A fictional risk-decision card separating marketing claims, impairment, dependence, peer pressure and trusted support with a rehearsed safe exit.

Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.

What to include

  • Marketing claim/evidence screen.
  • Immediate impairment and support distinction.
  • Relative-risk correction.
  • Refusal with confirmed safe transport.
  • Urgent-help card and nonjudgmental support routes.

Review and revise

Use these criteria to check your work and choose what to improve.

  • Claim screen distinguishes relative-risk claims from unsupported zero-risk advertising.
  • Case analysis separates impairment, dependence concerns and urgent warning signs.
  • Refusal/transport plan names a confirmed non-impaired option and safe waiting arrangement.
  • Support record distinguishes qualified routine help from emergency action without diagnosing or stigmatizing.

The idea in everyday life

Supplied educational facts: vaping aerosol may contain nicotine and other harmful substances; some adults who smoke may reduce certain harms by completely switching under qualified guidance, but youth should not vape. Fictional seller says fewer smoke chemicals means safe for a 16-year-old.

The idea

Less of one hazard does not mean no hazard.

Follow along

Compare product claims without assuming safety — supplied practice

Less of one hazard does not mean no hazard.

Supplied educational facts: vaping aerosol may contain nicotine and other harmful substances; some adults who smoke may reduce certain harms by completely switching under qualified guidance, but youth should not vape. Fictional seller says fewer smoke chemicals means safe for a 16-year-old.

  1. 1. Step 1

    Record the seller’s leap from fewer to safe.

    You should see: The claim converts a relative comparison into a zero-risk conclusion.

  2. 2. Step 2

    Apply the age/context difference.

    You should see: Adult smoking contexts do not establish suitability for youth.

  3. 3. Step 3

    Keep ingredient uncertainty and dependence risk visible.

    You should see: Aerosol and nicotine concerns remain relevant.

  4. 4. Step 4

    Draft a correction without recommending a product.

    You should see: The comparison does not make vaping safe for youth; seek official information and qualified cessation support if needed.

Now change one thing

The seller adds a candy flavor. Enter removes or retains for the risk concerns.

Your work

What to finish

A relative-risk correction card.

Common mistake

Watch for this

No product use or cessation medication decision is made here.

How can I tell I understand it?

Support each lesson-specific criterion with your supplied-case artifact: I identified the relative-to-absolute leap.; I preserved age and context differences.; I avoided recommending a substance product.
