That's pretty interesting with your tinnitus. Not sure what to say about the DMT-ganja connection.
When I first started smoking weed, I would get incredibly higher than all my friends. They would say (strangers too) how they had never seen someone get so high off of just weed. I wasn't getting as far as you, but my face would contort and spasm involuntarily, my eyelids would glue themselves shut, and I wouldn't be able to open them (with will - I could peel them open with my fingers if I wanted to). One time I wondered why I couldn't see, and they had to tell me it's cause my eyes were shut. It would get pretty ridiculous, but I loved the feeling of conditionally losing control. Even before taking any psychedelics, when I would get really high I would see clouds of color in the air, or get taken on a big mental trip through the imagination, but it ultimately all falls short of true psychedelic experience - most of which falls completely short of the front gate of DMT's playground.
