In the universe of science fiction epic Dune<\/em>, spice melange, usually just referred to as \u2018the spice\u2019, is a valuable narcotic substance. It\u2019s formed exclusively in the sands of the planet Arrakis from the excretions of young sandworms.<\/p>\n

The spice confers health benefits, for example increasing life expectancy. It\u2019s also highly addictive, creating a vast demand and making it an extremely precious commodity. Whoever controls the spice inevitably holds control over every other faction in the Dune<\/em> universe.<\/p>\n

This may have historical parallels in the real world. As science writer Dr Carol Hart noted in her chapter on melange in the 2008 book The Science Of Dune<\/em>, \u201cIn pre-Columbian America, the coca leaf was, somewhat like melange, largely reserved for the noble and priestly classes of the ancient Incas. In fact, the ruling classes retained their power in part by their monopoly on the coca leaf.\u201d<\/p>\n

Spice also has dramatic mind-altering properties, enabling a post-human species known as the Guild Navigators to see across vast swathes of space in order to guide spacecraft on long interstellar journeys. The Navigators live in tanks, continually inhaling orange spice gas in such quantities that it grossly mutates their bodies.<\/p>\n

Even moderate exposure to the spice stains the entire eye of the user a deep dark blue, a trait seen in the Fremen people of Arrakis, due to their constant exposure to the substance \u2013 and perhaps not unlike the persistent pupil dilation that can accompany real-world recreational drug use.<\/p>\n

The Bene Gesserit are also avid spice users. It imbues them with the power to see into the future \u2013 and heightens their mental abilities, which in a loose sense might mirror the rise today of nootropic drugs, \u2018smart pills\u2019 taken by those seeking a mental edge. Their makers claim the drugs can improve cognitive functions like memory, attention, creativity and motivation. Indeed, they are sometimes prescribed to treat conditions such as ADHD and dementia.<\/p>\n

Yet there is concern over the non-prescription use of nootropics. A 2020 study by the Harvard Medical School in Boston, Massachusetts, found that these \u2018supplements\u2019 can contain drugs not yet approved for pharmaceutical use<\/a>. \u201cUse of these supplements poses potentially serious health risks,\u201d says study author Dr Pieter Cohen<\/a>.<\/p>\n
