[Determination of morphine in human hair (author's transl)]

Detectable amounts of morphine are apparently deposited in the hair of the head after long-term abuse. In 10 of 20 drug-induced deaths investigated it was possible to determine morphine values between 0.1--1 mg/100 g of hair with the appropriate preparation and application of sensitive, specific techniques. The method is suitable to prove prolonged abuse of morphine or heroin.
