Abstract

This study examines the characteristics and geographical distribution of clandestine methamphetamine laboratory seizures in Oklahoma during the height of the clandestine manufacturing problem and after legislative restrictions on precursor chemicals were implemented. Data on clandestine laboratory seizures in Oklahoma from 2001 to 2005 were analyzed to understand the characteristics of laboratories with regard to seizure location, laboratory size, laboratory type, manufacturing processes, and type of equipment utilized. County-level thematic maps of the geographical distribution of laboratory seizures before and after the passage of legislation placing restrictions on the sales of precursor chemicals across the state are presented.
