Bernard Williams of the Philadelphia Eagles failed the drug test for marijuana. He was suspended from the NFL for six games for using a drug that does not enhance performance. If anything, marijuana would detract from an athletes performance. Let the coach judge Williams performance. 

Another study by the same group assessed the use of fluoxetine (Prozac) (20 mg) in a 7-week open trial in 10 adolescents with the commonly occurring triad of SUD, CD, and major depression (Riggs et ah, 1997). Seven of the eight subjects had significant improvement in mood p < 0.001), and the majority reported that the fluoxetine (Prozac) assisted in their substance rehabilitation. The medication was well tolerated and no interactions between fluoxetine (Prozac) and any substances of abuse were reported. There were no positive drug tests for the duration for the study.

As of early 2002, creatine supplementation was not on the list of banned or prohibited supplements of the International Olympic Committee, the United States Olympic Committee, or the NCAA. However, since nutritional supplements are not closely regulated by the FDA, the United States Anti-Doping Agency (the USADA, which oversees drug testing for the USOC) warns that ingestion of any nutritional supplement is at the athlete s own risk.

Among others, Wieboldt et al. [57] used a similar technique, immunoaffi-nity ultrafiltration, in conjunction with ion spray HPLC/MS, on a small benzodiazepine library tested for binding to a polyclonal sheep IgG antibody. Dunayevskiy et al. [58] used gel filtration together with CE/MS and LC/MS on a small library of drugs tested for binding to human serum albumin, Chu and coworkers et al. [59-61] reported an application of affinity capillary electrophoresis (ACE)-MS to some tri- and tetrpeptide libraries (>1000 compounds)...

The type of anticoagulant used during collection of the blood sample may also affect the stability of drugs tested for or their metabolites. Various chemical agents, such as EDTA, formic acid, acetic acid, sodium fluoride, lithium heparin, potassium oxalate, and methylacrylate have been used to stabilize analytes in biological matrices. ...

Because drug testing for controlled substances bears heavily on a person s reputation, the method to detect controlled substance must be accurate and must follow international guidelines, which advocate a method that must include chromatographic separation to isolate the analyte from other matrix components and mass spectrometric detection with either SIM of three compound-specific ions on a single mass analyzer or with selected-reaction monitoring (SRM) of two specified precursor-product reactions. GC/MS and LC/MS methods that follow these guidelines are used routinely to detect and quantify cannabinoids, narcotics, cocaine, amphetamines, and other substances of abuse [57]. 

Stand-down means the practice of temporarily removing a driver from the performance of safety-sensitive frmctions based only on a report from a laboratory to the MRO of a confirmed positive drug test for a drug or drug metabolite, an adulterated test, or a substituted test, before the MRO has completed verification of the test results.

Morphine is also hepatically metabolized to normorphine by the cytochrome P-450 enzymes GYP 3A4 and CYP2C8. Small amounts of codeine and hydromorphone are also produced, which is not clinically significant but can cause false positive urine drug tests for these substances. Morphine dosage should be reduced in patients with impaired renal function.
