Document Summary
Addiction physically or psychologically dependent on a substance following use over a period of time. Physical dependence the body has adjusted to the substance and incorporates the use of that substance into the normal functioning. Tolerance the body increasingly adapts to the use of a substance, requiring larger and larger doses to obtain the same effects. Craving strong desire to engage in a behaviour or consume a substance; seems to result from a physical dependence and from a conditioning process. Withdrawal the unpleasant symptoms (both psychological and physical) that people experience when they stop using a substance on which they have become dependent, such as alcohol or tobacco. There is a difference in problem drinking versus alcoholism. Problem drinking involves more substantial social, psychological, and medical problems. Alcoholism was recognized as a disease in 1957. It is linked to high blood pressure, stroke, cirrhosis of the liver, cancer, fetal alcohol syndrome (fas), sleep disorders, and irreversible cognitive impairments.
