I know that saliva tests only detect MJ for a pretty short time period 3-4 days max. I know this since I passed one last summer after only quitting for like 3 days(smoked purple stuff and hydro almost everyday for 5-6 years). I was just wondering if there are any " NEW" saliva tests that can detect as far back as 15-30 days. I doubt it but Im just checking since my fuckin school is about to start orally drug testing us in September-pitifull.
