People with an addiction do not have control over what they are doing, taking or using. Their addiction may reach a point at which it is harmful. Addictions do not only include physical things we consume, such as drugs or alcohol, but may include virtually anything, such abstract things as gambling to seemingly harmless products, such as chocolate - in other words, addiction may refer to a substance dependence (e.g. drug addiction) or behavioral addiction (e.g. gambling addiction).

Addiction / substance abuse is a complex of brain disease, evidences strongly suggests that genetic susceptibilities and biological traits play a vital role in addiction, but it is also developed and shaped by a person’s environment.

Addiction is a term of long-standing and variable usage. It is regarded by many as a discrete disease entity, a debilitating disorder rooted in the pharmacological effects of the drug, which is remorselessly progressive.
