First analytical chemistry study on drug abuse in the Buenos Aires (Argentina) University students

Abstract

One hundred samples were randomly selected from urine specimens collected from Buenos Aires University students, 50 males and 50 females, whose ages ranged from 19 to 47 years. Cocaine (COC), cannabinoids (CNNs), amphetamines (AMs), benzodiazepines (BZDs), barbiturates (BBTs), opiates (OPs) and salicylates (SAs) were searched for by ELISA, FPIA, normalized TLC, HPLC and GC/MS techniques. The presence of COC was detected in five samples, CNN in two and SA in twelve. No evidence of AMs, BZDs, BBTs or OPs was found.
