An addict will do whatever is necessary to maintain their addiction

An addict will do whatever is necessary to maintain their addiction. If they acknowledged the seriousness of the problem or the harm they’re causing themselves and others, they would be hard-pressed to continue this way of life. Their logic, whether conscious or unconscious, is: I need drugs, and I need lies to keep people off my back so I can continue using drugs. Thus, lying becomes a matter of self-preservation. Anything, or anyone, that is going to hinder their drug habit has no place in the addict’s life.
