URINALYSIS
Urinalysis is an older drug testing technology. This method has some
problems that have been exploited by drug users.
DETECTION PERIOD
Urinalysis can generally detect drug use for the previous 2-3 days
for most drugs. After that the body flushes out the substance. A drug user
can simply abstain for a short period of time, drink water, take the urine
test and pass!
EASE OF EVASION
Drug users can substitute clean samples, or tamper with urine specimens.
Information about "beating urine tests" is widely available and advertisements
for "clean urine" and urine adulterating products are prevalent on the
Internet. Beating a urine test is "no big deal" for an experienced drug
user.
INTRUSIVE COLLECTION
The act of collecting a urine sample is intrusive
and unpleasant. Also, to decrease the ability to tamper with the sample,
urine collections should be observed. This causes further uneasiness -
particularly for women.
BLOOD TESTING
DETECTION PERIOD
Short - usually only hours.
COLLECTION PROBLEMS
With the fear of blood borne infectious diseases, drug testing with
blood is not usually the preferred method. Blood testing is the least used
and recommended form of drug testing because of the invasiveness of the
collection, the need for skilled sample takers and the extremely short
detection period.
HAIR TESTING
DETECTION PERIOD
Psychemedics hair analysis can detect drug use for several months. Temporary abstention won't
beat the test.
EVASION
Psychemedics hair testing cannot be evaded as in urinalysis since the
drug residue remains permanently entrapped in the hair.
COLLECTION
A cosmetically undetectable snip of hair is easily collected without
causing embarrassment. Collection can be done in-house saving the
time, inconvenience and the cost of having a job applicant visit a urine
collection site. Blood testing is the least used and recommended form of
drug testing because of the invasiveness of the collection, the need for
skilled sample takers and the extremely short detection period.
