  • “The interaction found between sensation-seeking traits and the drug-taking experience show that predisposition to addiction has a genetic basis, and that this interacts with environmental factors such as patterns of drug use..
  • The sensation-seeking trait was predictive of rats’ likelihood to exhibit stronger motivation for drugs when we gave them the opportunity to take cocaine.”.
