Drug TestingCould 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.

    I am an every day smoker and today I was given an oral test today after killing an interview and being hired on the spot. I smoked a solid 8 hours before but I did floss and brush and hit the mouth wash before the interview. I am happy as I am very good at what I do and feel that smokers have been shit on my entire life. (im 40 but look 25 ladies)

    I read most of these comments and I had to say very impressive. I had a drug test today (saliva) so on the day before I got that call asking could I come in that day before 4pm or today at 12pm lol of course I said today at 12pm because I had just got finished smoking a blunt. I googled how to beat a saliva test for weed and I seen this ad first. I brought some altoids mints, peroxide and mouth wash. Did that a couple times went in and passed, and im 29 289pds.

  • Trixie

    I am a chronic smoker and I just got a call asking to come in and interview Friday. I looked online and other people said that the employer does the swab testing. I am not sure if they may swab test me this Friday or maybe at a later date, after another interview. Should I stop smoking weed now to pass the swab test on Friday? I would like to get this job too. If I finish smoking this huge joint I rolled thats a collection of roaches and then don’t smoke until Friday do you think I would pass???

    • Canon843

      Yes, You will most certainly pass. Those type of test only go back 12-24 hours. Drinking water and any other bev right before the test could help if you’re really worried (I wouldn’t be but…) (thc is stored in fat cells therefore fat soluble). SWIM smoked the night before an 8am swab test and passed and they are a semi regular smoker. Hope this helps. Let us know what happens please. We could all use as many real life example as possible.

      • Trixie

        I have the group interview in a few hours. It has been really difficult for me not to smoke. Last time I smoked was last night about 7pm. I have been wanting to smoke so bad, and I was given a huge amount of weed. I rolled like 15 joints that I am looking forward to smoking one of them when this is all through! I am hopeful that they do not do the swab today, but even if they do it will have been about 20 hours since I last smoked. I hope they like me and plan to do to the swab test later in the week. But I would’nt mind just doing the test today so I could be relieved and smoke again. Either way, I am an exotic dancer and need to find a normal job so I can quit dancing. I hope to avoid the weed as long as I can so I can get a real job soon.

      They won’t drug test you on your first interview. The first interview is a screen. They may have you take a drug test within a week of the first interview or just after/during the second interview. It works like that almost everywhere.

      • Ed

        Yes they do test you on the first interview. I went to 3 different factories in NC, each one tested me in the spot

  • curious

    So if a company says that do a 6 panel saliva swab is this more detailed or pretty much the same as what you are talking about here??

  • kelly

    • Anonymous

      If they already did a test on you and left with a positive test result, you’re boned. Maybe follow the terms of your case next time?

  • Ken

    What about a spit test going to a lab like they do a regular piss test

  • Missy Fuhrman

    i am an occasional smoker and i have swab test next thursday and i havent been smokeing since wednesday night will i be ok?

  • itsthatgirl

    P.S If you ask for a glass of water and they do not watch you, you can get the strip wet with water instead of saliva. Someone told me that.

  • lilsmokeY

    I have been clean for 56 hours. can I pass a test with out mouthwashing the day of?

  • DJ MWDuce

    i can only say that my wife smoked minutes before a swab test ( thought it was gonna be a urine test so had fake urine on her for the test) passed no problem. drank a cup of water before test and passed. the test can not reliably detect thc since it attaches to your fat cells and good luck on those in the mouth. so everyone calm down. if it is a sawb test thank god becauase ou wont be found out for once

  • gpman

    Is there any way that I can fail a mouth swab if I only took three hits 19 days before test

  • worried

    No news yet I think thats good right

  • Anxious

    I smoked about 5 days ago and just had to take a saliva test today to see if I have to get probation or not. Do you think I will pass?
