What is drug “craving”?
Drug craving is an urge or desire to continue taking the drug. In the drug research arena, the word “craving” does not have a solid scientific meaning. It is also difficult to measure. When patients are asked to describe drug craving, scientists receive widely different answers. Thus, the words “urge” or “desire” are often more meaningful. Craving is not the same as drug dependence (“addiction”).
