  • The time-slow has a separate duration to the other effects; time is slowed for 15 seconds, while the other effects last for 25 seconds. This is still less than plain Psycho, which lasts 5 minutes.
  • Despite being a combination of Psycho and jet, Psycho jet can only cause Psycho addiction.
  • Psycho jet can be extremely potent when used with a high damage weapon, giving a fully modified Gauss rifle an astonishing amount of up to almost 500 Damage with 5 Points invested into the Rifleman perk and turning the Big Boy into a weapon capable of killing almost every enemy in the game with one shot on all but survival difficulty. It also applies the damage multiplier to any extra damage the weapon may yield, such as burning or radiation damage.
