It was investigated in Japan in 1950s. The l-isomer showed weak analgesic action comparable to codeine and antitussive action far weaker than codeine. The d-isomer showed no such activity but caused seizures in rats.
It was abused in Japan during the 1950s. In a small study in 1989 it showed some effect against opioid withdrawal symptoms without causing withdrawal symptoms itself. It was concluded that it may be an opioid partial agonist.
It has been abused in Europe, in 1989 a small study of 15 abusers and some volunteers found, that it had some partial similarity to opioids, that it produced withdrawal symptoms and had dependence and abuse potential to a certain degree.
The Canadian Controlled Drugs and Substances Act was amended in 2016 to include the substance as a Schedule III substance. Possession without legal authority can result in maximum 3 years imprisonment. Further, Health Canada amended the Food and Drug Regulations in May, 2016 to classify Lefetamine as a controlled drug.
Some related pyrrylphenylethanones had analgetic activity comparable to morphine. Some pyrrole analogues were reported to have analgesic effects comparable to lefetamine and being devoid of neurotoxic properties.
