Of the many defense mechanisms people use, denial, rationalization, and projection are commonly used and are the most pertinent to substance abuse. Denial is disavowing the existence of unpleasant realities. Rationalization is trying logically to justify irrational, socially, or personally unacceptable behaviors or feelings, and projection is attributing to another person one's unacceptable thoughts and feelings.
