Anyone else experience mild temporary tinnitus after smoking spice?

My lab rats all complain of this. It seems to last anywhere between a few days to a fortnight after smoking, and each burst of high pitch noise is only heard for a few seconds

I would speculate it has to do with blood pressure and crossing over into another dimension.

I gte this after I take the mushrooms and am trying to fall asleap..and the ringing turns into all sorts of nintendo noises at times when I start to drift..I wouldn't worry..prob just neurological noise you are heaing in a hightened sensory state.
