Which explanation for the progression from marijuana use to the use of more dangerous drugs focuses on properties inherent within the drug?

• A. Sociocultural School
• B. Predisposition School
• C. Selective Interaction/Socialization School
• D. Pharmacological School

Answer: (D)

The key idea is that the drug’s own properties can shape what a user does next. From the pharmacological standpoint, the effects, potency, onset, and the brain changes produced by marijuana itself can influence a person’s drug-taking trajectory. Its pharmacology can reinforce use, create tolerance, or alter reward pathways in a way that makes other substances seem more appealing or necessary to achieve desired effects or counteract withdrawal. In short, the drug’s inherent characteristics—the way it acts on the brain and body—are seen as a driving force behind moving to stronger or different drugs. Other explanations focus on the social environment, individual predispositions, or peer influences rather than the drug’s own biology.
