Ivory wave: the next mephedone? A new legal high has emerged that seems to be replacing the banned substance mephedrone or "miaow miaow", warns a critical care paramedic in Emergency Medicine Journal. Mephedrone was banned in England, when it was reclassified as a class B drug in April 2010. The new drug in circulation is "ivory wave," also known as "purple wave," "ivory coast," or "vanilla sky." And its use has already been implicated in hospital admissions and deaths in various parts of...

It seems that women become addicted to cocaine more easily than men and find it harder to give up. New research published in BioMed Central's open access journal Biology of Sex Differences reinforces this position by showing that the motivation of female rats to work for cocaine is much higher than males. Researchers from the Molecular and Behavioral Neuroscience Institute, University of Michigan, found that rats bred to have an elevated stress response and increased impulsiveness are more...

Air pollution is responsible for more heart attacks worldwide than cocaine, according to a new study published by Belgian researchers this week in the medical journal The Lancet. Scientists at Hasselt University and the Catholic University of Leuven claim that traffic fumes and dirty air trigger more than eight times as many heart attacks than the illicit drug, Telegraph Medical Correspondent Stephen Adams wrote on Thursday. Additionally, by looking at what they call "final straw" risk...

Archaeological evidence shows that South Americans were chewing coca leaves at least 8,000 years ago, an international team of researchers has discovered. The researchers, who were led by Dr. Tom Dillehay of the Vanderbilt University Department of Anthropology, discovered and dated coca leaves beneath house floors in the Nanchoc Valley of Peru. Dillehay and colleague describe their findings in a paper, which appears in the latest edition of Antiquity, a quarterly journal of archaeology...

For the first time, a therapeutic treatment has been shown to block the retrieval of memories associated with drug addiction Two separate discoveries by researchers at the University of Wisconsin-Milwaukee (UWM) offer potential for development of a first-ever pharmacological treatment for cocaine addiction. In one study, a common beta blocker, propranolol, currently used to treat hypertension and anxiety, has shown to be effective in preventing the brain from retrieving memories associated...

The water in the canals and irrigation channels in the L'Albufera Natural Park in Valencia contain cocaine, ecstasy and a further six drugs. This has been confirmed by a study carried out by researchers from the University of Valencia (UV), who have issued a warning about the continued presence of these substances on wildlife and human health. "The results confirm the presence of drugs such as cocaine, amphetamines, codeine, morphine and cannabis in the surface waters of the L'Albufera...

Now researchers at Linkoping University in Sweden and their colleagues can point to a specific molecule in the brain as a possible target for treatment to prevent relapses People who have used cocaine run a great risk of becoming addicted, even after long drug-free periods. Now researchers at Linköping University and their colleagues can point to a specific molecule in the brain as a possible target for treatment to prevent relapses. Drugs are addictive because they "hijack" the brain's...

Findings represent additional clues to help predict vulnerability to drug abuse A regulatory protein best known for its role in a rare genetic brain disorder also may play a critical role in cocaine addiction, according to a recent study in rats, funded by the National Institute on Drug Abuse (NIDA), a component of the National Institutes of Health. The study was published today in the journal Nature Neuroscience. Researchers at the Scripps Research Institute in Jupiter, Fla. found that...

Concordia University study evaluates role of drugs on sexual performance Sharing a bottle of red wine may seem like the best recipe for a romantic interlude. However, the evening may not turn out as planned according to a Concordia University study, which evaluated the effect of a wide range of drugs, including alcohol, on sexual behaviour. The findings, published in the journal Hormones and Behavior, definitively show that despite our preconceived notions, use of many recreational drugs can...

Cocaine toxicity due to drug overdose results in more than half a million emergency room visits annually. Despite these alarming statistics, there is no Food and Drug Administration-approved pharmacotherapy specifically designed to treat cocaine toxicity. Emergency medical personnel are limited to treating only the immediate life-threatening symptoms of patients, while toxic levels of cocaine and its metabolic break-down products persist and continue to damage the cardiovascular system, liver...
