Ultrajet

Ultrajet is a stronger version of the drug Jet.

Ultrajet is a concoction of Jet, sugar bombs, and Abraxo cleaner, synthesized by the ghoul Murphy. Ultrajet offers 40 action points compared to the 30 from regular Jet, and their use can be 'stacked', allowing a total of 70 extra action points if both are used. As they are different drugs, Ultrajet addicts won't be alleviated of the negative effects of Ultrajet addiction if they use regular Jet, or vice versa. While the addiction rate of regular Jet is 50%, the rate of Ultrajet is only 20%.

Fallout 3
A Ghoul named Murphy, located in Northwest Seneca Station, produces and sells Ultrajet. His supply is limited: he will only sell one Ultrajet for every 8 boxes of Sugar Bombs brought to him.

Fallout: New Vegas
Ultrajet is regularly stocked and sold by NCR Sergeant Daniel Contreras. The drug is not sold by any other vendors, nor can it be found in other locations; Contreras is the only source of Ultrajet in the Mojave Wasteland.

Appearances
Ultrajet appears in Fallout 3 and Fallout: New Vegas.
