Defining substance use disorders: do we really need more than heavy use?

AIMS: The aim of the study was to explore whether the concept of heavy substance use over time can be used as definition of substance use disorder. METHODS: Narrative review. RESULTS: Heavy use over time clearly underlies the neurobiological changes associated with current thinking of substance use disorders. In addition, there is evidence that heavy use over time can explain the majority of social problems and of burden of disease (morbidity and mortality). A definition of substance use disorders via heavy use over time would avoid some of the problems of current conceptualizations, for instance the cultural specificity of concepts such as loss of control. Finally, stressing the continuum of use may avoid the high level of stigmatization currently associated with substance use disorders. CONCLUSION: 'Heavy substance use over time' seems to be a definition of substance use disorders in line with results of basic research and epidemiology. Additionally, it reduces stigmatization. This approach should thus be further explored.

Commentary on the need for a research culture in the forensic sciences

Asked to comment on a collective discussion paper by Jennifer L. Mnookin et al., this Commentary identifies difficulties the authors encountered in defining or agreeing on the subject matter "forensic science" and its perceived deficiencies. They conclude that there is a need for a research culture, whereas this Commentary calls for the development of a forensic science culture through the development of forensic science education fed by research dedicated to forensic science issues. It is a call for a change of emphasis and, perhaps, of paradigm.

Methamphetamine Inhibitor: Calcium Nitrate– What You Need to Know, 2006

Iowa agriculture depends on anhydrous ammonia as a low-cost form of nitrogen fertilizer on 61 percent of Iowa’s 12.4 million acres of corn. Now we find a threat to that source of nutrient—the theft of anhydrous ammonia for use in making a powerful, illegal narcotic called methamphetamine. Naturally, the fertilizer industry is outraged by the illegal and illicit use of our products. We want to play a role in preventing abuse in the future. By raising awareness, knowing how to respond and using the Meth Inhibitor, fertilizer dealers can assist law enforcement in combating this illicit use of a product important to Iowa farmers.
