Cocaine Use Related to Level of Education Achieved
The decreased use of cocaine in the United States over the last 20 years mostly occurred among the highly educated, while cocaine use among non-high school graduates remained constant, according to a study by researchers at the Johns Hopkins Bloomberg School of Public Health.   view more (2007-08-30)

Cicardian system suffers and protects from prenatal cocaine exposure
Researchers from Boston University School of Medicine (BUSM) have shown that prenatal cocaine exposure in zebrafish (which share the majority of the same genes with humans) can alter neuronal development and acutely dysregulate the expression of circadian genes and those affecting melatonin... view more (2007-07-11)

Recreational cocaine use may impair inhibitory control
The recreational use of cocaine has rapidly increased in many European countries over the past few years.   view more (2007-11-07)

Comparison of cocaine and methamphetamine 'highs' finds differences in onset, pattern and duration
Investigators at the Jane and Terry Semel Institute for Neuroscience and Human Behavior at UCLA examining responses to cocaine and methamphetamine use find distinct differences in onset, pattern and duration.   view more (2005-08-25)

Research reveals molecular fingerprint of cocaine addiction
The first large-scale analysis of proteins in the brains of monkeys addicted to cocaine reveals new information on how long-term cocaine use changes the amount and activity of various proteins affecting brain function.   view more (2008-05-28)

Delving deeper into the machinery of cocaine addiction
Researchers are now understanding in greater detail the molecular machinery underlying the short-term brain changes that produce the high of cocaine, as well as the longer-term changes behind addiction. Their findings offer hope for targeted drugs that can short-circuit that addiction machinery.   view more (2005-10-20)

Animal research suggests new strategy for treating cocaine addiction
New research in monkeys suggests the feasibility of treating cocaine addiction with a "replacement" drug that mimics the effects of cocaine but has less potential for abuse - similar to the way nicotine and heroin addictions are treated.   view more (2008-04-07)

Strokes may be associated with cocaine and amphetamine abuse
The use of stimulant drugs, including cocaine and amphetamines, may be linked to a higher risk for stroke, according to a report in the April issue of Archives of General Psychiatry, one of the JAMA/Archives journals.   view more (2007-04-03)

New treatment effective in counteracting cocaine-induced symptoms
UT Southwestern Medical Center researchers have discovered a treatment that counteracts the effects of cocaine on the human cardiovascular system, including lowering the elevated heart rate and blood pressure often found in cocaine users.   view more (2007-08-13)

PET imaging confirms link between receptor levels and cocaine abuse
Using positron emission tomography (PET), researchers have established a firm connection between a particular brain chemistry trait and the tendency of an individual to abuse cocaine and possibly become addicted, suggesting potential treatment options.   view more (2006-07-12)

New study finds common herbal supplement helps to reduce cocaine cravings
A new study funded by the National Institutes of Health (NIH) suggests that a common over-the-counter herbal supplement can reduce the cravings associated with chronic cocaine use.   view more (2005-12-14)

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)

High-tech research shows cocaine changes proteins and brain function
In the first large-scale analysis of proteins in the brains of individuals addicted to cocaine, researchers have uncovered novel proteins and mechanisms that may one day lead to new treatment options to fight addiction.   view more (2006-11-01)

New data hint at oncoming cocaine epidemic
Like some drug déjà vu, cocaine use is once again on the rise among students and the rich and famous, a trend University of Florida researchers say likely signals a recurring epidemic of abuse.   view more (2006-10-18)

Prenatal cocaine exposure not linked to bad behavior in kids
oddlers exposed to cocaine before birth exhibit no more behavioral problems than other children their age, despite early predictions that "crack babies" would grow up to be delinquents.   view more (2006-05-02)

Cocaine's effects on brain metabolism may contribute to abuse
Many studies on cocaine addiction - and attempts to block its addictiveness - have focused on dopamine transporters, proteins that reabsorb the brain's "reward" chemical once its signal is sent.   view more (2008-02-19)

Researchers identify key step in cocaine-induced heart enlargement, sudden death
Cocaine, in concentrations commonly sold on the street, causes the abnormal buildup of primitive proteins in heart muscle - a process causing heart enlargement that can ultimately lead to sudden death.   view more (2006-09-08)

Young people are intentionally taking drink and drugs for better sex
Teenagers and young adults across Europe drink and take drugs as part of deliberate sexual strategies. Findings published today in BioMed Central's open access journal, BMC Public Health, reveal that a third of 16-35 year old males and a quarter of females surveyed are drinking alcohol to increase... view more (2008-05-09)

Prenatal cocaine's lasting cellular effects
Although the "crack baby" hysteria of the 1980s was greatly exaggerated, cocaine use during pregnancy can cause subtle but disabling cognitive impairments — attention deficits, learning disabilities and emotional problems.   view more (2007-01-15)

Cocaine-induced synaptic plasticity linked to persistent addictive behaviors
The persistent nature of addiction is its most devastating feature. Understanding the mechanism underlying this phenomenon is the key for designing efficient therapy. Two separate studies published by Cell Press is the August 14 issue of the journal Neuron identify specific cocaine-induced changes... view more (2008-08-14)

High resolution 'snapshots' detail dynamics of a cocaine antibody
Cocaine-binding antibodies have shown some promise in their ability to neutralize cocaine toxicity, but their binding ability is severely impaired by high concentrations of the drug.   view more (2006-02-09)

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)

UT Southwestern researchers find alterations in brain's circuitry caused by cocaine
Cocaine causes specific alterations in the brain's circuitry at a genetic level, including short-term changes that result in a high from the cocaine, as well as long-term changes seen in addiction.   view more (2005-10-24)

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)

Gene controlling circadian rhythms linked to drug addiction, UT Southwestern researchers find
The gene that regulates the body's main biological clocks also may play a pivotal role in drug addiction, researchers at UT Southwestern Medical Center have found.   view more (2005-06-14)
