Euphoria is not a separate core emotion. Rather it represents a brief period of intense excitement, bliss, or pleasure that may be genuine or that can be chemically induced. Euphoria provides energy to experience special moments at an intense level but was not designed to be sustained for long periods of time. According to Kent Berridge, an affective neuroscientist, intense euphoria occurs from the simultaneous activation of every hedonic hotspot within the brain's reward system. Substances that can trigger a mild euphoria include tobacco, caffeine, small doses of alcohol (when first ingested), THC, barbiturates and benzodiazepines, amphetamine, methamphetamine, cocaine, MDMA, and methylphenidate , etc. Euphoria may signal early carbon monoxide poisoning (e.g., “choking game). For some, emotionally arousing music, dancing, intense aerobic exercise, or sexual activities, may induce euphoria. It may also be a symptom of specific neurological or neuropsychiatric disorders, such as mania associated with bi-polar disorder. Intense “romantic love” and portions of the human sexual response are also associated with euphoria. More tomorrow.
