A hostile sociocultural environment is one of the risk factors for adolescents engaging in unhealthy behaviors, one of which is smoking. Smoking behavior is a growing problem that has not yet been solved in Indonesia. The implementation of various policies and strict regulations regarding cigarettes should reduce smoking behavior among adolescents, but the reality is not so and tends to be the opposite.
