Genetic factors contribute to what proportion of the risk for addiction?

Less than one-tenth
One-quarter
One-half
Three-quarters

The correct answer is: One-half

Genetic factors are understood to play a significant role in the risk for addiction, contributing to about half of the overall risk. This figure is supported by numerous studies indicating that genetics can influence an individual's susceptibility to developing addictive behaviors, alongside environmental and socio-economic factors. The complexity of addiction means it often results from a combination of multiple influences, but estimates suggest that genetic predisposition accounts for approximately 40% to 60% of the risk, with many studies tending towards the higher end of this range. This understanding helps in formulating preventive measures and treatment approaches that consider both genetic and environmental factors, underscoring the multifactorial nature of addiction. In contrast, the other options underrepresent the genetic contribution to addiction risk, as none suggest a proportion that accurately reflects the established research on the influence of genetics in this area.
