Abstract

A binding partner, especially an antibody fragment that specifically recognizes an antigen-antibody immune complex between anti-THC and THC (tetrahydrocannabinol), is disclosed. The binding partner facilitates a non-competitive homogenous immunoassay for detection of cannabis use. A test kit comprising the binding partner is also described. Preferably the immunoassay is applied for roadside testing of saliva from suspected drivers.
