• Saliva or oral fluid or testing results for the most part mimic that of blood. The only exclusion is THC. Oral fluid will likely detect THC from ingestion up to period of 18-24 hours.

• Urine can not detect recent drug use. It takes about 6-8 hrs. after consumption for drug to be metabolized and excreted in urine. Similarly, hair requires two weeks and sweat seven days.
