I've found it to dull visuals when paired with serotonergic psychedelics, but harmaline is an MAOI and acetylcholinesterase inhibitor, so it doesn't share the same mechanism by which it functions. Lotus went well with ketamine and PCP but did dull the visuals to the same degree 10-20mg of Valium would.Does it have synergy with psychedelics? It seems like it from what you say but it's also 5ht2a antagonistic... I wouldn't want to ruin a trip accidentally if it killed my visuals yk?
I'd argue that the same scale of dulling visuals happened with Miprocin and LSD but not any phenethylamines I tried. It left MDA, MDMA, allylescaline, 25C-NBOMe, DOM and 2C-B completely unscathed for some reason.
Cannabis also helped the visuals to return a bit, which was interesting. Lotus seemed to intensity the psychedelic headspace for some reason, especially with ketamine and PCP.
