TDIQ, also known as MDTHIQ or MDA-CR, is a tetrahydroisoquinoline drug used in scientific research, which has anxiolytic and anorectic effects in animals. [1] [2] It has an unusual effects profile in animals, with the effects generalising to cocaine and partially to MDMA and ephedrine, [3] but the effects did not generalise to amphetamine and TDIQ does not have any stimulant effects. [4] It is thought these effects are mediated via a partial agonist action at α2-adrenergic receptors, and TDIQ has been suggested as a possible drug for the treatment of cocaine dependence. [5]
