Colleagues point to a specific molecule in the brain that targets treatment to prevent relapses. Drugs are addictive because they "hijack" the brain's reward system. The "hijacking" is long-lived and often leads to relapses into abuse when the individual is exposed to. The part of the brain called , striatum, plays a major role in relapse.
