O-Desmethyltramadol (O-DSMT) is an opioid analgesic and an active metabolite of tramadol. While it has limited history of human use, it is accessible through various online research chemical vendors. Compared to tramadol, O-DSMT lacks the stimulant effects and produces sensations more similar to traditional opiates, with higher potency and a shorter duration of action.
O-DSMT is an opioid of the phenylpropylamine class, acting as a highly active metabolite of tramadol with notable sedative and analgesic effects. Its structure, 3-(2-((dimethylamino)methyl)-1-hydroxycyclohexyl)phenol, differs from morphine-based opioids and is structurally closer to codeine. It contains a cyclohexane ring attached to a phenyl ring with an additional hydroxyl group.
Legal Status in the U.S.: O-DSMT is not explicitly controlled at the federal level; however, under certain circumstances, it could be classified as a controlled substance under federal law. State laws vary, so its legality depends on each state’s specific regulations.
