Abstract
In recent years hair has become a fundamental biological specimen, alternative to the usual samples blood and urine, for drug testing in the fields of forensic toxicology, clinical toxicology and clinical chemistry. Moreover, hair-testing is now extensively used in workplace testing, as well as, on legal cases, historical research etc. This article reviews methodological and practical issues related to the application of hair as a biological indicator of drug use/abuse or of chronic exposure to environmental toxicants. Hair structure and the mechanisms of drug incorporation into it are commented. The usual preparation and extraction methods as well as the analytical techniques of hair samples are presented and commented on. The outcomes of hair analysis have been reviewed for the following categories: drugs of abuse (opiates, cocaine and related, amphetamines, cannabinoids), benzodiazepines, prescribed drugs, pesticides and organic pollutants, doping agents and other drugs or substances. Finally, the specific purpose of the hair testing is discussed along with the interpretation of hair analysis results regarding the limitations of the applied procedures.

Abstract
A sensitive and specific method for the quantitative determination of morphine in human plasma is presented. Morphine was extracted from plasma by solid phase extraction on C18 and converted to its pentafluorobenzyl carbonate trimethylsilyl derivative. The derivatives were analysed without further purification. Using gas chromatography/negative ion chemical ionisation mass spectrometry, a useful diagnostic fragment ion at m/z 356 is obtained at high relative abundance. Deuterated morphine was used as internal standard. Calibration graphs were linear within the range 1.25 to 320 nmol/L. Intra-day precision was 3.82% (15 nmol/L), 2.85% (75 nmol/L) and 4.13% (225 nmol/L), inter-day variability was found to be 1.77% (15 nmol/L), 4.95% (75 nmol/L) and 9.88% (225 nmol/L). Inter-day accuracy showed deviations of 2.18% (15 nmol/L), -0.72% (75 nmol/L) and -0.13% (225 nmol/L). The method is rugged and robust and has been applied to the batch analysis of morphine during pharmacokinetic profiling of the drug.

Abstract
In order to establish an analytical method for the determination of phenobarbital (PB), phenytoin (PPH) and their hydroxylated metabolites in hair, animal model experiments were performed. Five male dark-agouti pigmented rats, aged 5 weeks, were intraperitoneally and orally administered PB or PPH independently at 25 mg/kg once a day for 5 successive days. The growing back hair was collected 15d after the first administration. Four typical extraction methods, using NH4OH-methanol-acetone, TFA-methanol-acetone, 1M sodium hydroxide and proteinase K, were evaluated using the rat hair samples containing PB or PPH. Methanol-acetone-NH4OH (10: 10: 1) was the best extraction method from all aspects, such as high extraction efficiency and low noise. The analytes in the extract were methylated in acetonitrile with 20% tetramethylammonium hydroxide and methyliodide at 70 degrees C for 10 min. After purification with Bond Elut Certify, the methylated products were analyzed by GC-MS. From rat hair, PB, p-hydroxy PB, PPH and p-hydroxy PPH were detected at average concentrations of 26.9, trace, 4.2 and 0.4 ng/mg with an intraperitoneal (i.p.) injection, and at 30.9, trace, 4.0 and 0.4 ng/mg with oral administration, respectively. There was little difference in hair concentrations between i.p. injection and oral administration. This method was applied to the head hair of two patients who orally took toxic amounts of PB and two volunteers who orally took 100 mg of PPH daily for 5 d. The hair concentrations of PB in the two patients were 16.2 and 14.7 ng/mg, and those of PPH in the two volunteers were 3.3 and 0.1 ng/mg.

Abstract
A sensitive and specific method for the quantitative determination of morphine in human plasma is presented. Morphine was extracted from plasma by solvent extraction with ethyl acetate and derivatized to its heptafluorobutyrate derivative. The derivatives were measured by gas chromatography-negative ion chemical ionization mass spectrometry without any further purification. Using this detection mode, a diagnostic useful fragment ion at m/z 637 is obtained at high relative abundance. Deuterated morphine was used as an internal standard. Calibration graphs were linear within a range of 0.78 ng/ml and 50 ng/ml. Inter-assay precision was 2.3% (2.85 ng/ml) and 1.4% (14.25 ng/ml), intra-assay variability was found to be 1.5% (3.71 ng/ml) and 0.5% (14.54 ng/ml). Accuracy showed deviations of -9.3% (2.85 ng/ml) and -4.2% (14.25 ng/ml). The method is rugged and robust and has been applied to the batch analysis of morphine during pharmacokinetic profiling of the drug.

Abstract
This review focuses on basic aspects and recent studies of hair analysis for abused and therapeutic drugs and is discussed with 164 references. Firstly, biology of hair and sampling of hair specimens have been commented for the sake of correct interpretation of the results from hair analysis. Then the usual washing methods of hair samples and the extraction methods for drugs in hair have been shown and commented on. Analytical methods for each drug have been discussed by the grouping of three analytical methods, namely immunoassay, HPLC-CE and GC-MS. The outcomes of hair analysis studies have been reviewed by dividing into six groups; morphine and related, cocaine and related, amphetamines, cannabinoids, the other abused drugs and therapeutic drugs. In addition, reports on stability of drugs in the living hair and studies on drug incorporation into hair and dose-hair concentration relationships have been reviewed. Applications of hair analysis to the estimation of drug history, discrimination between OTC drug use and illegal drug use, drug testing for acute poisoning, gestational drug exposure and drug compliance have also been reviewed. Finally, the promising prospects of hair analysis have been described.

