Has anyone else noticed some flashes of coloured light… sort of like static lightening flashing across the peripheral vision on low or threshold doses?

My only experience of it has been with very small doses of brugmansia leaf smoked with cannabis.  I harvest datura seed when I find them at work, and have smoked the leaf a few times as well but  don’t have enough experience to really say much about that atm.

The brugmansia is at least a useful sedative to have around in micro doses, and what my plants drop alone is more than needed.

I guess next will be some sort of topical ointment, but the real goal there is just to help my old arthritic joints really.
