Are meth labs really dangerous?

Yes. Meth is made from easily obtained hazardous chemicals, such as acetone, anhydrous ammonia (fertilizer), ether, red phosphorus, and lithium. Toxicity from these chemicals can cause explosions if not used properly and can remain in the lab long after it has been shut down, causing a wide range of damaging effects to health. Because of these dangers, the U.S. Environmental Protection Agency has provided guidance on cleanup of methamphetamine labs.
