Could A Saliva Test Detect Cannabis?

As a lifelong marijuana user, one of the biggest challenges I face is pre-employment drug testing. I have ranted before about how many types of tests unfairly target marijuana smokers so I will not get into that. My focus is specifically on saliva or spit tests. They are becoming increasingly prevalent in the workplace since they can be administered by an employer at the job site. The best thing about this test is it is very easy for marijuana smokers to pass!

Saliva (oral fluid-based) drug tests can are set up to detect use during the previous few days. Saliva tests, for the most part, are very difficult to adulterate. On-site oral based tests in enable the employer to randomly test employees, which is recognized to be the most effective type of drug screening. Testing is usually performed by employers, for either pre-employment, random, post-accident, reasonable suspicion, or return-to-duty testing. Saliva test provide results similar to the results of a blood test and is favorite for detecting on-the-job drug use or in post-accident testing.


Detection in saliva tests begins almost immediately after smoking and can be detected in the system for 12-24 hours after use. Compare this to other common drugs:

Marijuana and hash: 12-24 hours

Cocaine: 1 day
Opiates: Up to 2-3 days
Meth and ecstasy: Up to 2 to 4 days.
Alcohol: 6-12 hours

Wow! A drug test that is easier for weed smokers to pass then it is for a meth addict!

I’ve heard cases where people can smoke the same day and still pass! As a general rule, the easiest way to pass a saliva test is to stop smoking for a day or two prior to taking the test. Be sure to brush your teeth thoroughly and use mouthwash daily to clean out the potential toxins.

Of all the drug testing solutions employers use, the saliva test is the most weed friendly and the easiest to pass. If you have anymore tips or tricks, feel free to post them here for all to read and benefit from.

    Hey guys I recently posted on here pre drug test and I promised that I would post a post-drug test post so here it is. I had a Silvia drug test that I took on Saturday 21st of May. I was an avid smoker everyday until cinco de mayo when i burned my last tree, so a little over 2 weeks bud-free before I took the test. I passed the Silvia test for Publix and my preparation was drinking a lot of water within the last week leading up to the test. I read somewhere that if you drink a gallon of water the day of the test it helps dilute the results if you need to postpone the drug test (cause maybe they will let you come back and take it cause the results come back as diluted.) I did this shit and passed and now enjoying a fat bleezy to myself and my gf that I’m about to go have some fun with. good luck to all on future tests, and stay blazing.


    Hi all,
    I’m a heavy smoker, who hasn’t smoked in 2weeks, n had take a oral mouth swab today, waiting for results. You guys think I have any chance to pass?

    All I did was brush my teeth n flossed before test



    I just smoked saturday night. It wasnt much just a few hits. But i went in monday around 3pm and a couple hours after being at work they called me in for a random saliva drug test. Do you think i will pass or should i be worried? Cause it was only a day in a half between the time i smoked and the time i took the test.


    I smoked last night and took the oral drug test today at 12:40 i had a friend do the same and passed but everyone is different will this be a problem ?


    I smoke every day but have only smoked on at about noon today and got a call for a job today and have to go in tomorrow. . what should i do to be able to pass this test its for a good job


    Being only 15, this is really great news! I just got back from my saliva test for my new job and I haven’t smoked in over a week. I was worried to death that I would test positive. This sure would be a shitty way for my mother to find out i smoked pot…


    I stopped smoking on June 30th and I had a mouth swab on July 13th the stick didn’t turn blue tho… I think it’s because of the lack of salvia I had at the time. Do you think I passed?


    I smoke a day ago how long it take to get out my system


    Hey guys I thought I’d just share my experience with everyone and hopefully it’ll ease some people’s minds. I smoked a bowl and took a few hits from a blunt roughly 60 hours before my drug test. I had no idea I was going to get tested that day so I did nothing other than my regular routine of just brushing my teeth. I did not chug an insane amount of water (I probably barely drank any), brush my gums or cheeks, use mouthwash, listerine strips, gum, or anything like that. When I took my drug test it was one of long sticks that you keep in your mouth. I had it in there for 10 minutes, it touched my cheek and took a lot of saliva. Questlab was where my company sent my swab test to and it came back negative. In short, I looked up questlab and even on their site they claim that it will detect drugs up to the 48 hour window. It seems that the safest bet is to be 72 hours clean and at the very least brush your teeth. Hope this helps guys!


    You can buy saliva and urine drug test kits on Amazon etc (CVS etc. also) and test yourself fyi…good way to test supposed remedies, procedures etc


    Brush your teeth and the inner cheeks. Use mouthwash right before going in.


    I smoke weed last month and here in our school will be having drug test next week wednesday you think ill past the drug test


    I got pulled over by the cops about 48hours after smoking quite a lot. The test came out negative.


    Yes and they took a saliva test – forgot to mention that


    I’ve taken two of these tests now, the first one years ago I had smoked the previous day and came out clean. Just today I took another one and I had just smoked a dirty bowl the hour before. I didn’t even brush my teeth before hand, (maybe the tobacco covered up the ganja?) because I was expecting a piss test and I brought clean pee with me. I was pretty nervous when they gave me the mouth swab but, hey, I’m starting the job tomorrow


    So ladies and gentlemen I got this I information directly from the quest labs website-
    What is the detection window for drugs in oral fluid?
    While every drug and donor is different, oral fluid is widely regarded as the most reliable specimen type for detecting recent use. Oral fluid is able to detect most drugs starting soon after ingestion and extending out for 24-48 hours after use.


    I have to take random weekly swabs and I find that if I abstain for 24 hours I generally pass. I’ve even had many times that I have smoked the night before and passed in the morning. My counselor has also told me that he has many patients who admittedly smoke marijuana and do not come up positive. I don’t do anything fancy for mouth care. There have been times that I was so rushed in the early morning that I didn’t have time to brush my teeth and still pass. As far as I know it’s really just a time thing with saliva testing for marijuana. I got info from Quest laboratories website and they say maximum detection time for marijuana is 24-48 hours


    I smoked a mix of Sour Diesel, Purple Mr.Nice and Bubba Kush at 11pm. The next day I was suppose to take a urine drug test but got changed to a saliva test. Which was administered at 11:15 am and passed. Didn’t do anything special just brushed my teeth as normal.


    Wash mout

    h with peroxide right before and you’ll pass … speaking from experience.
