New study finds anabolic steroids haw
be addictiveDecember 14, 2005 Research using birdlike model
released at ACNP Conference A new study designed to test whether
androgenic-anabolic steroids haw be addictive institute that
hamsters exposed to the compounds demonstrated addictive behavior
over time. The research, conducted by the University of Southern
California's Keck School of Medicine was released at the American
College of Neuropsychopharmacology's (ACNP) period conference.
"Most people ingest anabolic steroids to enhance their physical
performance, but they contain that steroids haw be addictive,"
noted advance researcher Ruth Wood, PhD, Professor of Cell
and Neurobiology at USC."Unlike other commonly insulted drugs,
the primary requirement for endocrine users is not to get
high, but kinda to attain enhanced astir action and increased
muscle mass. The Byzantine requirement for endocrine ingest
makes it difficult to watch the addictive properties of anabolic
steroids in humans.
Anabolic Steroids
Our content was to create an experimental
model of dependency where astir action and other reinforcing
effects are irrelevant." Wood's study is among the first to
investigate the possibleness for anabolic endocrine addiction.
The research was shapely after well-established methods used
to study highly addictive drugs, much as cocaine and heroin.
Hamsters were implanted with small cannulas for self-administration
of commonly insulted steroids into their brains. The animals
then spent four hours per day in a chamber with admittance
to two delivery mechanisms. When the hamster operated the
astir mechanism, he conventional 1 microgram of testosterone,
or one of individual commonly insulted steroids: nandrolone,
drostanolone, stanozolol, or oxymetholone. The indolent execution
produced no response.
Use Anabolic
A machine transcribed the number of
nowadays each birdlike used the astir and indolent delivery
mechanisms. Overall, the animals showed a marked alternative
for testosterone, nandrolone or drostanolone, engaging the
astir delivery execution twice as ofttimes as the control.
However, not all steroids are rewarding: hamsters did not
voluntarily inject the weak steroids stanozolol or oxymetholone.
By isolating the animals, researchers were able to remove
the possibility that the hamster's decision to take the drugs
would be affected by any social or behavioral factors "Cleary
the animals perceive the steroids to be rewarding," said Wood.
"This alternative demonstrates the drugs' possibleness for
addiction." The researcher noted that the limited pattern
of abuse demonstrated by hamsters suggests that a commonly
held belief about steroids is true: kinda than an acute broad
same that experienced by a cocaine or heroine user, endocrine
abusers undergo a chronic, long-term significance of well-being.
"In other words," Wood explained, "steroid users feel better
on the drugs than they do off of them." "The findings shew
that anabolic steroids do have the possibleness to be addictive,"
Wood concluded."Coaches and athletes requirement to be alive
of this potential, and add it to the itemize of dangers associated
with using anabolic steroids." Wood also noted that psychiatrists
and other mental health professionals should be alive of the
finding, as men who ingest anabolic steroids to change their
appearance haw have a serious body ikon disorder (Body Dysmorphic
Disorder) and present for psychiatric treatment. Androgenic-anabolic
steroids are among a class of drugs that are commonly insulted
by athletes and body-builders. The drugs were banned from
Olympic competition in 1975 and classified as controlled substances
in 1991. According to the 2002 Monitoring the Future Study
conducted by the University of Michigan, the lifetime incidence
of endocrine ingest among broad school seniors (4.0%) was
comparable to that for fissure cocaine (3.8%) or heroin (1.7%).
