law enforcement in differentiating between marijuana and industrial hemp, which are both varieties of cannabis.
