We get a lot of emails from people who are just downright frightened about an upcoming drug test. Pretty understandable especially when there is a lot on the line. Our recommendation is to do your research and ask questions. Make informed decisions about what direction you will take to pass your drug test. This is not a guarantee that [...]

Alcohol: Not part of the SAMSHA 5 standard drug screen panel, however an alcohol drug test can be included as part of an extended drug screen. Rarely used in employment screenings. For urine testing of EtG, a metabolite of Alcohol, there are some claims that detection of EtG can be up to 5 days from the last drink consumed. However, drug testing labs are now starting to say that 80 hours is a more realistic limit. The actual time really depends on how much alcohol you have consumed and the rate your liver metabolizes alcohol. For example, in an extreme case where someone with a slower liver metabolism, consumed 7 shots of whiskey in a 4 hour period, the detection time would be closer to the 80 hour period. On the other hand, someone with a fast liver metabolism who drank 2 shots of whiskey in a 4 hour period would most likely see a detection time of 24 hours.

Hair testing for EtG has a standard 90 day detection time. However, there was a study done in Italy at the University of Pavia in 2009, which showed hair treated with a strong high PH treatment, made the EtG disappear from the hair matrix, most likely via removal from the Keratin matrix. This study has casted doubts on the effectiveness of EtG testing in hair. Another hair test done to look for alcohol consumption is an FAEE (Fatty Acid Ethyl Esthers) test. FAEE's are alcohol metabolites that enter the hair strand through sebum (oil secreted by skin). Unlike EtG, FAEE levels are not reduced by the use of strong PH hair treatments. However, a German study published in 2011 in Forensic Science International, showed that use of hair products that contain alcohol, actually increased the levels of FAEE's in the hair. This causes high rates of false positives. For this reason, good testing labs will test both FAEE's and EtG on a hair sample to give the most accurate results.

Amphetamines: Part of the SAMSHA 5 standard drug screen panel

Barbituates: Not part of the SAMSHA 5 standard drug screen panel, however can be included as part of an extended drug screen. Barbiturates can be broken down into two classes when it comes to detection periods; short acting and long acting. Short acting simply means this type has a shorter half life (stays in the body a shorter amount of time) than a longer acting barbiturate.

Cannabis Sativa or THC: Part of the SAMSHA 5 standard drug screen panel. THC detection time in urine is dependent on 5 main things: frequency of use, length of time of use, potency or concentration of THC in the Cannabis, body fat %, and the body's metabolic rate. For this reason it is difficult to give an easy answer on detection times. But in the most extreme situation, for example, an inactive person with a high body fat % who uses cannabis with a high THC concentration on a daily basis, can expect around a 90 day urine detection period, from the last use. This must be considered for hair testing as well. While existing hair growth that contains THC metabolites can only be detected accurately for up to 90 days, the fact that it can reside in the body for up to 90 days after the last use, means newly formed growth containing detectable THC metabolites can continue for 6 months.

Cocaine: Part of the SAMSHA 5 standard drug screen panel. Cocaine is a water soluble drug, so it leaves the body fairly quickly. It has a low detection time in urine, blood and saliva testing, except for in heavy users, where detection in urine can be a few weeks. Because of the low detection time in urine, blood and saliva, hair testing for cocaine is the most accurate way to detect use. Hair testing for cocaine is very sensitive, and can detect a single use for up to 90 days.strong>Cocaine: Part of the SAMSHA 5 standard drug screen panel.
