It could be it’s adrenergic or serotonergic effects that precipitates the visuals/visions…kratom also contains rhynocphylline which is an NMDA antagonist but it doesn’t contain much. One thing I am interested in is the combination of kratom and cats claw to add in more rhynocophylline. Hopefully this will allow for less kratom and curb some tolerance the way opiate users use ketamine and DXM etc to lower tolerance.
