Self Diagnosis

Hyperosmia is an increased ability to smell - for example, being able to identify the perfume of the previous occupant of a chair. It is seen in patients with cluster headaches, migraines, and adrenal cortical insufficiency (Addison's Disease), although some people possess it naturally (either through developed senses or increased training). Psychedelic drugs such as LSD, psilocin, or 2C-B have been anecdotally shown to enhance smell.

I just have naturally developed senses.
