What drugs do tests detect?

Testing conducted according to English guidelines checks for five illicit drugs plus, in some cases, alcohol (ethanol, ethyl alcohol, booze).  These five illicit drugs are: 

  • Amphetamines (meth, speed, crank, ecstasy)
  • THC (cannabinoids, marijuana, hash)
  • Cocaine (coke, crack)
  • Opiates (heroin, opium, codeine, morphine)
  • Phencyclidine (PCP, angel dust)  

However, most private employers are not limited in the number of substances they can test for and may include drugs that individuals legitimately and/or therapeutically take based on a physician’s prescription.  Although most private employers can test for any combination of drugs, there are commonly selected “panels.” 

The typical 8-Panel Test includes the above-mentioned substances plus:

  • Barbiturates (phenobarbital, butalbital, secobarbital, downers)
  • Benzodiazepines (tranquilizers like Valium, Librium, Xanax)
  • Methaqualone (Quaaludes)

The typical 10-Panel Test includes the 8-Panel Test plus:

  • Methadone (often used to treat heroin addiction)
  • Propoxyphene (Darvon compounds)

Testing can also be done for:

  • Hallucinogens (LSD, mushrooms, mescaline, peyote)
  • Inhalants (paint, glue, hairspray)
  • Anabolic steroids (synthesized, muscle-building hormones) 
  • Hydrocodone (prescription medication known as Lortab, Vicodin, Oxycodone)
  • MDMA ( commonly known as Ecstasy)

How long are drugs in one’s system?

Drugs have certain “detection windows”—the amount of time after ingestion during which evidence of their use can be detected by a drug test.  Though it might not be wise to publicize detection windows and invite employees who may use drugs to push their limits, when implementing drug testing, it is important to understand them.  For instance, alcohol is absorbed and eliminated more quickly than other drugs.  This is why post-accident testing procedures often require testing for alcohol to occur within two hours.  Other drugs are eliminated from the system at different rates and thus detectable for different periods of time, often long after the drug’s effect has worn off.  The following are estimates of the length of time that certain drugs are detectable: 

  • Alcohol – 1 oz. for 1.5 hours 
  • Amphetamines – 48 hours 
  • Barbiturates – 2-10 days 
  • Benzodiazepines – 2-3 weeks 
  • Cocaine – 2-10 days 
  • Heroin Metabolite – less than 1 day 
  • Morphine – 2-3 days 
  • LSD – 8 hours 
  • Marijuana – casual use, 3-4 days; chronic use, several weeks
  • Methamphetamine – 2-3 days 
  • Methadone – 2-3 days 
  • Phencyclidine (PCP) – 1 week
