Symptoms experienced by law enforcement personnel during methamphetamine lab investigations

This study was conducted to determine if law enforcement personnel experience symptoms associated with methamphetamine lab investigation and to assess those factors that may result in more symptoms. A total of 258 standardized, self-administered surveys were distributed to law enforcement personnel attending national/regional training classes, between June 2004-February 2005. Ninety-three percent of the surveys were returned and used to determine symptoms experienced while investigating clandestine methamphetamine labs, as well as the job duties of the respondent and the personal protective equipment used. More than 70% of respondents reported headaches, central nervous system symptoms, respiratory symptoms, sore throat, and other symptoms. Unadjusted and adjusted risk of symptoms was higher for those who investigated more than 30 labs. Other significant risk factors included time spent in the lab, phase of investigation, presence of active chemical processes, and coexistent disease. Respirator use was not independently associated with the likelihood of reporting symptoms. It was concluded that methamphetamine lab investigation is positively associated with symptom reporting in a high percentage of law enforcement personnel involved in these tasks. For most individuals, the reported symptoms were transitory and diminished in a short time, but some individuals reported needing to seek medical attention with symptoms that persisted.
