Critical Kush https://cannabis-md.com/critical-kush-strain/ is an indica strain that delivers powerful, full-body relaxation and soothing mental effects. It is the brainchild of Barney's Farm, the Amsterdam-based growers who have given us such powerful strains as LSD and Liberty Haze. Critical Kush is a cross between Afghani-descended Critical Mass and none other than OG Kush.
