A chocoholic is a person who craves or compulsively consumes chocolate. The word "chocoholic" was first used in 1968, according to Merriam-Webster. It is a portmanteau of "chocolate" and "alcoholic". The term is used loosely or humorously to describe a person who is inordinately fond of chocolate; however, there is medical evidence to support the existence of actual addiction to chocolate. Psychoactive constituents of chocolate that trigger a ‘feel-good’ reaction for the consumer include tryptophan and phenylethylamine, which may contribute to cravings and addiction-like responses, particularly in people with specific genetic alleles. The quantity of sugar used in chocolate confections also impacts the psychoactive effects of chocolate.
