She further goes on to state that the withdrawal symptoms may qualify as a DSM disorder in and of themselves and merit further medical and psychiatric concern. She does admit that coffee users who have no risk factors, such as cardiovascular problems, diabetes, etc. may be able to manage a comfortable addiction to the substance. Conclusion:

While the research is interesting and yelds some provocative information, there are several problems with this article, not the least is the trivializing of addiction and substance abuse by associating it with a morning cup of coffee. Nehlig agrees, "Thus, dependence and abuse should not be associated, and, as pointed out recently, discussing caffeine in terms of drugs of abuse might in fact trivialize the dangers of drugs such as cocaine."

Heightening it to the level of an opiate or other addiction is not only unnecessary but bad judgment in categorizing for disorder in the DSM.
