A: Methamphetamine has limited medical uses for the treatment of narcolepsy, attention deficit disorders, and obesity.

Q: What are the dangers of clandestine methamphetamine laboratories?

A: The production of methamphetamine requires the use of hazardous chemicals. Many of these chemicals are corrosive or flammable. The vapors that are created in the chemical reaction attack mucous membranes, skin, eyes and the respiratory tract. Some chemicals react dangerously with water and some can cause fire or explosion.

Q: Doesn't much of the methamphetamine in the U.S. come from Mexico?

A: The transportation of methamphetamine from Mexico appears to be increasing. There are an increasing number of seizures along the U.S.-Mexico border. The amount of methamphetamine seized at or between U.S.-Mexico border ports of entry (POEs) increased more than 75 percent overall from 2002 (1,129.8 kg), to 2003 (1,733.1 kg), and 2004 (1,984.6 kg). This increase most likely reflects the increased methamphetamine production in Mexico since 2002. Drug trafficking operations in Mexico primarily smuggle methamphetamines into the U.S. in Arizona and southern Texas.

Q: Can the waste from methamphetamine laboratories be dangerous?

A: Methamphetamine manufacturing results in a great deal of hazardous waste. Making one pound of methamphetamine generates six pounds of waste. This waste include corrosive liquids, acid vapors, heavy metals, solvents and other harmful materials that can cause disfigurement or death if they come in contact with the skin or are inhaled into the lungs. Lab operators almost always illegally dump this waste in ways that damage the environment. National parks and other preserved sites have been adversely affected.
