Some info on neurocotics, because Emilena is gonna start demanding questions from Sanjay soon:
As mentioned, they are an artificial hybrid drug, hormone, and synthetic cell complex. There are many different types, and each one is designed to do some sort of permanent, irreparable personality or phisiological damage, usually through physical manipulation of brain or body chemistry. They are among the most expensive illegal drugs on the planet, and if not made with the highest quality standards have a good chance of causing retardation, cessation of brain activity, or death.
Normally, an individual is supposed to fall asleep when the patch does it work, but Emilena is just badass.
"Luckily" for her, her patch was made by a wealthy foreign cartel, and is only causing its intended effect: physical enlarging of the hypothalamus and overactive testosterone production, which are both causing crippling libido. It's mainly used by unscrupulous husbands on their unsuspecting wives, and carries the same urban legend connotations as "waking up in a bathtub full of ice with your kidney missing" does today.
