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 have a oral drug test Tuesday at 1030am last time I smoked was at 530am Saturday morning (today). I have been brushing my teeth tongue and gums all day today. Plan on doing it tomorrow Monday and Tuesday morning before the test. If I do all that and don’t smoke all weekend do y’all think I’d pass on Tuesday morning??

  • VictarionGreyjoy

    ok now ive read so many post below and I basically get the idea…. although one difference I will have is I have bottom dentures and a top partial with only one real tooth holding it in place….. so I mean im thinking the answers pretty obvious, but is there anything else I should possibly need to know??? I have no swab test scheduled as of yet (my buddy told me it takes 15 days and this site says 24 hrs….. then my female friend whom has 3 degrees told me 24 hours as well) ….. IDK im just nervous because I just lost the most important person in my life and I truelly didn’t wanna become an alcoholic after drinking myself to sleep the first 2 nights afterwards so I had to buy a cut of pot last night…. if im rambling Im sorry cuz I probably don’t even know because im still a train wreck but I need this job like yesterday because my family is stuck with so many property taxes and things of that nature….

  • sabastian

    Hey i ive been smoking for 10+ years heavily (8th every 2 days) and i had a swab test just this morning and passed. I quit for 4 days brushing heavily and using regular listerine. I rinsed with hydrogen peroxide and listerine before the test then munched on about 10 altoids. This test is a peice of cake! Still was so goddamn nervous tho

  • prettyredstoner

    Hey guys! I smoked on Sunday/Monday maybe around (12/1 am) .. I am taking a college course in which we had to take a drug test (I didnt know). It was today! The oral swab. I rushed out the house and forgot to brush my teeth smh but I’ve brushed themof ccourse since sunday and I smoked a cigarette yesterday. Pf course been eating and drinking regularly. What are my passing chances? btw im a rookie smoker so its mid most of the time and I always tap and put out. I’d say this week I’ve only smoked 2 1/2 whole blunts!

    Also let me add that I was told to keep it in 5 minutes between my teeth and inner cheek. I did not. I had it in my mouth so it barely touched anythibg in my mouth!

    • somerandomperson

      Actually 3 weeks ago my friend smoked 9 1/2 hours before her shift and didn’t listerine or brush she just rinsed her mouth with her water and passed so it might be a good chance but you never know.

      • Jason

        finally somebody who has the answer to our question

  • teatea

    I have to get my mouth swab but it the type of swab that they take back to the lab! So how do I beat it????

  • Vicious

    I had a mouth swab pre-employment drug screening yesterday. I smoked the day before, the last BH being around 11:30pm. At around 1am I drank 1 bottle of the super concentrated stip nc that covers blood, urine and saliva, also brushed teeth before going to sleep. I woke up at 6:30am, ate breakfast and drank another bottle. Then proceeded to brush my teeth again and using mouthwash up until my interview. Hydrating as well. Now my question is, are the chances of me passing the test good or not? Please help. Thanks

  • Wendi

    Does anyone know what kind of testing places offer a swab test opposed to a urine test? I want to get a swab test and was planning to go to a labcorp but need to find out if there’s a better place to go. Please and thank you

  • Sabrina

    So I hit the blunt once last night around eh 11:00 & I brushed my tee that night brushed them in the morning and then went to work around 4 got told I got selected for random drug testing with mouth swab.. & I ended up taking the test around 5 pm. Right before I ran in the restroom and all I had in my purse was toothpaste and chloraseptic. I sprayed chloraseptic all over the inside of my mouth then squeezed toothpaste in there and swished it around and threw some more toothpaste in my mouth… Wondering how clear I will be lol. Help.

  • hollar

    So I smoked a few bowls the day before and then I hit it a few times before work around 550 went to work and had to take a drug test at around 1 I smoked cigs and rubbe Tabaco all over my gums and used a lot of mouth wash and bushed my teeth a lot to the point my gums were bleeding and drank some water and sucked on altoids and had one in my mouth while I took the test should I be okay?

