Typical work drug tests screen for one or all of the following four substances: cannabinoids (THC), amphetamines, cocaine, or opioids. Of these main categories of drugs that are usually tested on work-related drug tests, marijuana is known to last the longest time in the system; up to 30 days for some users and as much as 60 days for heavy users, depending on the type of test performed and other important factors.
Since it is less invasive and simpler to obtain, many employers see a saliva test as an improvement on the popular urine drug test (UDT). Research indicates that the exposure to cannabinoids must be much more recent to be detected in a saliva test, with some experts indicating that the exposure must be within a few hours of providing the saliva sample (ranging from 4 to twelve hours, depending on the authority). Other studies indicate that saliva tests can be effective in detecting cannabis use within the past 4 days. Since you want to know how to pass the drug test, it is important to know the facts related to the particular type of screening you are asked to undergo. With some research of your own based on the type and brand of the test, you can determine the effective parameters of the test you are subjected to, and be prepared to discuss some of the questions that may legitimately arise about the drug test you are asked to pass.
The drug test that is most effective at revealing potential impairment from recent marijuana use is from a blood sample. Typically used by police departments in cases involving automobile marijuana DUI investigations, a blood drug test can usually reveal the presence of actual THC in the bloodstream for hours after smoking. For some heavy regular marijuana users, a blood test may produce a positive result even a day or so after last smoking, although the presence of active THC may not persist for that time. If involved in an automobile case and a drug test is an issue, the timely advice of a competent lawyer may be crucial to the outcome of your case. As always, do your best to know your rights, ask good questions, and stay informed as to how to pass your drug test when important rights are involved.
Another recent development in drug testing technology is the use of a patch placed on the skin to sample for the presence of prohibited drugs secreted in the perspiration while you are wearing the patch. Generally ordered by courts for those on probation or in disputes over child custody, for example, skin patch perspiration tests are unlikely to be required by an employer in most cases. On the other hand, though, this type of test is perhaps one of the most difficult to evade detection of drug use when it is ordered, as the patch is to remain on the subject’s skin for some two weeks and measure drug metabolites sensed in the person’s sweat throughout that time.
