In mid-2005, Sauron announced his withdrawal from Decapitated, stating: "It was not an easy decision.
However, I could reconcile the welfare of the band with my personal plans, and hence quitting appeared to be the best solution not hampering the evolution of Decapitated.(...)
Moreover, another reason that contributed to my decision have been some health complications."
The band chose Adrian "Covan" Kowanek, a previous member of Atrophia Red Sun, as his replacement and entered Hertz Studios in Białystok in August to record their ambitious fourth album Organic Hallucinosis, which was released the following February.
According to Allmusic, the band's musical change of direction on this album was "likely to polarize longtime Decapitated fans".

During the following tour in December 2005, Martin could not perform with the band due to military conscription issues and was shortly substituted by Richard Gulczynski, but joined again in February 2006.
During the year, Decapitated toured with American bands Suffocation, Six Feet Under, Fear Factory, and others.
In June and July 2007, Decapitated played with Cephalic Carnage and others in the Summer Slaughter trek across the US.
Once the tour ended, Martin departed from Decapitated to live with his family and to move to California.

On October 28, 2007, the remaining three band members were involved in an automobile accident that injured Vitek and Covan.
Their tour bus collided with a truck carrying wood in Gomel, near the border from Russia to Belarus.
Vitek died on November 2, 2007 at the age of 23 in a Russian hospital from the injuries.
Covan slipped into a coma and was later moved to Poland.
In 2008, Metal Mind Productions released the concert DVD Human's Dust.
