Step-by-step explanation:
Howard S. Becker's model of drug use holds that drug use is primarily shaped by the user subculture.
According to Becker, drug use is influenced by the norms, values, and practices of a particular group or subculture to which the individual belongs. This subculture provides the social context and support for drug use, shaping an individual's attitudes and behaviors towards drug use.
Becker's model emphasizes the sociocultural factors that influence drug use, rather than genetic factors, peer pressure, or random choice.
