With the Mordino variant off the market and the technique to manufacture methamphetamine at large, new batches flooded the market, becoming a staple recreational and performance-enhancing drug throughout the wasteland.

Drug addictions caused by regular Jet responded to treatment with Fixer and Addictol, increasing their popularity both before and after the Great War. Both stem from the way their Jet alters the perception of reality, to the point that the euphoric rush brought about by the drug is interpreted by the user as the norm and sobriety as the abnormal. Standard Jet is highly addictive, inducing psychological and physical reliance. This was the preferred method of researchers working at the Stables. Jet may also be mixed with saline solutions or other liquids to be delivered intravenously. This requires clean facilities and medical training to do properly, as poor processing will result in contamination and expose users to disease. Wholesale buyers, like Redding in the 2240s, usually receive bulk packages that have to be processed into user ampules first. Jet is typically sold packaged into small, disposable ampules used in metered dose inhalers that deliver the aerosolized drug directly into the lungs of the user, where its is rapidly absorbed into the bloodstream.

The initial euphoric rush rarely lasts more than a few minutes, but the altered state of consciousness makes it subjectively longer for any Jet user. The drug is a powerful meta-amphetamine that stimulates the central nervous system, triggering a rush of energy and strength primarily brought about by endorphins.
