Substance use versus abuse and intoxication discussion
After reading the chapter and the Sam Spady case, discuss the difference between substance abuse and substance use, what substance intoxication is, whether the margarita drinker has a mental disorder, how using is distinguished from abusing, and which factors most explain substance abuse.

The diagnostic line, and where the example falls
The prompt's questions all circle one line, and naming it early makes the rest straightforward. Use is consumption. What current diagnostic systems recognise is substance use disorder, graded mild to severe, and it is defined by a pattern of impairment and distress across criteria such as loss of control, craving, failure to meet obligations, continued use despite harm, tolerance and withdrawal — not by quantity alone. The older term abuse described a pattern of harmful use that was diagnostically separate from dependence, and knowing that the two were merged into a single graded disorder is worth a sentence, because it explains why your textbook and a clinician may use different vocabulary for the same person. Then intoxication is a distinct concept again: a reversible, substance-specific syndrome of behavioural and physiological change occurring during or shortly after use. Name the manual you are working from, since the terms differ between editions.
The margarita question is testing exactly that distinction and it has a correct answer. Somebody who has two or three drinks after a long week and falls asleep on the couch has been intoxicated, and intoxication is not a mental disorder. Without impairment, loss of control or harm across time there is no disorder to diagnose, and the page reference the prompt gives is pointing at exactly this. The Sam Spady question needs care rather than confidence: her death involved acute alcohol poisoning after heavy drinking, and prevention arguments should rest on recognisable signs, willingness to call for help, and policies that remove the fear of calling — rather than on hindsight about individual choices. Finish with the multifactorial answer the last question wants, and give the evidence for the weighting you propose rather than asserting one factor. One cited statistic on campus drinking will carry that section further than a paragraph of concern.
Likely learning objectives
Inferred from the brief — check these against your own rubric.
- 01Define substance use disorder by criteria rather than by quantity consumed.
- 02Explain the shift from abuse and dependence to a single graded disorder.
- 03Distinguish intoxication from a substance use disorder.
- 04Apply diagnostic reasoning to an everyday drinking example.
- 05Weigh biological, personal, familial and social explanations against evidence.

Course-wide instructions that accompany this question
You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes. Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages. Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor. The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.

Review before submission
Common mistakes
- Defining abuse by the amount consumed rather than by consequences.
- Calling the margarita drinker disordered, which misreads the example.
- Using abuse and dependence as current diagnostic terms without noting the change.
- Confusing intoxication with withdrawal.
- Naming every possible causal factor without weighting any of them.
- Posting without a citation, which the prompt penalises by twenty points.
Submission checklist
- Substance use disorder is defined by criteria.
- The terminology change is acknowledged.
- Intoxication is defined as reversible and substance-specific.
- The margarita example receives a reasoned no.
- The causal answer weights factors and cites evidence.
- A citation and a matching reference appear in the initial post.
