PEA is another trace amine with a short half-life (~4 s), oxidized by the oxidireductase CYP3A4...the same that metabolizes caffeine and theobromine. to my knowledge, chocolate lacks any RIMA of subtype A and B. Before I formally studied metabolism,
I thought xocolatl infusions would potentiate the mushroom experience; I asked dr. strassman, and he said he didn't know.
There must've been another ingredient added (besides chile peppers).
The late (and wonderful) Dale Pendell covered this, in his own way, in the second volume of his Pharmako* trilogy, PharmakoDynamis. One associated plant that comes up as an admixture with unanswered questions attached has the Latin name
Quararibea funebris, but besides this unusual ingredient and the aforementioned chillies, the commonest flavourings were allspice (
Pimenta racemosa) and vanilla. Pendell wrote plenty more on the
cacahuatl preparation methods of the Aztecs but this tangent has continued long enough lest I reproduce Pendell's entire
Theobrome cacao chapter here.
One more relevant point he raises, however, is that chocolate "contains two related compounds, in greater quantities, that inhibit the natural degradation of anandamide in the body." This, to me, suggests some kind of FAAH inhibitor which surely must be pharmacologically relevant. Considering phytochemical compounds in isolation is prone to errors of emission in this respect - which brings me to a further point: bearing in mind that PEA is metabolized by, amongst other things, CYP3A4, and that purine alkaloids found in chocolate are also substrates for this enzyme, we can also surmise that the half-life of PEA likely will also be prolonged (slightly) through competitive inhibition.
Add to that the abundant flavonoids and catechins found in (good quality) chocolate and their metabolic effects and we might start to see a broader picture. It would be reasonable to suspect that flavonoids would modulate the metabolism of
Psilocybe fungal alkaloids, for example.

In "The Simple Plant Isoquinolines", Shulgin & Perry list 4,6-dihydroxy-2-methyltetrahydroisoquinoline [1], longimammidine (8-hydroxy-2-methylTHIQ) [1] and salsolinol (6,7-dihydroxy-1-methylTHIQ) [2] in association with Theobroma cacao. Whether any of these compounds have any bearing on the subjective effects of commercial chocolate remains to be seen. Their occurrence might be restricted to the roots, for example.
