Question: urine test

 corpcuts - Mon Jun 28, 2004 10:29 am

My husband will be taking a urine test for a new job and he is wondering if the 2 prescription medications he is taking (Trazadone and Cyclobenzaprine) will show up and cause him to fail the test.

User avatar The basic drug test used by almost all testing programs (work, school, sports, and legal), checks for 5 groups of substances

Cannabis (marijuana, hashish, thc based substances)
Cocaine (cocaine, crack, benzoylecognine)
Amphetamines (speed, amphetamines, methamphetamine, etc)
Opiates (heroin, opium, codeine, morphine, etc)
Phencyclidine (PCP)

Here is the approximate time different drugs will be detected using a urine test. This does not mean that the drug is not present in your body, just that you will probably pass the test, if you get a urine test. Some of the substances listed are not tested for, they have been included as a reference.

Amphetamine 1 to 3 days
Methamphetamine 1 to 4 days
Barbituates (Short Acting 1 day) (Long Acting 2 to 3 weeks)
Cocaine 2 to 4 days
Codeine 2 to 5 days
Ecstasy 1 to 3 days
LSD 1 to 3 days
Marijuana 4 to 30 days or longer
Methadone 3 to 5 days
Mushrooms (that contain psilocybin) 1 to 3 days
Opiates 3 to 4 days
PCP 2 to 4 days

Tazodone belongs to a group of antidepressants called SSRIs while Cyclobenzaprine is a muscle relaxant. They are not included in the 'typical' drug abuse test. However, they can be detected in urine by the comprehensive drug screen. This can detect over 200 drugs. This is used mainly as a drug toxicity screen.
