Hello!! My grandfather, age 87, has menieres disease. He has tried conventional medicine and nothing has helped. His dizziness has gotten so bad it is constant. I am trying to figure out what strand/ kind he should try. He won't be able to smoke it so it would have to be in pill form or an oil? Are there any suggestions that would also not include THC. He has never gotten high in his life and not sure how he would handle it. Thanks for any suggestions. I am very concerned.
