Can a threshold for 11‐nor‐9‐carboxy‐Δ9 ‐tetrahydrocannabinol in hair be derived when its respective concentration in blood serum indicates regular use?

A 100 μg/L or higher concentration of 11‐nor‐9‐carboxy‐Δ9‐tetrahydrocannabinol (THC‐COOH) in blood serum is generally assumed to be associated with regular and/or heavy use of cannabis. At present, determination of the extent of cannabis use by means of the concentration of THC‐COOH in hair has not been assessed. Therefore, we aimed at establishing a threshold for THC‐COOH concentrations in hair to prove frequent consumption by comparing THC‐COOH concentrations in 129 corresponding serum and hair samples, respectively. The concentration of THC‐COOH in the serum was analyzed by gas chromatography–mass spectrometry and in the hair by liquid chromatography–tandem mass spectrometry. Data were statistically evaluated using receiver operating characteristic curves and contingency tables. Our results suggest that a THC‐COOH concentration of ≥4.2 pg/mg in hair was always accompanied by a THC‐COOH concentration of at least 100 μg/L in blood serum. Should this be confirmed by further studies of a larger study population, a hair concentration of 4.2 pg/mg THC‐COOH can be set as a threshold to predict regular and/or heavy consumption of cannabis even if no corresponding blood sample is available for analysis.     

Neuropsychological training and practices with hispanics: A national survey

Abstract

A comprehensive survey was conducted among neuropsychologists in the United States to examine the past training and current practices of respondents with Hispanic populations. The results indicated that clinical neuropsychologists in the US provide both assessment and treatment services to Hispanics, yet report inadequate preparation to work with this population. Generally, these neuropsychologists did not consider themselves competent to work with Hispanics and requested additional training in the provision of services to Hispanics. In addition, (1) the respondents believe that clinical neuropsychology has paid little attention to cultural factors; and (2) respondents reported that they had virtually no exposure to Hispanic clinical supervisors. The best predictors of self-rated competence for work with Hispanics were related to clinical training. The findings are discussed in light of future recommendations for training and research.
