"Injected with a Poison" is an example of Belgian techno and runs at the fast speed of 149bpm.[3] It is a remix of the earlier version on the debut Praga Khan featuring Jade 4U single "Free Your Body/Injected with a Poison"(1992), incorporating elements of "Free Your Body" (in particular, Jade 4U's vocals).
Kat Stevens of Freaky Trigger writes that the "intense" song is "spontaneous" and "full of variety" with "at least eight things going on at any time," noting its incorporation of acid squelching, Jade 4U's "whooping" vocals, the disturbing song name vocal samples, piano breaks, as well as what she described as "an underwater electric whisk" and "one of those duck-calling kazoo things."[3] In only four bars, each of the track's constituent parts build ups to a crescendo, before "switching over to something completely different," while the track also sporadically grounds itself with "a quick 4/4 ‘barp-barp-barp-barp’" in order for it "to get its breath back."[3]
The vocals "Injected with a Poison" were sampled from televangelist Robert Schambach.[4]
These vocals include:
"Are you listening to me?"
"Injected with a poison"
"we don't need that anymore"
