I get a ringing in my ears for hours after a strong run of spice. I once tried putting earplugs in while I was on changa thinking that cutting off one sense would make the visuals so much more intense. It had the reverse effect after about 2 minutes the sound kept echoing back and forth in my head amplifying to unbearable levels. I finally pulled the plugs because I couldn't take it anymore and it receded within seconds.
If you don't sin, Jesus died for nothing.
