Drug Approximate Detection Time in Urine using EMIT
- ----------------------------- ----------------------------------------------
Amphetamines 2-4 days
Barbituates
Short-Acting (ie. secobarbital) 1 day
Long-Acting (ie. phenobarbital) 2-3 weeks
Benzodiazepines 3-7 days
Cannabinoids 3-30 days
Clenbuterol [PE] 2-4 days [F1]
Cocaine 2-4 days
Codeine 2-5 days
Euphorics (MDMA,psilocybin) 1-3 days [F2]
LSD 1-4 days [F6]
Methadone 3-5 days
Methaqualone 14 days
Nicotine ? [F5]
Opiates 2-4 days
Peptide hormones [PE] undetectable
Phencyclidine (PCP) 2-4 days [F4]
Phenobarbital 10-20 days
Propoxyphene 6 hours to 2 days
Steroids (anabolic) [PE] oral: 14 days [F3]
parenterally: 1 month [F3]
[PE] Performance Enhancers
[F1] 0.5 ng/mL by GC/MS
[F2] By RIA and GC/MS only. Not Detectable by EMIT.
[F3] By HPLC, RIA, and GC/MS. Not Detectable by EMIT.
[F4] 8-14 days as was reported in earlier versions and was incorrect.
[F5] No data available yet. I expect the detection time to be long because
nicotine is fat soluble.
[F6] Detectable by EMIT and RIA, but rarely tested. A lab will only test for
LSD when specifically requested.
Note: Detection times vary depending on analytical method used, drug
metabolism, tolerance, patient's condition, fluid intake and method and
frequency of ingestion. These are general guidelines only.
