Hemp & Cannabinoid Science / Interaction checker

Interaction checker

Mechanism-based, not a list of pairs: the engine models what a substance does to the enzymes and transporters that clear everything else, which is why it can say something useful about combinations nobody has typed into a database.

Comma-separated. Prescription drugs, supplements, plant preparations, foods and seasonings — the last three are exactly what does not come up in a clinic visit.

Absence is not safety. A substance or a pair that is not in this section was not checked and is not thereby safe. This is a curated mechanism reference built from primary literature and regulatory reference works — not a comprehensive interaction database, and not a substitute for a clinician or a pharmacist.

What a clean result means

A clean result means NO DOCUMENTED INTERACTION IN THIS DATASET. It does not mean safe, and it is not a clearance. Most substances are not in this dataset at all, and for many pairs that are, nobody has ever studied the combination.

101 substances, 33 mechanisms, 101 citations. Last reviewed 2026-09-09.

The rest of the library

Interaction checker (full dataset) The whole mechanism engine — MAOIs, serotonergic drugs, the CYP axis, P-gp, tyramine, and now the endocannabinoid enzymes and CB1/CB2 from this section. Oilahuasca & allylbenzene metabolism The CYP-mediated allylbenzene shelf: the same phase-1 enzymes read from the other direction, with the MAOI and 2C-series pharmacology attached. Herbs & the temple pharmacopoeia The botanical shelves this section's monographs were drawn from — kava potentiators, the Van Kush pharmacopoeia, ethnobotany. Psychedelics & harm reduction Dose ranges, testing, set and setting, aftercare and emergency guidance, with the same sourcing discipline.
