Research focus

This article may help explain addiction science through research on alcohol, brain science, withdrawal, mental health. The source abstract begins by describing: “Binge drinking is a significant problem in adolescent populations, and because of the reciprocal interactions between ethanol (EtOH) consumption and the endocannabinoid (eCB) system, we sought to determine if adolescent EtOH intake altered the localization…”

Key finding: These findings indicate that repeated exposure to EtOH during adolescence leads to long-term deficits in CB1 receptor expression, eCB-eLTD, and reduced recognition memory, but that these functional deficits can be restored by treatments that increase endogenous 2-arachidonoylglycerol.

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.

Cannabidiol mitigates alcohol dependence and withdrawal with neuroprotective effects in the basolateral amygdala and striatum

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.

Model of negative affect induced by withdrawal from acute and chronic morphine administration in male mice

This article may help explain addiction science through research on opioid, brain science, withdrawal, relapse. The source abstract begins by describing: “Opioid use disorder (OUD) is a chronic relapsing disorder that is a major burden for the lives of affected individuals, and society as a whole.”

Key finding: Altogether, these animal models will contribute to study behavioural and neuronal circuitries involved in the several negative affective signs characterizing OUD.

PET imaging of FAAH in chronic Cannabis users: longitudinal assessment during short-term abstinence

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

Acetazolamide inhibition of carbonic anhydrase 4 reverses opioid-induced synaptic rearrangements in nucleus accumbens and reduces drug-seeking behavior

This article may help explain addiction science through research on opioid, cocaine, brain science, withdrawal. The source abstract begins by describing: “Persistent vulnerability to drug-seeking is driven by enduring synaptic adaptations, yet current μ-opioid receptor-targeting pharmacotherapies provide limited efficacy against these neuroadaptations.”

Key finding: By targeting a pathway independent of classical opioid receptor signaling, CA4 inhibition represents a mechanistically distinct strategy that may reduce relapse vulnerability in OUD.

Microbial short-chain fatty acids regulate drug seeking and transcriptional control in a model of cocaine seeking

This article may help explain addiction science through research on cocaine, brain science, craving, relapse. The source abstract begins by describing: “Cocaine use disorder represents a public health crisis with no FDA-approved medications for its treatment.”

Key finding: These findings suggest that gut bacteria, via their metabolites, are key regulators of drug-seeking behaviors, positioning the microbiome as a potential translational research target.
