New Mount Sinai research tracks effects of addictive drugs on brain
Mount Sinai researchers may have unlocked the key to better understanding the effect addictive drugs have on the human brain.   view more (2008-05-16)

Nicotinic receptors may be important targets for treatment of multiple addictions
For years, scientists have known that some people are biologically more susceptible to drug addiction than others, but they have only been able to speculate why.   view more (2007-08-16)

Research reveals why some smokers become addicted with their first cigarette
New research from The University of Western Ontario reveals how the brain processes the 'rewarding' and addictive properties of nicotine, providing a better understanding of why some people seemingly become hooked with their first smoke.   view more (2008-08-06)

New study finds anabolic steroids may be addictive
A new study designed to test whether androgenic-anabolic steroids may be addictive found that hamsters exposed to the compounds demonstrated addictive behavior over time.   view more (2005-12-14)

Assembling the jigsaw puzzle of drug addiction
Using an integrative meta-analysis approach, researchers from the Center for Bioinformatics at Peking University in Beijing have assembled the most comprehensive gene atlas underlying drug addiction and identified five molecular pathways common to four different addictive drugs.   view more (2008-01-07)

Landmark Carnegie Mellon Addiction Study Finds People Underestimate Power of Drug Cravings
A novel experiment conducted by Carnegie Mellon University Professor George Loewenstein and colleagues may explain why people try a drug, such as heroin, for the first time despite ample evidence that it is addictive.   view more (2007-02-13)

Singing to females makes male birds' brains happy
The melodious singing of birds has been long appreciated by humans, and has often been thought to reflect a particularly positive emotional state of the singer.   view more (2008-10-03)

Gene therapy reduces cocaine use in rats
Researchers at the U.S. Department of Energy's Brookhaven National Laboratory have shown that increasing the brain level of receptors for dopamine, a pleasure-related chemical, can reduce use of cocaine by 75 percent in rats trained to self-administer it.   view more (2008-04-16)

Antipsychotic drug may block addiction, UIC researchers find
Researchers at the University of Illinois at Chicago have discovered that a long-approved oral antipsychotic drug can stop the addictive properties of opioid painkillers in mice.   view more (2006-02-09)

Cocaine: How addiction develops
Permanent drug seeking and relapse after renewed drug administration are typical behavioral patterns of addiction. Molecular changes at the connection points in the brain's reward center are directly responsible for this.   view more (2008-08-22)

Tobacco companies engineer high addiction cigarettes with additives
Tobacco companies have added chemicals to cigarettes to increase the addictiveness of nicotine and keep smokers hooked. A new joint report by ASH, Imperial Cancer Research Fund and the US State of Massachusetts reveals over sixty tobacco industry documents dealing with the use of additives in... view more (1999-07-14)

Blunt smokers link dependence potential to nicotine
According to a study by researchers at National Development and Research Institutes, Inc. (NDRI) users of blunts (tobacco cigar shells filled with marijuana) do not understand or experience marijuana dependence in terms of conventional clinical criteria.   view more (2006-09-27)

Research offers new approach to developing treatments for cocaine and amphetamine addiction
The study shows that highly addictive drugs, like cocaine and amphetamine, require a neurotransmitter called CART (Cocaine- and Amphetamine-Regulated Transcript) peptides to produce their maximal effects.   view more (2005-09-29)

K-State professor's research suggests that cigarettes' power may not be in nicotine itself
There may be a very good reason why coffee and cigarettes often seem to go hand in hand.   view more (2008-09-04)

Study reveals how ADHD drugs work in brain
Although millions depend on medications such as Ritalin to quell symptoms of attention deficit hyperactivity disorder (ADHD), scientists have struggled to pinpoint how the drugs work in the brain.   view more (2006-06-26)

New study demonstrates nicotine's role in smoking behavior
Tobacco dependence is the leading cause of mortality in Canada. Although most smokers express a desire to stop smoking, only a small number are able to succeed. A new study from the Centre for Addiction and Mental Health (CAMH, Canada) and the National Institutes of Health (NIH, USA) reveals that... view more (2007-02-28)

Study examines substance abuse prevalence among teens receiving routine medical care
Approximately 15 percent of teens receiving routine outpatient medical care in a New England primary care network had positive results on a substance abuse screening test.   view more (2007-11-06)

Nature or Nurture-Are You Who Your Brain Chemistry Says You Are?
Researchers using positron emission tomography (PET) have validated a long-held theory that individual personality traits-particularly reward dependency-are connected to brain chemistry, a finding that has implications for better understanding and treating substance abuse and other addictive... view more (2008-08-13)

Mechanism of nicotine's learning effects explored
While nicotine is highly addictive, researchers have also shown the drug to enhance learning and memory—a property that has launched efforts to develop nicotine-like drugs to treat cognitive deficits in Alzheimer's and Parkinson's diseases, schizophrenia, and attention-deficit/hyperactivity... view more (2007-04-05)

Initial reaction to nicotine can dictate addiction
Following up on studies that have indicated the speed with which adolescents can get hooked on cigarettes, researchers at the University of Massachusetts Medical School have conducted the first study to determine why some adolescents who try smoking get addicted while others do not.   view more (2007-10-01)

How does the opioid system control pain, reward and addictive behavior?
The opioid system controls pain, reward and addictive behaviors. Opioids exert their pharmacological actions through three opioid receptors, mu, delta and kappa whose genes have been cloned (Oprm, Oprd1 and Oprk1, respectively).   view more (2007-10-15)

Abuse of painkillers can predispose adolescents to lifelong addiction
No child aspires to a lifetime of addiction. But their brains might. In new research to appear online in the journal Neuropsychopharmacology this week, Rockefeller University researchers reveal that adolescent brains exposed to the painkiller Oxycontin can sustain lifelong and permanent changes in... view more (2008-09-10)

Attitudes to Cannabis are More Tolerant
People are becoming more tolerant of the use of cannabis, but there are still clear limits to what is acceptable in the area of illegal drug-taking, according to new research funded by the ESRC.
