Document Summary

The incenive salience theory focuses on how drug cues trigger excessive incenive moivaion for drugs, leading to compulsive drug seeking, taking, and relapse. The central idea is that addicive drugs alter nucleus accumbens circuits, making them hypersensiive to drug efects and drug-associated simuli. waning, in this context, refers to an acivaion of incenive- salience processes by drug-associated simuli. Drive theory: drugs elicit powerful posiive reinforcing efects that drive individuals to seek and use drugs. Congruent with intoxicaion stage of drug-addicion ccle where one uses a drug to achieve its intoxicaing and reinforcing efects. The acions of drugs on the bain"s reward circuitry explain the drug use at this stage (intoxicaion stage) Prior to addicion, when you take the drug, you"re body doesn"t counteract the efect (therefore you feel the efect) Ater addicion, your body starts to oppose the efects so you feel/funcion normally when your on it.
