Rolling meth lab
A rolling meth lab is a transportable laboratory that is used to illegally produce methamphetamine. Rolling meth labs often go where the strong, toxic fumes of methamphetamine manufacture cannot be detected, and where the toxic byproducts thereof can be discarded they sometimes are designed to render the drug while the lab travels in a vehicle.
The process of "cooking" methamphetamine involves poisonous, flammable, and explosive chemicals: in November 2001, a rolling meth lab that was carrying anhydrous ammonia exploded on Interstate 24 in southwest Kentucky, prompting law enforcement to shut down the freeway, which backed up for miles. Such incidents as this one have injured the meth producers, passing motorists, and police officers, who are also exposed to dangerous fumes.
Toxic effects and dangerous remnants
As with a home lab, so the remaining fumes from a crude moving methamphetamine lab can be extremely toxic. The surfaces of the vehicle's interior can be coated or impregnated with the poisonous residue, rendering the vehicle worthless. Vehicles stolen for the single purpose of manufacture of the drug are most often considered contaminated and unusable: These remaining by-products often are so dangerous as to prevent decontamination. The "cooking" methods for meth frequently change; the proper remediation for a given lab site therefore cannot be assumed from previous known lab methods. Law enforcement Hazmat teams, who are assigned to dispose of the toxic materials, must be cautious and regularly train.
Law enforcement and detection
Rolling meth labs can be concealed on or in vehicles that are as large as 18 wheelers or as small as a motorcycle. Rolling labs are more difficult to detect than stationary ones and can be often hidden amidst legal cargo on big trucks. Many recent rolling lab discoveries were the result of an officer just "stumbling" onto them. Improved officer training and checking suspiscious vehicles with K-9 units may allow increased detection.
