TUESDAY, Dec. 14 (HealthDay News) -- People who consume moderate
amounts of alcohol may be at increased risk for amphetamine abuse,
according to a new study.
Amphetamines belong to a large group of drugs called stimulants,
which can increase energy and concentration and are widely abused
by young adults.
U.S. researchers categorized 33 volunteers as either moderate
(more than seven drinks a week) or light drinkers (fewer than seven
drinks a week) and gave them both low (8 to 10 milligrams) and high
(16 to 20 milligrams) doses of d-amphetamine.
After receiving the initial dose, the participants could earn up
to eight capsules containing 12.5 percent of the previous dose by
working on a computer task. The high dose of amphetamines increased
drug taking in both light and moderate drinkers, while the low dose
did so only in moderate drinkers.
The moderate drinkers also did the computer tasks in order to
receive the high dose of amphetamine. This indicates that moderate
levels of alcohol may increase a person's vulnerability to the
effects of stimulants such as amphetamine, reported senior author
Craig R. Rush, a professor of behavioral science, psychiatry and
psychology at the University of Kentucky, and colleagues.
The study findings are published online and in the March 2011
print issue of the journal
Alcoholism: Clinical & Experimental Research.
Further research is needed to fully understand the association
between drinking and stimulant abuse, the researchers
