Meaning of craving in research on addiction

The meaning of the word craving varies as illustrated by Kozlowski and Wilkinson's reports of ambiguities in use amongst cigarette smokers. We extended this line of investigation to problem drinkers who sought a goal of controlled drinking versus abstinence, to professionals involved in the addictions area, and to university students. Significant differences in meaning were noted particularly among the problem drinkers (N = 256 between 17 and 60 years of age). Reasons for this are offered.
