Human snacks have been part of our culture since the the portal to Earth opened. Popularized over the last 5 years by music and mass media, these human creations invade all aspects of society.
An estimated 208 thousand ponies internationally consume illegal snacks. In Equestria, results from the 1020 Holistic Oral Repast Section of Equine Fertile Engestable(sp) Equestrian Department showed that 19.9 thousand Equestrians (or 8% of the population aged 12 or older) used illegal snacks in the moon prior to the survey.
