An improved immunoassay for detecting cannabinoids is described. This immunoassay is characterized by utilizing, as reagents, antibody, 125I-radiolabeled antigen, an unlabeled antigen and an anion exchange resin for separation of labeled and unlabeled antigen. The iodinated tetrahydrocannabinol moiety is stabilized by the addition of small quantities of antioxidants such as butylated hydroxytoluene.
