Crystal methamphetamine use increases HIV risk
The use of crystal methamphetamine by men who have sex with men (MSM) increases the risk of HIV transmission and can cause complications in those who are already HIV-positive, according to an article in the March 15 issue of Clinical Infectious Diseases, now available online. (2004-03-02)

Methamphetamine withdrawal associated with brain changes seen in mood disorders
Results of a new study indicate that people who have recently stopped abusing the powerfully addictive drug methamphetamine may have brain abnormalities similar to those seen in people with mood disorders. The findings suggest practitioners could improve success rates for methamphetamine users receiving addiction treatment by also providing therapy for depression and anxiety in appropriate individuals.

Study finds lobeline reduces self-administration of methamphetamine in rats
Lobeline, a drug with a long history of use in smoking cessation programs, may be a potential treatment for methamphetamine abuse. In a previous study using rats, researchers from the University of Kentucky found that lobeline decreased the animals' self-administration of d-methamphetamine (METH). They concluded that lobeline acted by decreasing the animal's perception of METH- induced pleasure (reward). (2003-05-02)

Study of twins reveals changes in attention and motor skills after heavy stimulant abuse
In a study supported by the National Institute on Drug Abuse (NIDA), researchers studied 50 pairs of twins; in each pair, one twin had a history of abusing cocaine and/or methamphetamine and the other had no history of drug abuse. They found that the twin with a history of stimulant abuse performed significantly worse on several tests of attention and motor skills than did the sibling who had never used drugs. (2003-04-09)

Research on lentiviruses to continue at Ohio State
A major research project which found that methamphetamine greatly speeds a virus' ability to infect neural cells will continue at Ohio State University. Researchers hope the ongoing work will identify the factors responsible for enhancing the viruses' infection of the nervous system. The university and the National Institute on Drug Abuse today announced the continuation of the five-year, $1.63 million project begun nearly two years ago. (2002-10-29)

NIDA experts to discuss drug abuse, treatment, and prevention at APA Convention in Chicago
At this year's American Psychological Association (APA) convention being held in Chicago from August 22-25, 2002, National Institute on Drug Abuse (NIDA) Acting Director, Dr. Glen R. Hanson will discuss the critical role of psychology and behavioral science in understanding various aspects of drug abuse and addiction, recent research advances, and their implications for prevention and treatment. Several NIDA-sponsored symposia targeting various aspects of substance abuse are also featured on this year's APA program. (2002-08-21)

Methamphetamine, cocaine abusers have different patterns of use
Studies show that methamphetamine abusers follow a pattern of usage that more closely resembles taking a medication rather than using a drug for pleasure whereas cocaine abusers are more likely to exhibit a (2002-07-31)

Methamphetamine drastically increases virus' ability to replicate in brain tissue
A controversial research study here has found that exposing cells infected with feline immunodeficiency virus - a surrogate for HIV - to methamphetamine increases those cells' ability to replicate the deadly virus as much as 15-fold. The finding could answer important questions about how lentiviruses such as FIV and HIV can gain a foothold in the brain. That knowledge is vital in slowing or lessening the dementia that often accompanies AIDS and similar diseases. (2002-06-05)

Brain shows ability to recover from some methamphetamine damage
A new brain-imaging study at the U.S. Department of Energy's Brookhaven National Laboratory indicates that some of the damage caused by methamphetamine -- a drug abused by ever-increasing numbers of Americans -- can be reversed by prolonged abstinence from the drug. The results appear in the December 1, 2001 issue of The Journal of Neuroscience. (2001-12-01)

Imaging studies expand understanding of how methamphetamine affects the human brain
Two recently published studies about methamphetamine offer additional insights about the actions of this drug in the brain. (2001-12-01)

Methamphetamine delivers 'one-two' punch to the brain
A new brain-imaging study at the U.S. Department of Energy's Brookhaven National Laboratory reveals that, compared with people who don't use drugs, people who abuse methamphetamine have fewer receptors for dopamine, a brain chemical associated with feelings of reward and pleasure. Furthermore, in the drug abusers, low dopamine receptor levels were linked with reduced metabolic activity in a brain region that regulates motivation and (2001-12-01)

Mother's drug use increases risks for male offspring
Exposure before birth to methamphetamine, an increasingly popular 'club' drug, renders males, even as adults, much more susceptible to the drug's brain-damaging effects. The increased toxicity could hasten the onset of brain disorders such as Parkinson's disease. (2001-07-13)

Researchers document brain damage, reduction in motor and cognitive function from methamphetamine abuse
Two studies by researchers at Brookhaven National Laboratory provide evidence for the first time that abuse of methamphetamine -- the drug commonly known as (2001-02-28)

Methamphetamine abuse leads to long-lasting changes in the human brain that are linked to impaired coordination and memory
Methamphetamine, a highly addictive stimulant drug, whose abuse has reached epidemic proportions in many parts of the United States, causes long-term changes in the human brain that are associated with impaired memory and motor coordination, according to a study published in the March 2001 issue of the American Journal of Psychiatry. (2001-02-25)

Dopamine receptors implicated in obesity
A deficiency of dopamine in the brain may explain why some individuals engage in pathological overeating, resulting in severe obesity, according to a study published in this week's Lancet. Based on their findings, the researchers believe that individuals deficient in dopamine may need to eat more than people with higher dopamine levels to induce feelings of satisfaction and gratification. (2001-01-31)

Blending addiction treatment and research

Brain contains cocaine-like chemical
A team of neuroscientists at the Yerkes Regional Primate Research Center have found that a neurotransmitter produces behaviors associated with cocaine and methamphetamine. The finding suggests a role for the brain chemical in modulating or mediating the actions of drugs and a perhaps potential new avenue for treating addiction. (2000-07-18)

Methamphetamine abuse linked to long-term damage to brain cells
National Institute on Drug Abuse research shows that those who use methamphetamine, often called (2000-03-26)

Drug Treatment Programs Don't Work
Drug rehabilitation programs don't work, says a professor of psychology at Oregon State University who has studied various approaches to this problem all over the world. His message to the countries he has worked in -- you can invest billions of dollars in drug treatment programs with very little effect. In the long run, the money would be better spent on prevention through education (1996-05-30)
