Saliva drug testing is a great alternative to urine screening, however it does have it’s drawbacks. Here are a few facts about oral fluid drug screening.
Saliva screening has become a popular method of drug testing in recent years. The need for validity tests with oral fluid testing is minimized because of the observed collection process. Furthermore, it elevates the situation of male testing female and vice versa.
In general the detection times for oral fluid drug testing are less than urine drug testing. For example, many drugs (cocaine, opiates, methadone, and amphetamine) are detected in urine for up to three days after cessation of use; they are detected in oral fluid for up to two days. THC metabolite detection in urine depends on the pattern of use, i.e. occasional vs. frequent. Cannabinoids are often cited as being detected in urine for up to 30 days after stopping use. Oral Fluid THC screens primarily for the presence of parent drug and is detected for up to 24 hours after use.
