When Myron first encountered the Mordinos, they were farming peyote cacti and selling it to tourists as the "Reno Experience." Unfortunately, as Myron explains, peyote trips last too long, and profit is generated by fast turnaround and a high addiction rate. Furthermore, the climate was far too ravaged and irradiated to grow anything but the hardiest of plants. So, Myron began delving into growing mushrooms. Hallucinogens have low overhead and thrive in plentiful brahmin dung. From there, Myron began experimenting with derivatives of lysergic acid diethylamide, psilocybin and THC. However, the Mordinos still desired something a little harder and more addictive that could aid them in gaining control of Redding. The solution to the problem came from the brahmin fertilizer itself; Myron discovered that the slaves harvesting the drugs were in a constant state of intoxication from inhaling the fumes.
In the pre-War days, big meat companies had experimented with a cheap protein extract for growing food. However, the product had to be abandoned due to contamination from a skin bacterium, which caused it to act like an amphetamine when ingested. By the time this was discovered, tons of the material were irreversibly contaminated, and rather than destroy it, the meat companies fed it to their cattle in an attempt to recoup their losses - these cattle were the ancestors of the post-apocalyptic brahmin.
After exposing slaves to vats of brahmin dung sans the plants they had been cultivating, Myron realized that not only had the intoxicating properties of the protein extract been preserved in brahmin tissues, one did not need to slaughter the brahmin to harvest it - Myron was able to develop a process to refine it from their waste, thus providing the Mordinos with the cheap, addictive and fast-acting drug they had been in search of since they had entered the trade.
About a hundred slaves were killed in initial testing — mostly results of heart attacks, cerebral hemorrhages, and psychotic episodes — but Myron was ultimately successful in producing jet. Thanks to Myron and jet, the Mordino family were able to build their drug empire. Grateful, they supplied their boy-genius with anything he wanted, usually whores and drugs. The Stables research team would further Myron's work, hoping to create a stronger and even more potent version, codenamed jet beta. However, the results were unsuccessful, as they could not quite get the kinks out (e.g., nasal bleeding, hallucinations, heart attacks). But they did increase the duration of its high - from 15 to 60 minutes.
Myron would die less than a year after the Chosen One defeated the Enclave, somewhat ironically stabbed to death by a jet addict while drinking in a bar at the Den. While no one would remember Myron's name - let alone that he had created jet - his creation would live on, even spreading as far as the Capital Wasteland, where Murphy would attempt to produce an even more potent version, named ultrajet, designed for use by ghouls, who are barely affected by standard jet.
Meanwhile, in the Mojave Wasteland, some of the more scientifically enlightened learned about the secrets of ultrajet and sought to make it themselves, and home chemists developed a potent form of jet called rocket.
This more powerful variant of jet was first seen in the Capital Wasteland, created by a ghoul named Murphy. He created ultrajet by combining jet, Sugar Bombs, and Abraxo cleaner. Later, in the Mojave Wasteland, ultrajet is found being sold by NCR Sergeant Daniel Contreras, the only known source in the entire area. How he obtained it remains a mystery. Ultrajet is also available in the Commonwealth.
Ultrajet is harder to get addicted to than standard jet, but the addiction to it is permanent, should someone abuse it too much.
Ultrajet immediately boosts the user's current Action Points by +40, as well as raising their maximum action points by the same amount for 4 minutes, and has a 20% chance of ultrajet addiction. Also, ultrajet use will not alleviate or cause jet addiction and vice versa.
