What are the genetic and environmental factors in drug abuse?

Thank you.

Your response is very informative.

Genetic and environmental factors both significantly influence drug abuse.

Genetic Factors: Approximately 50% of an individual's risk for developing a substance use disorder is attributed to genetic predisposition. Specific genes related to dopamine regulation have been identified as contributing to addiction susceptibility, indicating a heritable component to drug abuse.

Environmental Factors: These include family dynamics, peer influences, socio-economic status, and exposure to drugs. Stressful life events and social environments can increase the likelihood of substance use, demonstrating the interplay between genetics and environmental context in the development of drug abuse behaviors.
