An extremely powerful, fictional drug
used by people throughout Kim Stanley Robinson
's Mars Trilogy
First mentioned usage is by John Boone
on page 239 in Red Mars
"In fact he took a break
and went back to the bathroom in his room to swallowed
a capsule manufactured by Vlad's medical group on Acheron.
It was a drug they had named omegendorph, a synthetic
mix of endorphins and opiates they had found in
the brain's natural chemistry, and a better feel-good drug
than Boone would have imagined possible."
