| abstract |
A carrier for detecting drug abuse compounds which changes color upon contact with such compounds. Metabolites of abusable drugs such as natural opiates, i.e., morphine and heroin, are qualitatively and semi-quantitatively detected in physiological fluids by the use of the carrier which has been treated with certain stain-producing components adapted to react with the dug abuse compound residues to form colored products and which may be enhanced by intense light and/or heat. |
