In my studies of addiction, the concept of cravings comes up often. Researchers talk of wanting versus liking of drugs and of the idea that cravings are a programmed response to environmental signals that have been connected to drug use through experience.
Drug craving and the other compulsive behaviors are the essence of addiction. They are extremely difficult to control, much more difficult than any physical dependence. They are the principal target symptoms for most drug treatment programs. For an addict, there is no motivation more powerful than drug craving.
