Here is a very interesting item about the percentage of positive tests among federal "safety-sensitive" workers released by Quest Diagnostics and dated 12/1/05. Drug testing home kits were discussed in a recent post but no data was presented about drug test positivity among workers.
The number of federal “safety-sensitive workers” who tested positive for amphetamines jumped about 13% during the first six months of 2005, according to the Drug-Testing Index released by Quest Diagnostics. The tests show 0.35% of federal workers tested positive for amphetamines against 0.31% during the same period last year. In total, 10.2% of all positive drug tests revealed amphetamines, as opposed to 10% a year ago.
Overall, 4.3% of all workers tested positive for some sort of drug in the first six months of 2005 against 4.5 % in 2004. The percentage of workers to test positive for drugs has declined almost every year since 1988, when 13.6% of workers tested positive for drugs. Among those workers who did test positive, 54% were found to be using marijuana, as opposed to 55% a year ago, while 14.4% were found with cocaine in their systems compared with 13.8% a year ago.
Here is another reference to a similar topic dated 9/29/05:
Oregon Medical Laboratories in Eugene, the state’s largest drug-testing laboratory, reports a 30 percent increase in the first six months of this year. Marijuana remains the most frequently detected drug, showing up in more than half of all positive tests. But methamphetamine appears to be the fastest-growing illegal drug of choice among workers.
The actual rate of positive test results that indicate drug use increased to 6.9 percent for the first half of 2005, compared with 5.3 percent during the first half of 2004, lab officials said. The results do not include tests from employers regulated by the U.S. Department of Transportation, such as trucking firms, which have been required to randomly test workers for drugs since 1989 and have lower positive rates as a result.
By the way, there is a booming market on the web for "drug cleansers" which purportedly "cleanse" the body of residual traces of drugs of abuse. Here is a link to a Yahoo search page listing some of the products available on the web.
How would I know if they work?