  • Gonzo

    Smoked at 1AM and have a test 13hours later. SWIM smokes frequently(about a Quad-Half Oz. a week of some good herb) and SWIM is brushing and mouth washing as much as possible as well as rinsing with hydrogen peroxide because SWIM’s heard that helps as well. Anyone thinking my odds are good? PS. It’s an oral swab that is likely to be sent to a lab… Feel free to comment ASAP

    Okay this is a true story I smoked on a Thursday morning between 10 and 11 AM then was told around 3 PM I had to take a drug test the next morning at 9 AM I bought Listerine mouthwash peroxide and Altoid it’s the mini ones I brush my teeth three times that day I am rinse my mouth with while mouthwash and peroxide the next morning I brushed my teeth rinse my mouth with mouthwash and peroxide chewed on a couple of many Altoid and took my oral swab test and passed it!!!! It’s completely possible to pass THC is only detected within 12 to 24 hours after smoking

  • JorgeLopeStems

    Does it make a difference when oral swabs are sent out to a lab for the results?

  • JorgeLopeStems

    Just wanted to thank everyone who posted helpful tips and calming stories through anxious moments. I passed !! Got the best job ever thanks to all of you !! =0) On my way to Celebrate all night, than I go in at noon tomorrow. Amazing!! Special thanks to #peachdabs

    • Chris

      Did you do anything specific ?

      • JorgeLopeStems

        I pretty much read everything I could first. Than I mixed and matched a few suggestions. I really wanted the job so I didn’t do anything that seemed like it could have an unpredictable outcome. For example scrubbing the gums till they bleed. I’m a heavy smoker for the last 10+ years. Never had to stop smoking until just now. According to some journals, and other postings here I think 4 days is the furthest a saliva based screen goes. So I stopped smoking 6 days Prior to going in for the screen. Within those 6 days, I brushed 4 times a day and worked out every day, ate healthy and drastically increased how much water I consumed daily. Past that the day of the exam I woke up brushed 4 times and used Scope after every brush. On my way to the exam I had a pocket sized bottle of antiseptic Listerine and a small tin of Altoids. Chewed about 3/4 of the mints on my way there and then used the entire Listerine bottle near the facility. Once inside I kept a handful of mints in my gums up until I was just about to put the swab thing in my mouth. Fortunately no one was watching me, and I administered the exam in private; therefore it let me hold the cotton in between my teeth. I tried my best to make sure my cheek nor my tongue were really in the way or touching it. It took about 10 minutes for the dot to turn blue and once it did they send it off to a lab. I waited 3 days, and got the call that everything came back clear. I was good to go. So the exam is def. made not to fail. My girlfriend and I both have anxiety, lol unfortunately so we can smoke about 2-3 blunts daily, or sometimes just a blunt or two at night. That has been pretty consistent for the last 5 years, and before meeting her I smoked the same alone for an additional 10 years. SO obviously am a chronic smoker. I am 5/9 and weigh about 180lbs if that helps draw a metabolic comparable. Good Luck.

        • Chris

          Thank you this does help so much

          • JorgeLopeStems

  • taytora

    Can I fail a mouth swab test just from rolling blunts not smoking

  • Karlynn Beechner

    How long is weed in your stystem

  • Karlynn Beechner

    My bf is going for a drug test tomarrow and wants to smoke but is afraid to test negtitive he’s on probation so if there are any tips that can help me I really would appcraite it

