Study: Drug use causes
permanent changes

By Jessica Mass
Daily Staff Reporter
A high percentage of college students using il-
licit drugs, including marijuana, heroin and cocaine,
signals the possibility of high rates of addiction
among college students.
A new study by Kent C. Berridge and Terry E.
obinson, two University researchers, found that drug
addiction causes permanent changes in the
neurosystems of the brain and that addicts may crave
drugseventhough the drugsdonotgive thempleasure.
Additionally, the study establishes a difference
between the neural processes of wanting and liking.
"Most people assume that addicts take drugs ei-
ther to get pleasure or to avoid unpleasant conse-
quences of withdrawal," Berridge said. "But the

truth is that addicts continue to seek drugs even
when they don't derive any pleasure from them, and
relapse is a potent danger long after detoxification
and recovery from withdrawal."
Thestudy foundthat whenaddictive drugssuchas
heroin, cocaine and amphetamines are taken repeat-
edly, specific brain regions become more sensitized.
"Addiction can be triggered by anything paired
with the drug in the past," Berridge said. "When
these things are present, they can put a person into
extreme craving even if they've already gone
through withdrawal."
Berridge said this theory of addiction can also ap-
ply to alcohol and, to some extent, to nicotine.
The study also identifies what would be needed
to make a chemical cure for addiction. "The drug

would have to reverse neural changes that cause su- illicit drugs, making addictiona problem that many
per-excitability," Berridge said. college students confront.
According to the National Institute on Drug "The study explains why (students) mightexperi-
Abuse, 86.5 percent of college students use alcohol, ence intense (drug) cravings, and it can help them to
38.8 percent smoke cigarettes and 30.6 percent use understand the changes in themselves,"Berridge said.
