"[3] Centered on release and freedoms from inhibiting addictions and habits, Rehab is a highly conceptual album.

[9] Originally thought to be the first single of Rehab, Lecrae stated that it is a theme song for a Christian camp called Kanakuk Kamps.

[10] A video was posted via Rapzilla on August 19, 2010 of Lecrae rapping a verse from the song "Walking on Water".

[11] According to Lecrae's blog, he will be in Southern Sudan at the time of the album's release so the "distractions of my life are stripped away and I'm left to focus on Jesus and his mission."

Rapzilla's Logan Remy gave Rehab a 4.5/5 rating, calling it "Lecrae's best project to date".

Michael Weaver of Jesus Freak Hideout rated the album 5/5 stars, expressing high acclaim for it.

Rapzilla reported that the debut week sales for Rehab were 25,864 units, about 15,000 more than Lecrae's previous album, Rebel.

[21] HipHopDX reported this figure at approximately 28,000 units, ahead of Ice Cube's I Am the West which was released on the same day.
