Summary
Salvinorin B methoxymethyl ether (2-O-methoxymethylsalvinorin B, or 2-MMSB) is a semi-synthetic analogue of the natural product Salvinorin A which is used in scientific research. It has a longer duration of action of around 2–3 hours, compared to less than 30 minutes for salvinorin A, and has increased affinity and potency at the κ-opioid receptor. Like the related compound herkinorin, salvinorin B methoxymethyl ether is made from salvinorin B, which is most conveniently made from salvinorin A by deacetylation, as while both salvinorin A and salvinorin B are found in the plant Salvia divinorum, salvinorin A is present in larger quantities.

Add to PsychonautWiki Journal
The PsychonautWiki Journal logging app doesn't include every substance. To track Salvinorin B methoxymethyl ether there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:
Salvinorin B methoxymethyl ether Source: SubstanceSearch (substancesearch.com) Smoked dose (µg): threshold 100 · strong 275-425 · heavy 425+ Smoked duration: total 3h Note: ranges are harm-reduction guidance, not a prescription. Start low, go slow, and test your substances.
The app keeps custom substances simple, so the full dose ranges live in the description text above. Ranges are harm-reduction guidance, not a prescription.
Tolerance
Tolerance Decay
Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
