Erowid Drug Testing Vaults : The Basics
5. Phencyclidine (PCP)
Expanded Tests
Most drug testing companies also offer an expanded test which includes a few additional drugs
in the testing process. Most do not add all of these in their expanded test, but choose a different
combination of 3 or 4 to add :
1. Barbituates (Phenobarbital, Secobarbitol, Butabital)
2. Methaqualone (Qualuudes)
3. Benzodiazepines (Valium, Librium, Serax, Rohypnol)
4. Methadone
5. Propoxyphene (Darvon compounds)
6. Ethanol
Additional Testables
In addition, there are a few other substances which it is possible but quite unusual to test for. I
only found reference to testing for these additional substances at 1 (out of 15) drug testing site :
1. LSD
2. Hallucinogens (Psilocybin, Mescaline, MDMA, MDA, MDE)
3. Inhalents (Toluene, Xylene, Benzene)
TEST TYPES
There are three primary types of drug tests: blood, urine, and hair. Most common is the urine test
which has the benefit of being inexpensive and less intrusive than the blood test.
Urine Tests
● Are the least expensive of the test methods (~$25-$50)
● Can be done at home (for example by parents).
● Detect use primarily within the past week (longer with regular use).
● Can be affected by abstaining from use for a period of time before the test
● Are often temperature tested to insure sample integrity
Hair Tests
● Are considered the least intrusive method of drug testing.
● Are currently many times more expensive than urine tests (~$100-$150).
● Detect substance use over a longer period (see detection period)
● Do not usually detect use within the past week.
