Addiction Versus Abuse
People often confuse substance abuse with substance addiction, and even though there is a difference, sometimes it can be hard to tell.
Substance abuse is the use of any substance in a manner for which it is not intended and/or amounts which are excessive and chronic. Examples include drinking to "Feel" good, or using a prescribed medication to get a little "High". However, in the case of abuse, the person understands there is a problem and can stop using.
Addiction implies a more severe form of substance abuse. Addiction typically manifests with accompanying brain disease or damage called “dependence”. The symptoms of addiction can be either physical or mental and are usually a combination of both.
Addiction usually starts with with abuse and progresses from there, evolving into a physical and mental dependence.
