What Drugs Will Cause A Positive Test Result?

Most prescription medicine will not cause a positive test. For example, use of AZT, lithium, anti-depressants, antibiotics, tranquilizers/sleeping pills, medicine for diabetes and epilepsy will not show up. Legitimate explanations for positive results, according to the National Institute on Drug Abuse, include the following:

Marijuana: THC can be used as an antiemetic for cancer chemotherapy patients with intractable vomiting. Passive inhalation of marijuana will not explain a positive test because the cut off for the first test is 100 ng? ml. Only prescription use is acceptable.

Cocaine: It is useful as an anesthetic and vasoconstrictor for certain types of surgery involving the nose, throat, larynx, and lower respiratory passages. Only dosages administered by doctors or dentists are acceptable.

Amphetamines: Although they can be used to treat narcolepsy, attention deficit disorder, depression that has not responded to other treatments, their use is controversial because of the risk of abuse. Amphetamine-related drugs, e.g. asthma medication with ephedrine, over-the-counter cold and hayfever medications with phenylpropanolamine and some vasodilators are not expected to produce a confirmed positive test; however, the Medical Relief Officer (MRO) is advised to carefully question individuals testing positive for amphetamines about their prescribed medications.

Opiates: Many prescription drug contain codeine or morphine and will thus produce a "true" positive opiate result. A legitimate prescription which explains the test results means the MORO must report the test as a negative. Some caught suppressing and antidiarrheal preparations contain paregoric with sufficient anhydrous morphine to produce a morphine/codeine positive test. Recent ingestion of poppy seeds may be a cause of opiate positive urine. Therefore, before the MRO can verify a confirmed positive test for opiates, ( which does not indicate  heroin use) the MRO must find other signs of drug abuse, like needle tracks or signs of intoxication or withdrawal, or report the test as negative.

Consequences Under the FAA Regulations
The regulations require that any covered employee who has a verified positive drug test or who refuses to be drug tested must immediately be removed from a safety-sensitive position and be referred to a Substance Abuse Professional (SAP) for evaluation and treatment as necessary. You can be permanently barred from performing your safety-sensitive function at any employer if you:

1. Engage in prohibited drug use during the performance of your safety-sensitive function; or
2. Have a verified positive drug test results on two drug tests conducted after September 19, 1994.
BOTTOM LINE: YOU WILL LOSE YOUR JOB AND THE ODDS OF WINNING IT BACK ARE SLIM TO NONE.