Abstract
A new method for the fast screening of cocaine and 6-monoacetylmorphine (6-MAM) in a single hair, using gas chromatography/mass spectrometry (GC/MS), is described. The analyses are conducted in less than 10 min with minimal sample preparation. The novel method combines the ChromatoProbe direct sample introduction device for intrainjector thermal extraction, fast GC separation, a supersonic molecular beam GC/MS interface and hyperthermal surface ionization (HSI). The technique has been successfully employed for the detection of cocaine in as little as a 1-mm section of hair using selected ion monitoring (SIM). Unambiguous full scan mass spectra of cocaine and 6-MAM were obtained on a single hair for cocaine and heroin users, respectively. HSI was found to be almost 3 orders of magnitude more selective than electron impact ionization for cocaine compared with the major hair constituents, with a minimum detected concentration of approximately 10 ppb in the SIM mode. Results obtained for 12 drugs users showed full qualitative agreement with similar results using rigorous solvent extraction followed by electrospray-liquid chromatography/mass spectrometry analysis. However, quantitative studies showed only partial agreement. No false positives were observed for 10 drugs free subjects. This method enables fast drug monitoring along the hair length which permits time correlation studies.

Abstract
Several techniques have been described for the determination of morphine in hair as a method of monitoring past heroin use. However, although some of the techniques [notably radioimmunoassay (RIA)] may appear relatively simple to perform, any results obtained must be interpreted with caution. In this study, hair specimens from four known heroin abusers were sectionally analysed by a specific RIA for morphine. Prior to analysis, all hair sections were cleaned to remove any possible surface contamination. Five different hair digestion procedures were evaluated to determine the most effective method that could be used to liberate morphine from hair. The greatest analytical recovery was obtained by incubation with 1.0 M sodium hydroxide for 18 h at 55 degrees C, neutralization with 1.0 M hydrochloric acid, and pH adjustment with 0.1 M phosphate buffer (pH 7.0). The morphine concentrations detected in the hair specimens ranged from 0.5 to 13.2 ng/mg of hair. It was also found that the use of shorter length segments (e.g. 1 cm length) gave a clearer, more detailed picture of the historic pattern of heroin use in the four subjects studied.

Abstract
Hair analysis for abused drugs is recognized as a powerful tool to investigate exposure of subjects to these substances. In fact, drugs permeate the hair matrix at the root level and above. Evidence of their presence remains incorporated into the hair stalk for the entire life of this structure. Most abusive drugs (e.g. opiates, cocaine, amphetamines, cannabinoids etc.) and several therapeutic drugs (e.g. antibiotics, theophylline, beta 2-agonists, etc.) have been demonstrated to be detectable in the hair of chronic users. Hence, hair analysis has been proposed to investigate drug abuses for epidemiological, clinical, administrative and forensic purposes, such as in questions of drug-related fatalities and revocation of driving licences, alleged drug addiction or drug abstinence in criminal or civil cases and for the follow-up of detoxication treatments. However, analytical and interpretative problems still remain and these limit the acceptance of this methodology, especially when the results from hair analysis represent a single piece of evidence and can not be supported by concurrent data. The present paper presents an updated review (with 102 references) of the modern techniques for hair analysis, including screening methods (e.g. immunoassays) and more sophisticated methodologies adopted for results confirmation and/or for research purposes, with special emphasis on gas chromatography-mass spectrometry, liquid chromatography and capillary electrophoresis.

Abstract
The accurate interpretation of analytical results from hair testing for drugs of abuse continues to be a complex and difficult problem since many questions still remain unanswered. In this paper an animal model was developed to ascertain the time course for the appearance and disappearance of cocaine and its metabolite benzoylecgonine (BE) in hair. Female Fauve Bourgogne red-haired rabbits (n = 6) were intraperitoneally administered a single dose of cocaine at 5 mg/kg. Animal hair was shaved just before drug administration and the newly grown back hair was subsequently shaved and collected daily over a period of two weeks. Samples were analyzed for cocaine and BE by gas chromatography-mass spectrometry (GC-MS). The profiles were quite similar for parent drug and metabolite. Cocaine and BE appeared in the first sampling (day 1), with peak concentration appearing that same day. 1.01 ng/mg and 0.51 ng/mg for cocaine and BE, respectively. Levels declined rapidly on day 2, remaining detectable for ten days after drug administration. This study demonstrates that the initial incorporation of cocaine compounds in rabbit hair is very rapid (24 h). A small fraction of the drug is detected ten days after exposure, at a time when concentrations in other biological specimens (blood or urine) are not detectable.
