DRUG DISTRIBUTION IN THE HEAD, AXILLARY AND PUBIC HAIR OF CHRONIC ADDICTS

This study investigates the distribution of some drugs in hair samples taken from different parts of the body (head, pubis and axyllae). Sam ples drawn from 15 subjects who died from drug overdose were analysed. The concentrations of the drugs detected in the biological fluids did not appear to be correlated with the those present in hair. The highe st drug levels were observed in pubic hair. The concentration differen ces observed in the various types of hair can hypothetically be ascrib ed to a likely incorporation of the drugs from the outside.
