A study published in the Journal of Neuroscience by Texas A&M Health Science Center researchers found that a specific type of brain cell plays a crucial role in addiction. The findings suggest that periodic consumption of alcohol alters the structure and function of these cells, leading to increased cravings and cycle of alcoholism.
A Boston Medical Center model integrating nurse care managers into primary care increased physician waivers by 375% and patients' treatment access, particularly among African-American and Hispanic populations. The program has successfully treated over 8,000 Massachusetts patients with opioid dependence.
Researchers found that a single dose of cocaine interferes with recognizing negative emotions, such as sadness and anger. The study's lead author suggests this may explain why cocaine users report higher levels of sociability when intoxicated.
Researchers have discovered promising new compounds that may reduce alcoholics' urge to drink by targeting the brain's pleasure centers. The compounds, known as beta-carbolines, appear to be less addictive and cause fewer side effects than current treatments.
Research shows that long-term abstinent heroin users experience persistent brain dysfunction in the nucleus accumbens region. This altered activity may trigger intense cravings for drugs in response to stressors or environmental cues.

Heroin abuse has also expanded to groups not traditionally seen as widespread opiate users, highlighting the need for tailored treatment approaches.
Researchers at the University of Montreal found that how fast and how often drugs are taken contribute to addiction risk. Injection and smoking increase brain levels rapidly, leading to high cravings and compulsive behavior.
Researchers found that cortisol administration significantly reduced cravings for heroin in addicts, with a 25% decrease seen on average. The study suggests that cortisol may have inhibitory effects on addiction-related memory and behaviors.
Researchers found that e-cig liquids contain primarily free-base nicotine, the most addictive form, and often do not match label concentrations. This suggests that e-cigarettes can be just as hazardous to health as traditional tobacco products.
Researchers say combining educational messages about naloxone with sympathetic narratives can increase public support for its wider availability. The study found that people who heard humanizing stories of addiction were more likely to support policies for naloxone distribution.
A commentary in CMAJ argues that tamper-resistant opioids will not address the root causes of opioid addiction and overdose. Experts call for an evidence-based, multifaceted strategy to curb opioid-related harms.

A harm-reduction approach prioritizes minimizing harm from drug use for individuals and society, rather than solely focusing on punishment. This approach encompasses a range of objectives, including preventing overdose, treating addiction, and reducing the spread of diseases like HIV and hepatitis C.
Researchers found that e-cigarettes are less addictive than traditional cigarettes, with higher nicotine concentration and longer use leading to greater dependence. The study suggests that e-cigs may have health advantages over cigarettes due to lower levels of toxic substances.
A study of over 2,700 teens found that those prescribed anti-anxiety or sleep medications were 10-12 times more likely to abuse them than those who never received a prescription. The risk was higher for white, female, and long-term prescribers.
Researchers found that teens prescribed anxiety or sleep medications during their lifetime were 12 times more likely to misuse those drugs than those who had never been prescribed. The study also highlighted the risk of overdose when these medications are mixed with narcotics or alcohol.
Researchers found that memantine, an Alzheimer's drug, reduces binge eating by blocking addictive behaviors in the brain. The study identified the nucleus accumbens as a key area responsible for these behaviors, and applying memantine directly into this area suppressed binge-eating behavior.

Research suggests that effective interventions require a comprehensive approach addressing mental illness, substance abuse, trauma exposure, and social issues. New strategies aim to alleviate overrepresentation of individuals with serious mental health issues in the criminal justice system.
A new study found that a mother's harsh behavior towards her child at 2 years old is a strong predictor of problem behaviors in kindergarten. Maternal harshness can be influenced by drug use and affects parenting, leading to less emotional engagement with the child.
A recent study from Johns Hopkins Bloomberg School of Public Health found that people are more likely to have negative attitudes toward those suffering from drug addiction than those with mental illness. The researchers suggest that society often perceives substance abuse as a moral failing rather than a treatable medical condition.

A University of Cambridge study found that brain activity in people with compulsive sexual behavior is similar to that triggered by drugs in the brains of drug addicts. The ventral striatum, dorsal anterior cingulate, and amygdala regions were more active in individuals with compulsive sexual behavior compared to healthy volunteers.
A study by neuroscientists at Brigham Young University found that addiction starts with an overcorrection in the brain, triggering oxidative stress and a protein called BDNF. This process can lead to withdrawal symptoms like pain and anxiety.

Researchers discovered a new form of neurotransmission involving acid-sensitive ion channels (ASICs) that influence addiction-related behavior. Targeting ASIC activity may lead to new therapies for treating drug addiction.
Chronic UV radiation stimulates endorphin production, causing physical dependence and addiction-like behavior in mice. This finding could explain why people have an instinctive desire for sunlight despite its health risks. Researchers suggest that a conscious effort to limit sun exposure is needed to mitigate skin cancer risk.
Community opioid overdose prevention programs (OOPPs) have been shown to increase knowledge of overdose prevention and risk factors among bystanders. However, the effectiveness of these programs in reducing deaths from opioid overdose requires further investigation.
A new study has shed light on the role of dopamine-dependent reinforcement signals in the nucleus accumbens, a region connected to pleasure seeking and drug addiction. The research, using optogenetics, reveals how glutamate-dependent signals from other brain regions interact with these signals.
Practitioners can use shared decision making and motivational interviewing to adapt approaches for different clinical situations.

The study proposes that meditation can aid in cognitive recovery and provide additional benefits for individuals overcoming addiction.
A recent study found that random fluctuations in brain cell activity may influence our choices when faced with equal options. The research suggests that the orbitofrontal cortex plays a key role in decision-making and that neuronal signals can be biased by random noise, leading to close calls.
