title: [Accumulation and stability of drugs in hair].
abstract: The transfer of cocaine and methadone into and out of human hair was investigated in vitro. A transfer in either the one or the other direction could not be observed. In addition the drug concentrations in hair obtained form addicts at different distance from the scalp were determined. The results demonstrated a decrease of the drug levels from the proximal to the distal parts of the hair. The dimensions of the decrease varied within wide ranges.
