I’m working on a health & medical question and need guidance to help me learn.

The Stauffer et al. article and Glidden-Tracey article introduce several terms used when assessing substance use. Additionally, the DSM 5 differentiates among severity levels of substance use compared to the old diagnoses of abuse/dependence. Currently, you need to be able to be familiar with these terms describing substance use as well as the assessment process. What are the differences among abuse, dependence, mild/moderate/severe use, harmful/hazardous use and social use as you see it, and what do you think the implications are for treatment? Do you think clients can socially use one substance and be dependent on or abuse another? What is your evidence for your opinion?
