Marijuana legalisation and pathological personality
The second question is the interesting one and it is not about the DSM. If no two personalities are alike, what makes one disordered — and the answer has to be something other than difference.

A policy question and a definitional one
Question one asks for a position on legalising possession of small amounts of marijuana, and then for unintended consequences, which is the part that distinguishes a thought-through answer. Take a position and support it, then work the consequences in both directions regardless of which side you took. Legalisation has produced documented effects that neither camp predicted precisely: changes in adolescent perception of risk, an increase in high-potency products, displacement rather than elimination of illicit markets where tax makes legal supply expensive, impaired-driving detection problems because no roadside test maps cleanly onto impairment, and expungement questions for people already convicted. Prohibition has its own unintended consequences, including the enforcement disparities that drove much of the reform argument. Naming consequences that cut against your own position is what makes the answer read as analysis rather than as advocacy, and the question asks for unintended consequences precisely because predicted objections are already on both sides of the public argument.
Question two is conceptually harder and is asking something philosophical rather than descriptive: if no two personalities are alike, what makes one pathological. The answer cannot be statistical rarity, since rare traits are often admired rather than treated. It cannot be social disapproval either, or diagnosis becomes a record of what a society will tolerate — and the history here is not reassuring, given what has previously been classified as disorder. The defensible answer rests on three things together: the traits are inflexible and pervasive across situations rather than context-appropriate; they are stable over time and traceable to adolescence or early adulthood; and they produce significant distress or functional impairment in work, relationships or self-direction. Impairment is the load-bearing criterion, and it is why a demanding, meticulous colleague is not thereby disordered. Say what the criteria exclude as well as what they capture, and acknowledge that the boundary remains contested — dimensional models exist because categorical thresholds are hard to defend.
Likely learning objectives
Inferred from the brief — check these against your own rubric.
- 01Take a policy position and identify consequences that cut against it.
- 02Distinguish unintended consequences from predicted objections.
- 03Explain why statistical rarity and social disapproval both fail as criteria for disorder.
- 04State the criteria that distinguish personality difference from personality disorder.

Review every instruction before using the planning guidance that follows.
Turn the brief into deliverables
- 01A supported position on marijuana legalisation.
- 02Unintended consequences, including ones unfavourable to your own position.
- 03A reasoned account of what makes a personality pathological.
- 04Recognition that the boundary is contested.
- 05APA-formatted citations.
Position, consequences, then the harder question
State the position
Answer the legalisation question directly with supporting reasoning.
Unintended consequences
Identify effects neither side predicted, on both sides of the argument.
Why rarity and disapproval fail
Rule out the two intuitive criteria and say why each fails.
The defensible criteria
Set out inflexibility, pervasiveness, stability and impairment together.
The contested boundary
Acknowledge dimensional models and the history of socially driven classification.
Sources for policy outcomes and diagnostic criteria
Recommended databases
- PubMed Central
- APA Dictionary of Psychology
- NCBI Bookshelf
- State health department cannabis programme evaluations
Search sequence
- 1.Look for published evaluations of states that legalised early, since those carry the observed rather than predicted effects.
- 2.Search specifically for outcomes that surprised researchers, which is what the unintended-consequences question wants.
- 3.Read the general diagnostic criteria for personality disorder rather than individual disorder criteria.
- 4.Find one source on the categorical-versus-dimensional debate, which is the honest ending for the second answer.
Reference shortlist
These are authoritative starting points, not a ready-made bibliography. A qualified reviewer must confirm that each source fits the assignment and supports the claim beside which it is cited.

Review before submission
Common mistakes
- Listing predicted objections and calling them unintended consequences.
- Answering the second question with a list of personality disorders instead of a criterion.
- Defining pathology as difference from the average, which the question rules out.
- Ignoring the history of socially driven diagnosis, which is the strongest challenge to any criterion.
- Treating distress and impairment as interchangeable when a person may have one without the other.
Submission checklist
- Is your position stated and supported?
- Do your unintended consequences include some that weaken your own case?
- Does your criterion for pathology exclude mere difference?
- Have you named inflexibility, pervasiveness, stability and impairment?
- Have you acknowledged that the boundary is contested?
