Neurotransmitter orexin associated with pleasure and reward pathways in the brain
Researchers at the University of Pennsylvania School of Medicine have discovered that the recently identified neurotransmitter orexin (also known as hypocretin) influences reward processing by activating neurons in the lateral hypothalamus region of the brain. view more (2005-08-26)
Cocaine exposure during pregnancy leads to impulsivity in male, not female, monkeys
Adult male monkeys exposed to cocaine while in the womb have poor impulse control and may be more vulnerable to drug abuse than female monkeys, even a decade or more after the exposure, according to a new study by researchers at Wake Forest University School of Medicine. The findings could lead to a better understanding of human drug abuse. view more (2009-10-23)
Environmental enrichment can reduce cocaine use, researchers find
Simple environmental enrichment and increased social stress can both affect the level of individual drug use, according to new monkey research at Wake Forest University School of Medicine. view more (2008-04-07)
BUSM researchers find prenatal cocaine exposure may compromise neurocognitive development
Researchers at Boston University School of Medicine (BUSM) have found that heavier intrauterine cocaine exposure (IUCE) is associated with mild compromise on selective areas of neurocognitive development during middle childhood. view more (2009-05-01)
Stress-induced changes in brain circuitry linked to cocaine relapse
Stress-evoked changes in circuits that regulate serotonin in certain parts of the brain can precipitate a low mood and a relapse in cocaine-seeking, based on mouse studies published online this week in the Proceedings of the National Academy of Sciences. view more (2009-10-30)
Sugar can be addictive, Princeton scientist says
A Princeton University scientist will present new evidence today demonstrating that sugar can be an addictive substance, wielding its power over the brains of lab animals in a manner similar to many drugs of abuse. view more (2008-12-10)
Brain-behavior disconnect in cocaine addiction
Parts of the brain involved in monitoring behaviors and emotions show different levels of activity in cocaine users relative to non-drug users, even when both groups perform equally well on a psychological test. view more (2009-05-26)
Rutgers-Newark researchers link individual preferences to neuronal activity in brain
Based on research performed using laboratory rats, a team of neuroscience researchers at Rutgers University-Newark suggest that an intricate system exists within the brain for establishing individual preferences, which ultimately impacts choices. view more (2005-09-02)
New Treatment Option For Heroin Addiction (pp 634, 662)
An alternative drug therapy to methadone for the treatment of heroin addiction is proposed by Swedish authors of a study in this week's issue of THE LANCET. Methadone is an established treatment for heroin addiction-however it is usually only given to long-term addicts as there are concerns that it is addictive. Buprenorphine has been suggested... view more... (2003-02-19)
Drug commonly used for alcoholism, drug addiction, curbs urges of compulsive stealers
It appears that a drug commonly used to treat alcohol and drug addiction has a similar effect on the compulsive behavior of kleptomaniacs - it curbs their urge to steal, according to new research at the University of Minnesota. view more (2009-04-01)
The tachykinin receptor 3 gene has been linked to alcohol and cocaine dependence
The search for genes associated with alcohol dependence has recently been extended to the tachykinin receptor 3 gene, located within a broad region on chromosome 4q. Researchers have found that seven of the nine single nucleotide polymorphisms -- DNA sequence variations -- in the 3' region of TACR3 have a significant association with AD as well as... view more...

Evidence links cocaine abuse and Parkinson's disease
Adults who abuse cocaine might increase their risk of developing Parkinson's disease (PD), and pregnant women who abuse cocaine could increase the risk of their children developing PD later in life. view more (2005-12-13)
Studies find that 'broken heart syndrome' can result from opioid withdrawal, cocaine use
People who experience abrupt withdrawal from high-dose opioids or use cocaine increase their risk of cardiac event, according to two new studies published in the June issue of Mayo Clinic Proceedings. view more (2006-06-22)
A link is found between morphine addiction and the tendency to explore
A team of researchers from the UAB has found experimental evidence in rats showing a link between addiction to morphine and the tendency to explore perseveringly. view more (2006-02-21)
Prescription opioids the predominant choice among illicit opioid users
For almost a century, heroin addiction has been a core element of the illicit drug use problem in Canada. Recently, however, isolated reports have pointed to substantial increases in prescription opioid abuse. view more (2006-11-21)
Scientists design simple dipstick test for cocaine, other drugs
Researchers at the University of Illinois at Urbana-Champaign have developed a simple "dipstick" test for detecting cocaine and other drugs in saliva, urine or blood serum. view more (2006-11-14)
N.Y. Research Team Discovers How Antidepressants and Cocaine Interact with Brain Cell Targets
In a first, scientists from Weill Cornell Medical College and Columbia University Medical Center have described the specifics of how brain cells process antidepressant drugs, cocaine and amphetamines. These novel findings could prove useful in the development of more targeted medication therapies for a host of psychiatric diseases, most notably in... view more... (2008-07-30)
Screening for Attention Deficit-Hyperactivity Disorder (ADHD) among substance users is improved
Attention Deficit-Hyperactivity Disorder (ADHD) is a major learning disability among both children and adults. ADHD is especially common among drug users and alcoholics and increases the severity of their addiction problems. view more (2006-07-26)
