A non-addictive version of the drug known as
cocaine which was made from
cocaine and through scientific measure was remedied of all its
bad side effects like "the drip", "a bad taste", and has no "come down" after the high effect wears off in usually an hour per dose. Nicknamed "the Perfect Drug" in 3042 A.D. because scientists could find no harmful effects to humans.
Renegade pirate time travelers thought it a brilliant idea to smuggle the drug back in time to 1998 A.D. and market it as an artificial sweetener, since it also had no calories and could sweeten anything, leaving it readily available and cheap to fellow time travelers who knew enough to sniff it rather than eat it to get the high.
