Is vinegar the same as alcohol? if i can't drink due to medication interactions and health reasons, can i have apple cider vinegar safely?

Has no alcohol, safe: Vinegar does not contain alcohol. It has acetic acid, a very different chemical. It is very safe though should be diluted before consuming. There are no proven drug interactions; some sites say large amounts might interact with digoxin, insulin and diuretics because it can lower potassium, but it contains potassium so I doubt that.
