Using the article by Adrian (2003), explain two of the major theories of addictions: 1) the structural-functional approach, and 2) the critical perspective. Provide TWO examples from the reading where each of these theories were applied in real life (e.g. Indigenous drug use in Canada). Finally, explain which theoretical approach (i.e. functionalism or conflict/critical theory) was used by Hari and which perspective was used by Nadelmann in their presentations. Please explain and justify your claim! (300+ words)
