Drug
Detection Times
|
Drug
Detection Times in urine are expressed below in
terms of lower and upper boundaries. The amount of
time that a drug/metabolite remains detectable in
urine can vary, depending on the following factors:
|
|
|
| · |
Amount
and Frequency of Use: Single, isolated, small doses
are generally detectable at the lower boundary.
Chronic and long-term use typically result in
detection periods near or at the upper boundary. |
|
|
| · |
Metabolic
Rate: Individuals with slower body metabolism are
prone to longer drug detection periods. |
|
|
| · |
Body
Mass: In general, human metabolism slows with
increased body mass, resulting in longer drug
detection periods. In addition, THC (marijuana's
active ingredient) and PCP are known to accumulate
in fatty lipid tissue. Chronic users, physically
inactive users, and individuals with a high
percentage of body fat in relation to total body
mass are prone to longer drug detection periods for
THC and PCP. |
|
|
| · |
Age:
In general, human metabolism slows with age,
resulting in longer drug detection periods. |
|
|
| · |
Overall
Health: In general, human metabolism slows during
periods of deteriorating health, resulting in longer
drug detection periods. |
|
|
| · |
Drug
Tolerance: Users typically metabolize a drug
faster once a tolerance to the drug is established. |
|
|
| · |
Urine
pH: Urine pH can impact drug detection periods.
Typically, highly acidic urine results in shorter
drug detection periods. |
|
|
| · |
Note:
In a small percentage of cases, users may test
positive longer than times shown - most notably in
cases of long-term chronic abuse, in individuals
with significant body mass and/or body fat, and in
individuals with health related issues resulting in
abnormally slow body metabolism. These detection
times are based on urine analysis. Detection times
for hair follicle, blood and saliva tests are much
higher. |

Drug
Group
|
Time
Range
|
| Alcohol |
24
hours or less |
| Amphetamines |
1
to 5 days |
| Barbiturates |
Short-acting:
1 to 5 days |
| Long-acting
(Barbital, Phenobarbital): 1 to 3 weeks |
| Benzodiazepines |
Short-term
Therapeutic Use: 1 to 5 days |
| Long-term
/ Chronic Use: 1 to 3 weeks |
| Cocaine |
1
to 5 days |
| LSD |
1
to 5 days |
| Marijuana
(THC) |
Casual
Use: 1 to 10 days |
| Long-Term
/ Chronic Use: 1 to 4 weeks |
| Note:
THC, marijuana's primary active ingredient, is
stored by the body in fatty lipid tissue. From
there, it is slowly released into the bloodstream
for up to several weeks - depending on the amount
and frequency of use and the user's level of
physical activity. In chronic and physically
inactive users, THC may accumulate in fatty tissues
faster than it can be eliminated. This accumulation
leads to longer detection periods for these
individuals. Also, users with a high percentage of
body fat in relation to total body mass are prone to
longer drug detection periods for marijuana. |
| MDMA
(Ecstasy) |
1
to 7 days |
| Methadone |
1
to 7 days |
| Methamphetamines |
1
to 7 days |
| Opiates |
1
to 8 days |
| PCP
(Phencyclidine) |
Casual
Use: 1 to 10 days |
| Long-Term
/ Chronic Use: 1 to 4 weeks |
| Note:
PCP is stored by the body in fatty lipid tissue.
From there, it is slowly released into the
bloodstream for up to several weeks - depending on
the amount and frequency of use and the user's level
of physical activity. In chronic and physically
inactive users, PCP may accumulate in fatty tissues
faster than it can be eliminated. This accumulation
leads to longer detection periods for these
individuals. Also, users with a high percentage of
body fat in relation to total body mass are prone to
longer drug detection periods for PCP. |
