Drug effects in context

Where the drug fits

Where to look: The drug is represented by the substance, medicine or metaphor in this reference; this is not a picture of its molecular target.
How it interacts: After entering the body, a drug can reach proteins such as receptors, transporters or enzymes. Its visible form does not tell you which protein it affects.
What changes: Connect the example to exposure and target action; do not infer a mechanism from appearance alone.

What to understand

These references introduce the course's central distinction: a chemical's effects depend on its targets, delivery, individual biology and social setting. A photograph or metaphor can introduce that idea, but cannot establish a mechanism or a treatment's effectiveness.

About these source images

Graphics extracted from the seven supplied professor decks and Julien Chapters 1–4 captures. Original labels and source wording are preserved; the adjacent drug examples are study commentary. Repeated artwork is retained where its teaching context differs. Multiple-choice practice provides feedback and does not award mastery or XP.

The Julien file contains incomplete and loading captures. Split figures appear as sequential panels; missing material is not reconstructed. Small labels may remain limited by the original capture. Historical clinical and policy references are not current treatment or legal guidance.
