Which factor is known to influence addiction significantly during adolescence?

The peer and school environment is a major influence on addiction during adolescence due to the unique developmental stage that this age group is undergoing. Adolescents are particularly susceptible to social influences, making them more likely to engage in risky behaviors, such as substance use, based on their interactions with peers.

During this period, young individuals often prioritize peer acceptance and are heavily impacted by their friends' behaviors, attitudes, and expectations regarding substance use. For instance, if an adolescent is surrounded by peers who endorse or engage in drug or alcohol use, the likelihood of them experimenting with these substances increases significantly. Additionally, the school environment can also play a role; schools that provide supportive services, positive peer interactions, and effective interventions can help mitigate these risks.

While genetic predisposition can play a crucial role in addiction susceptibility, its influence can be exacerbated or mitigated by environmental factors like peer relationships and school climate. Family income level and access to rehabilitation services, while important in terms of overall health and resource availability, do not directly influence the decision-making process and risk behavior as prevalently as peer and school environments do during adolescence.
