Research focus
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.
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 opioid, alcohol, cannabis, nicotine. The source abstract begins by describing: “Despite the benefits associated with longer buprenorphine treatment duration (i.e., >180 days) (BTD) for opioid use disorder (OUD), retention remains poor.”
Key finding: Longer BTD is associated with diagnoses of psychiatric and somatic conditions in the EHR, as is the genetic score for OUD, loneliness, problematic alcohol use, and externalizing disorders.

This article may help explain addiction science through research on alcohol, cannabis, nicotine, dopamine. The source abstract begins by describing: “In this Opinion article, Nutt and colleagues examine the history of and current evidence for the dopamine theory of addiction.”
Key finding: These observations have implications for understanding reward and treatment responses in various addictions.

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.
