Your nose and taste symptoms sound similar to a smell disorder. Parosmia and Phantosmia sometimes can happen from colds or sinusitis. You could lose you sense of smell or start smelling things that aren’t there from damage to the olfactory nerve. Other possible causes are post concussion syndrome, temporal lobe epilepsy, and early stages of Parkinson’s disease and dementia. In any case, you should get this checked out with a doctor to rule out the serious stuff. I have been living with Phantosmia for seven years from a concussion. I use a pure CBD extract with no added oils – it does taste like crap so I put it in food.
While everyone has their own unique body chemistry, it seems like the vast majority of people can ingest CBD oil without ever feeling any unpleasant side effects at all, and the remaining few will mostly likely experience only minor symptoms like stomach upset or dry mouth. Since scientists are using pure extracts from known sources, it’s likely that some consumer reports of headaches or other minor adverse reactions could be due to impurities in inferior CBD products.