  • ILike2Fish727

    Here’s my story. I’m a daily smoker – about 2-3 bowls per day of the best I can get. Generally it’s the name brand weed – Sour diesel, Girl Scout Cookies, etc. I am 6’0, 200lbs and work out daily with weights and cardio. I took a piss test about 2 years ago and was able to pass it after 3 1/2 weeks of not smoking using all the normal methods – lots of water, exercise, using mid-stream piss, not taking the test first thing in the morning, etc.
    Now im facing a mouth swab saliva drug test for a new job. Today is 9/23. The last time I smoked was on 9/10. Since then ive been working out, hitting the steam room, drinking water, etc. Just for the heck of it I bought an at home piss test and used my very first pee of the morning just to see what was coming out. I failed it.
    Everything I’ve read on the internet says that saliva mouth swab tests don’t go back as far as piss tests but since I was a daily smoker of good bud, I’m still concerned….Especially since failing the at home test. My mouth swab test is on Thursday 9/25 and at that point I’ll be 15 days clean. I plan on doing everything I’ve read – fatty meals the day before and day of, brushing really well my teeth and cheek, using Listerine and Peroxide rinses, and some altoids right before.
    The test is administered at the location and then sent off to a lab.
    I can’t ever recall being this nervous for a test before…probably bc if I fail I will lose out on a 6-figure job which is total bs. I’ve smoked for awhile and excelled in everything I’ve done – even won salesperson of the year last year out of 40+ people.
    Any other advice from anyone? I will certainly post my results as I’ve become frustrated with reading a lot of people’s stories without seeing them post a result.

    • krazie

      I smoked saturday nigh /sunday morning took a swab test monday and i passed u s j ould be good

      • ILikeTiFish727

        I took the test. It was an Intercept mouth swab. I chewed altoids and ice right before the test. Swabbed it up real good with that first bit of (still cold) spit and then kept it between my teeth. Praying that I pass.

        On another note, I found this on Linked In. Note the people commenting:

        • ILikeToFish

          I passed!! Glad this site and others exist. You can find a lot of information by looking at the manufacturer’s websites that make these products. -ILikeToFish727

  • kelsie

    Ive smoked everyday for 6 years and at least 3 times a day. I havent smoked in 9 weeks and I have a urine test next monday. will I pass?

    • ResearchIt

      Yes, thc is only detectable within 4 weeks after use through conventional means. Hair folic tests will detect more but are seldom used.

    • christina

      for sure keep drinking water :)

    • case2101

      Im sure you’ll pass. 9 weeks is plenty of time. Ive been a heavy smoker too along with all my friends. 9 weeks? Damn I’ve had it out of my system in a week. If ur really worried Bout it. Drink a lot of water, and tea. Whatever you can do to piss a lot daily. But I’d bet you’ll be fine. But a piss test I’d give it a week or two. These saliva test a day or two. I wouldn’t even worry about it. You’ll be fine.

  • cookdbug

    I smoked a bowl at 8am and had a saliva test at 9:30am. (I did not know this was going to happen)I passed! I had not brushed my teeth just 1 tic tac. I smoke all day every day for the last 3 years. I don’t think these tests are very reliable…LMAO

    • Neewk Rehtse

  • chris spotz

    Took a swab test this morning, after I woke up at 5am and hit a jay around 6am before going to the interview. I brushed my teeth, used peroxide, mouthwash before I left the house. Didn’t take the test till 10am, 4 hours past since I last smoke. Hopefully I pass! Also I used mouth wash and peroxide a second time right before taking the test in the car and smoked a cigarette. Anybody here gone through that and passed???

  • Sue Dashiell

    Have a swab on Monday,, smoke daily for 25 + years, this is new to me. I am a older woman who enjoys the pleasure and its a huge pain reliever for my chronic pain in all my joints, I desperately need this job…. Any help is appreciated, nervous and need this job.

    • Mary Jonesinton

      Don’t smoke this weekend if you can. If you have to for your pain and have no other choice use an edible or something you can swallow without much chewing.

      Try not to use anything the day before or at minimum day of test. Make sure to brush well and use mouth wash. The more you wash the better. If possible mouth wash before the test.

      But try not to make it to obvious.

      As long as its a true saliva test you should be OK. The metabolites don’t stay in saliva more than 6-12 hr. But if they test ur checks it could be a problem. But, most of the time you should be OK.

      There are products that are used to pass saliva test. If that is a regular form of testing at you work place you should look into picking up a bottle or two.

      I have use one before and they work, a friend that didn’t lost his job, but that was over 10yrs ago. My current employer does urine tests on a “as needed” bases. Which means I have to look at the ground when talking to management.

      Good luck, check out my blog if you want. I kind of made helping people deal with this my thing.

      And can you reply to me here afterwards, I pray for good news
