Is it possible to cheat the iCup® drug screen by substituting or adulterating the specimen?

No. The iCup® A.D. contains a specimen validity test or SVT strip that verifies the validity of a specimen. The SVT strip checks for oxidants, specific gravity and pH in the specimen. For example, if someone tries to substitute water for urine, the specific gravity indicator will show an abnormal reading.
