PET imaging studies reveal how an inoculation against cocaine addiction uses the body's own immune system to prevent a high Addicts unable to kick a cocaine habit could one day be vaccinated against cocaine and see proof with a molecular imaging technique that shows how the vaccine prompts antibodies to whisk away the drug before it can reach the brain, say researchers at SNM's 59th Annual Meeting. "Vaccination offers a whole new treatment paradigm for drug addiction," says Shankar...

The discovery of the first enzyme in the pathway sheds new light on the evolution of alkaloid formation Humans encounter alkaloids every day Alkaloids constitute a very large group of natural nitrogen-containing compounds with diverse effects on the human organism. A large variety of plant-produced alkaloids have strong pharmacological effects, and are used as toxins, stimulants, pharmaceuticals or recreational drugs, including caffeine, nicotine, morphine, quinine, strychnine, atropine...

'Horror Stories' Surfacing of Deadly Columbian Mind-Control Drug

Experts are warning about a dangerous drug currently being dealt in Colombia that can reportedly rob an individual of their free will, making them vulnerable to criminals and attackers, or erase their memories. The drug is known as scopolamine, and according to Gizmodo reporter Sam Biddle, the substance, which is derived from plants like cocaine, "will turn you into an insane zombie and probably kill you." Scopolamine, otherwise known as "The Devil's Breath," was tested by the CIA as a...

Chronic Cocaine Use Triggers Changes In Brain's Neuron Structure
2012-05-09 14:26:44

Chronic exposure to cocaine reduces the expression of a protein known to regulate brain plasticity, according to new, in vivo research on the molecular basis of cocaine addiction. That reduction drives structural changes in the brain, which produce greater sensitivity to the rewarding effects of cocaine. The finding suggests a potential new target for development of a treatment for cocaine addiction. It was published last month in Nature Neuroscience by researchers at the University at...

(Ivanhoe Newswire)-- The United Nations Office on Drugs and Crime estimates that cocaine is used by up to 21 million individuals worldwide, with approximately 1 per cent of these individuals becoming dependent. Now, a new study shows that frequent cocaine abuse can lead to accelerated aging of the brain. Cocaine is a strong central nervous system stimulant that increases levels of dopamine, a brain chemical associated with pleasure and movement, in the brain´s reward circuit. The...

A history of binge eating -- consuming large amounts of food in a short period of time -- may make an individual more likely to show other addiction-like behaviors, including substance abuse, according to Penn State College of Medicine researchers. In the short term, this finding may shed light on the factors that promote substance abuse, addiction, and relapse. In the long term, may help clinicians treat individuals suffering from this devastating disease. "Drug addiction persists as a...

Research shows chronic users' brains age dramatically faster than their non-drug-using peers New research by scientists at the University of Cambridge suggests that chronic cocaine abuse accelerates the process of brain aging. The study, published today 25 April in Molecular Psychiatry, found that age-related loss of grey matter in the brain is greater in people who are dependent on cocaine than in the healthy population. For the study, the researchers scanned the brains of 120 people...

New research from Mount Sinai Medical Center in New York reveals that repeated exposure to cocaine decreases the activity of a protein necessary for normal functioning of the brain's reward system, thus enhancing the reward for cocaine use, which leads to addiction. Investigators were also able to block the ability of repeated cocaine exposure, to induce addiction. The findings, published online April 22 in the journal Nature Neuroscience, provide the first evidence of how cocaine changes the...
