Washington (AP) Officials say there are fewer methamphetamine labs and fewer users around the country thanks to crackdowns on the chemicals used to make the drug.
A study released by Quest Diagnostics says that the number of workplace employees who tested positive for meth dropped 22 percent last year.
All regions of the country have seen a drop in meth use except the northeast, where use remained steady.
Federal officials have also issued a report saying the number of illegal meth lab seizures plunged 31 percent.
Federal officials say while the number of U.S. meth labs dropped, they have been replaced by “superlabs” in Mexico and mexican-run labs in some U.S. border states.
The quest report also found cocaine use in the general work force fell by 19 percent in 2007, the biggest single-year decline in a decade.
