Research focus
This article may help explain addiction science through research on methamphetamine, brain science, craving, relapse. The source abstract begins by describing: “Methamphetamine (METH) addiction involves escalating intake with strong cue reactivity, and high relapse risk, yet its neural mechanism remains unclear.”
Key finding: Specifically, the CLA → ACC circuit modulates intake, while reciprocal ACC → CLA circuit drive cue-induced relapse, revealing a maladaptive positive feedback loop that perpetuates METH addiction.
Why this may help: This may help explain why addiction can involve brain, behavior, mental health, craving, relapse, or treatment factors rather than simple willpower alone. It should be read as research information, not personal medical advice.
This article may help explain addiction science through research on cocaine, dopamine, brain science, craving. The source abstract begins by describing: “The authors show that rostral ventral pallidum projections to the ventral tegmental area (VTA) are activated during cue-induced reinstatement of cocaine seeking, and DREADD inhibition of these projections blocks this behavior.”
Key finding: This double dissociation in ventral pallidum subregional roles in drug seeking is likely to be important for understanding the mesocorticolimbic circuits underlying reward seeking and addiction.

This article may help explain addiction science through research on cocaine, methamphetamine, dopamine, brain science. The source abstract begins by describing: “Converging evidence indicates that both dopamine and glutamate neurotransmission within the nucleus accumbens (NAc) play a role in psychostimulant self-administration and relapse in rodent models.”
Key finding: These findings indicate that in contrast to the well-recognized mesoaccumbal dopamine system that is critical to psychostimulant reward and relapse, there is a parallel mesoaccumbal glutamatergic system that suppresses reward and psychostimulant-seeking behavior.

This article may help explain addiction science through research on opioid, alcohol, nicotine, brain science. The source abstract begins by describing: “Preclinical and human studies indicate psilocybin may reduce perseverant maladaptive behaviors, including nicotine and alcohol seeking.”
Key finding: We conclude that psilocybin reduces heroin relapse and highlight IL-17a signaling as a potential downstream pathway of psilocybin that also reduces heroin seeking.

This article may help explain addiction science through research on cannabis, brain science, withdrawal, craving. The source abstract begins by describing: “Cannabis withdrawal in cannabis use disorder (CUD) increase the risk of relapse and lacks effective treatments.”
Key finding: Increases in FAAH (%ΔFAAH whole-brain) were significantly associated with longer cannabis abstinence, greater baseline depression severity, and tendency to act without thinking ( p

This article may help explain addiction science through research on alcohol, cannabis, brain science, withdrawal. The source abstract begins by describing: “Alcohol use disorder (AUD) remains a pervasive public health issue with limited effective treatments.”
Key finding: These findings indicate that chronic CBD administration attenuates both behavioral and neurobiological facets of alcohol dependence by modulating neuronal excitability and preventing neurodegeneration, supporting its therapeutic potential for AUD and providing mechanistic insights for future research.
