Concerns regarding chemical contamination associated with the clandestine production of methamphetamine have been realized for some time. (1 – 10) Work conducted by National Jewish Medical Center Researchers has documented a number of the contaminants generated at clandestine laboratories and the presence of some of these contaminants in actual methamphetamine laboratory investigations.(11)

Research conducted by our group has indicated that the contamination associated with these clandestine methamphetamine laboratories does not end when the laboratory ceases operation.(11) Simulated methamphetamine cooks conducted by our group have demonstrated that a number of compounds may persist after the cook has been completed. Initial testing revealed that shortly after a clandestine cook, levels of iodine, hydrogen chloride, and methamphetamine were found at the site even though the bulk chemicals may have been removed. The largest contaminant was found to be the drug, methamphetamine, itself. Methamphetamine was found to aerosolize during the salting-out phase conducted during all current production methodologies. It is released as an aerosol and can contaminate most surfaces within a structure.(11) Our research also indicated that the methamphetamine continues to be present within the structure for some period of time (months to years).

The levels of methamphetamine found within a structure after clandestine cooks is a factor of the type of cook and the number of cooks conducted. Red phosphorous cooks appear to result in a higher concentration of methamphetamine release than do anhydrous ammonia cooks and multiple cooks will result in a higher contamination level.(11) Surface wipes for methamphetamine were collected at suspected methamphetamine laboratories during law enforcement actions. A total of 14 suspected laboratories were sampled with all of the laboratories having at least one sample positive for methamphetamine. The levels of methamphetamine found ranged from a low of 1.0 μg/sample to a high of 16,000 μg/sample. The overall mean methamphetamine contamination level in these suspected laboratories was 511 μg/sample with a median contamination level of 28 μg/sample.
