Uncontrolled Substance is the debut solo album by American rapper and Wu-Tang Clan member Inspectah Deck. The album was released on October 5, 1999, under Loud Records. Originally slated for release in 1995, the record was postponed after a flood destroyed over 100 beats in RZA's basement, including his original productions for the album. Eventually released four years later, Uncontrolled Substance received mostly positive reviews, and is Inspectah Deck's most critically acclaimed and most commercially successful album to date. The album features Wu-Tang Clan members U-God and Masta Killa, and appearances from lesser-known affiliates Street Life, Killa Sin, and La the Darkman. A music video was made for the songs "Word on the Street" directed by Gregory Dark & "Show 'N' Prove" directed by Joseph Kahn. The album's liner notes state that it is dedicated to Inspectah Deck's late father, Frank Hunter.

Commercial performance

The album reached the positions no. 19 and no. 3 on the Billboard 200 and the Top R&B/Hip-Hop Albums charts, respectively. According to Inspectah Deck himself, the album managed to reach gold-level sales.
