Tinnitus by Charles Andrew
I have found that marijuana is effective for the relief of a constant ringing in the ears. This also allows a good night's sleep. If you look on Medline you will see a story on memantine and tinnitus, by the ENT Dept. in Munich, Germany. I recommend this abstract for the explanation of its action. I would be interested if you can see a similar explanation for marijuana. Tinnitus is an age-related disease that affects 16% of the American population and certainly deserves more attention than it is getting. I can tell you that the loudness is a function of psychological stress and it can even lead to a feeling of vomiting. I hope this helps.
