Research focus
This article may help explain addiction science through research on alcohol, brain science, genetics. The source abstract begins by describing: “Increases in impulsivity and negative affect (e.g., neuroticism) are common during adolescence and are both associated with risk for alcohol-use initiation and other risk behaviors.”
Key finding: Consistent with current equifinality-based conceptions of development, few connections predicted both impulsivity and neuroticism, indicating that the neural signatures of these two traits are relatively distinct despite both being implicated in alcohol-use risk and a wide array of behaviors.
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 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.

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 opioid, alcohol, dopamine, brain science. The source abstract begins by describing: “It is well documented that ethanol exposure alters GABA (γ-aminobutyric acid)-releasing synapses, and ethanol addiction is associated with endogenous opioid system.”
Key finding: These neuroadaptations to ethanol might contribute to early stage of addiction.

This article may help explain addiction science through research on opioid, alcohol, cannabis, nicotine. The source abstract begins by describing: “Substance use disorders (SUDs, including alcohol, cannabis, opioids, and tobacco) represent significant public health challenges.”
Key finding: Lastly, using a real-world dataset, we identified seven SUD-shared genes targeting drugs that may be repurposed for treating SUDs, particularly in those suffering from comorbid SUDs.

This article may help explain addiction science through research on opioid, alcohol, cocaine, methamphetamine. The source abstract begins by describing: “Substance use disorders (SUDs) are common and costly conditions that are partially attributable to genetic factors.”
Key finding: Overall, the findings highlight similarities and differences in immunogenetic profiles of SUDs that may influence the prevalence and co-occurrence of problematic SUDs and may contribute to assessment of SUD risk of an individual on the basis of their HLA genetic makeup.
