Changes

===The Perfect Drug (Edit)===

The original song shortened by fifty seconds to suit radio airplay. Available on radio promos only.

===The Perfect Drug (''We're In This Together'' version)===

From the third ''We're In This Together'' single and international ''Into The Void'' single, this version is same as the original, but does not cut off at the end, rather repeating further and fading out.

===The Perfect Drug ([[Meat Beat Manifesto]])===

This remix is almost a dub mix: it is very light on lyrics and emphasizes the percussion beat of the song. The word "annihilate" is added at some points and leads this remix out of the breakdown and into the ending portion. "The only lyrics in this version are "And I want you" and "You are the perfect drug."

===The Perfect Drug (Plug)===

Incorporating dream-like synths and a danceable rhythm, this remix is notable for its synth rendition of the opening strains of the song. The last few lyrics of the first verse are used, "You are the perfect drug" is heard at the breakdown, and vocal instrumentation has been added. "Take me with you" is repeated at the end of this remix.

===The Perfect Drug ([[Nine Inch Nails]])===

This remix begins with Reznor whispering "You are the perfect drug," distorted and slowed down. A dance beat and wind are added over the vocals to form the first section. The lyrics are then sung about a third of the way through, as the beat becomes heavier and the synths build in volume. By the middle of the song, the music becomes much louder as the lyric "Take me with you" is whispered over it. Vocal instrumentation, albeit distorted, is also incorporated into this remix. Perhaps the most notable aspect of this remix is the use of the "[[Closer]]" synth voice to replicate the melody at the end of the song.

===The Perfect Drug (Spacetime Continuum)===

Windchime-like instrumentation over a percussive beat and the whispered lyric "You are the perfect drug" open this remix. It then goes into a percolating beat, with a simple melody over a pulsing bass. This could be considered one of the "quieter" mixes of the song, as it is not as aggressive as the other remixes.

===The Perfect Drug (The Orb)===

This remix begins with the lyric "You are the perfect drug" heavily distorted as a swirling beat comes in over it. The word "drug" is also repeated at various points in this version. At about three minutes in, the lyric "Take me with you" is repeated as the mix goes into a pseudo-breakdown. At the breakdown, a bass line over percussion, leads into the song's finale.

===The Perfect Drug (Aphrodite)===

This remix is exclusive to the vinyl edition of ''"The Perfect Drug" Versions.'' It's set in a different key than the other remixes and has a fast, electronic beat. As with most of the other remixes, it is light on lyrics, consisting only of "can't keep control/can't keep track," "taking me," and "you are perfect." A CD-quality MP3 file of the track was uploaded by Reznor on remix.nin.com.
