Abstract: Drugs of abuse (e.g. cocaine) and related substances are selectively bound by an adsorbent which comprises units derived from carboxylic acids of formula A or B: (A): R1R2C(CF3)-CO2H; (B): R3=C(CF3)-CO2H or derivatives thereof. The adsorbent may be a polymer, or a solid support onto which the carboxylic acid, derivative or polymer has been grafted. The preferenced acid is 2-trifluoromethyl acrylic acid. A drug can be selectively bound from a mixture, and recovered using an eluant comprising an organic acid.
