** FILE ** Crystal methamphetamine dries on a table at a seized illegal laboratory in Ensenada, Mexico, on Aug. 26, 2009. Although Mexican-made meth is not entirely new to the U.S. drug trade, it now accounts for as much as 80 percent of the meth sold here, according to the Drug Enforcement Administration. Much of it is up to 90 percent pure, a level that far exceeds the potency of most previous Mexican meth. (AP Photo/Guillermo Arias)
