Steroids
As
athletes gathered at the 2000 Olympic Games in Sydney,
Australia, the issue of performance enhancing drugs,
especially anabolic steroids, once again gained international
attention. These drugs are used by high school, college,
professional, and elite amateur athletes in a variety
of sports (e.g. weight lifting, track and field, swimming,
cycling, and others) to obtain a competitive advantage.
Body builders and fitness buffs take anabolic steroids
to improve their physical appearance, and individuals
in occupations requiring enhanced physical strength
(e.g. body guards, night club bouncers, construction
workers) are also known to use these drugs.
Concerns
over a growing illicit market, abuse by teenagers, and
the uncertainty of possible harmful long-term effects
of steroid use, led Congress in 1991 to place anabolic
steroids as a class of drugs into Schedule III of the
Controlled Substances Act (CSA). The CSA defines anabolic
steroids as any drug or hormonal substance chemically
and pharmacologically related to testosterone (other
than estrogens, progestins, and corticosteroids) that
promotes muscle growth.
Once
viewed as a problem associated only with professional
and elite amateur athletes, various reports indicate
that anabolic steroid abuse has increased significantly
among adolescents. For example, the National Institute
on Drug Abuse 1999 Monitoring the Future survey reveals
that more than a half million 8th and 10th grade students
were using anabolic steroids. Abuse is higher among
males than females, but is growing most rapidly among
young women.
Most
illicit anabolic steroids are sold at gyms, competitions,
and through mail operations. For the most part, these
substances are smuggled into the United States from
many countries. The illicit market includes various
preparations intended for human and veterinary use as
well as bogus and counterfeit products. The most commonly
encountered anabolic steroids on the illicit market
include testosterone, nandrolone, methenolone, stanozolol,
and methandrostenolone. Other steroids seen in the illicit
market include boldenone, fluxoymesterone, methandriol,
methyltestosterone, oxandrolone, oxymetholone, and trenbolone.
A
limited number of anabolic steroids have been approved
for medical and veterinary use. The primary legitimate
use of these drugs in humans is for the replacement
of inadequate levels of testosterone resulting from
a reduction or absence of functioning testes. Other
indications include anemia and breast cancer. Experimentally,
anabolic steroids have been used to treat a number of
disorders including AIDS wasting, erectile dysfunction,
and osteoporosis. In veterinary practice, anabolic steroids
are used to promote feed efficiency and to improve weight
gain, vigor, and hair coat. They are also used in veterinary
practice to treat anemia and counteract tissue breakdown
during illness and trauma.
When
used in combination with exercise training and high
protein diet, anabolic steroids can promote increased
size and strength of muscles, improve endurance, and
decrease recovery time between workouts. They are taken
orally or by intramuscular injection. Users concerned
about drug tolerance often take steroids on a schedule
called a cycle. A cycle is a period of between 6 and
14 weeks of steroid use, followed by a period of abstinence
or reduction in use. Additionally, users tend to "stack"
the drugs, using multiple drugs concurrently. Although
the benefits of these practices are unsubstantiated,
most users feel that cycling and stacking enhance the
efficiency of the drugs and limit their side effects.
Another
mode of steroid use is called "pyramiding."
With this method users slowly escalate steroid use (increasing
the number of drugs used at one time and/or the dose
and frequency of one or more steroids), reach a peak
amount at mid-cycle and gradually taper the dose toward
the end of the cycle. The escalation of steroid use
can vary with different types of training. Body builders
and weight lifters tend to escalate their dose to a
much higher level than do long distance runners or swimmers.
The
long-term adverse health effects of anabolic steroid
use are not definitely known. There is, however, increasing
concern of possible serious health problems associated
with the abuse of these agents, including cardiovascular
damage, cerebrovascular toxicity, and liver damage.
Physical
side effects include elevated blood pressure and cholesterol
levels, severe acne, premature balding, reduced sexual
function, and testicular atrophy. In males, abnormal
breast development (gynecomastia) can occur. In females,
anabolic steroids have a masculinizing effect, resulting
in more body hair, a deeper voice, smaller breasts,
and fewer menstrual cycles. Several of these effects
are irreversible. In adolescents, abuse of these agents
may prematurely stop the lengthening of bones, resulting
in stunted growth.
With some individuals the use of anabolic steroids may
be associated with psychotic reactions, manic episodes,
feelings of anger or hostility, aggression, and violent
behavior.
A
variety of non-steroid drugs are commonly found within
the illicit anabolic steroid market. These substances
are primarily used for one or more of the following
reasons: 1) to serve as an alternative to anabolic steroids;
2) to alleviate short-term adverse effects associated
with anabolic steroid use; or 3) to mask anabolic steroid
use. Examples of drugs serving as alternatives to anabolic
steroids include clenbuterol, human growth hormone,
insulin, insulin-like growth factor, and GHB. Drugs
used to prevent or treat adverse effects of anabolic
steroid use include tamoxifen, diuretics, and human
chorionic gonadotropin. Diuretics, probenocid, and epitestosterone
may be used to mask anabolic steroid use.
Over
the last few years, a number of precursors to either
testosterone or nandrolone have been marketed as dietary
supplements in the United States. Some of these substances
include androstenedione, androstenediol, norandrostenedione,
norandrostenediol, and dehydroepiandrosterone (DHEA).
TRAFFICKING
The
Anabolic Steroid Control Act was passed by Congress
in the fall of 1990 and became effective on February
21, 1991. The Steroid Act classified 27 steroids as
Schedule III substances under the CSA. Street prices
of anabolic steroids have increased substantially as
a result.
Fitness
clubs have been, and continue to be, the primary distribution
centers of steroids, since bodybuilders and weightlifters
comprise a predominant portion of the user population.
Once viewed as a problem strictly associated with professional
athletes, a recent survey of students indicates increased
steroid use among boys in the 8th and 10th grades. The
percentage of 8th grade boys reporting past-year use
of steroids increased from 1.6 percent in 1998 to 2.5
percent in 1999, and from 1.9 percent to 2.8 percent
among 10th grade boys.
Anabolic
steroids are illicitly smuggled from Mexico and European
countries to the United States. Recent DEA reporting
indicates that Russian, Romanian, and Greek nationals
are significant traffickers of steroids and are responsible
for substantial shipments of steroids entering the United
States. The lack of international control over foreign
sources of supply, however, makes it impossible to attack
the trafficking at its source. |
