Easy@Home Marijuana Urine Drug Test Kit [15 Pack] - THC Tests for Home Use - Weed Detox Testing Kits with 50ng/ml Cutoff Level #EDTH-114

I was a forensic toxicologist for 20 years and have had friends and coworker ask me about testing for THC over the past few years since it has been legalized in many states for recreational use (including my state). I handled R&D for SAMHSA/NIDA confirmatory testing by GC/MS, as well as initial screening by immunoassay using various instruments (Hitachi, Olympus, etc). Since these were FDA approved and to SAMHSA standards, they would more than likely perform as expected. In order to recommend quick test strip kits to people, I decided to try some kits. This product performed well in my testing. I used myself as a negative control and the expiration of the strips I received were in 2019. The result was correct with the THC patient line being the same density/color as the control. I then tested a known user at two stages. They were a light user so I tested 1 hour after use and the test was as expected, with a slight positive (faint line on the THC but less prominent than the control). At 1 hour I expected it to be either negative or slightly positive due to the cannabis metabolism rate (but it can vary depending on the individual). I also tested after about 8 hours and it was positive with no THC line and the control line was valid. I have read reviews that say their test did not match the result when sent in to a drug lab and I would warn people that this can be due to many factors and most do not relate to the strips. The ones which could be strip related are expiration, faulty storage, faulty manufacturing (it can happen with any lab test, including reagent based). The most likely cause, however, is that this is a urine test. Urine tests are notorious for being dependent on the concentration of the urine. If you test on a dilute urine and it is negative but then test on a more concentrated urine and it is positive, this is not an invalid result. The same goes for a concentrated urine coming up positive and another test being more dilute coming up negative. If you want to match test results, you would need to do blood tests or check specific gravity or creatinine levels for a THC/Creat ratio. Also you are comparing two different tests. One is based on a test strip and the other is based on an analyzer that used reagents and much better immunoassay techniques. With a strip (as in thin layer chromatography), the result is dependent on the person performing the test being able to distinguish colors and bands, variations in intensity/density, etc. These are also qualitative assays and a 50ng/mL cutoff will vary greatly above that limit. You may not be able to detect even over 100ng/mL by eyesight. Analyzers in a lab use photometers for detection. From what I have seen, I would place these up with any other well made test strip. I would just be sure to return any you get that are close to expiration, which will greatly deteriorate results and more than likely make them invalid. These would be of most use for testing kids or others where you want to know if they have been using cannabis as long as you know to use a concentrated urine (first void after waking works well). I would not use them during a period of fluid intake because that would defeat the purpose. You could also use this to get a ballpark figure of THC levels by serial diluting the urine and testing each dilution to see when it comes up negative. There is no way to know the actual level but if it takes many dilutions (like 1:20) you can be sure the level is fairly high and will take much longer to clear, even on a concentrated sample.

Much better than the other brands I’ve tried. Other brands will have me “negative” within days after I’ve been smoking daily for MONTHS. This one shows progress every week on how close you are getting to a fully solid negative line. And this brand is also affordable, and easy to use.

Work exactly as they should. A note on the negative confirmation line: while even a faint line is considered by this test to be a "pass," it definitely scales with the level of cannabinoid metabolites in your system. While trying to detox my body, I tested daily and the line got darker and darker each day after it showed up. Why this is important: if you are required to take a more-sensitive test, you may still test positive on *that* test. I have been able to take two hits off of a whole bud vaporizer in a 36 hour period and still pass, though the line got fainter after the second hit. Further testing showed that it I waited 24 hours between hits, I could keep the line fairly visible. I have a low BMI and stay wrll-hydrated, which should help. As a bonus, keeping your intake low means your tolerance stays low and that one hit will keep me medicated for ADHD for almost 12 hours.

My boyfriend and I got these because we had to pass a drug test for a job. He hadn't smoked in months, and I hadn't smoked in a week. Using the test was incredibly easy and fast - it only takes 5 minutes for your results to show! The first time I took the test, I tested positive, which I expected, and the results were very clear. However when my boyfriend took it, he tested negative but the second bar that indicates it's negative was very faded so it was confusing for him. He followed the directions and checked the test after 5 minutes as instructed, and even checked again minutes later, and that second indicator was still very faded. We assumed it still meant negative because on my positive test the second bar didn't show up at all. On the day of my test, after chugging a calculated mix of creative, sugar, and b12, I tested negative on this test, except like my boyfriend the indicator for the negative was very faded and only looked like half a bar. This was very confusing for me, but I assumed it meant negative because when I tested positive I couldn't see the second bar at all. We both ended up passing our drug tests! So we're not sure if this test was faulty in displaying the negative results, or if it maybe traced very slight amount of THC in our system and that's why the negative indicator wasn't as clear as the positive one. So we assumed the test for ourselves looked negative, and we did end up testing negative, so I guess the products does work well, but I wish we could've gotten tests that had clearer results so we wouldn't have worried so much about how our actual drug tests would turn out. Also this is a GREAT deal for 10 drug tests. They're usually way more expensive in store.

The test kit is very easy to use and much less expensive than professional testing, but the results can be difficult to read. I used the test to analyze my results and, once those results were negative – I verified the negative results with a professional lab test. In my case, after leaving my previous job I vacationed outside the US for 6 weeks and smoked high quality marijuana daily for the entire time. THC level was probably in the upper teens and I smoked between one to two grams daily. Upon returning to the states I started my self-detox, and did not smoke ANY marijuana. With local labs charging $100 per test, I ordered these self-testing kits to determine my own results before spending the money for a lab test. I assumed the THC would clear my system in about one month, and was very surprised at how long it remained detectable. Day 37 of being completely weed-free: Started testing, got Positive test result. Not surprised, but disappointed. Day 40: Positive Day 42: Positive Day 44: Positive At this point I wondered if the test was accurate and asked a friend (who has never smoked) to take the test. The resulting bold line was clearly and obviously negative. The test strips were accurate. Day 50: Positive: Day 56: NEGATIVE. Very faint line, it was hard to be certain it was negative. Day 57: Positive. Not even a faint line Day 58: NEGATIVE. Very faint line Day 59: NEGATIVE. Line was clearly evident Day 60: NEGATIVE. Very faint line Day 61: NEGATIVE. With 4 consecutive negatives I paid for professional lab testing, and received a NEGATIVE result Day 68: I had an employment screen, and the results were NEGATIVE I am very happy with how this test kit prepared me for my employment screen. It is possible that some of my positive results could have been interpreted as negative, and allowed me to take my employment screen sooner, but for my peace of mind I would rather be safe than sorry. If you just assume the THC will clear your system in a few weeks, you will probably fail your employment screen. I think this test kit is very helpful for people that want an economical method to check their system for THC. However, I think it you should also verify the results with a professional lab before an employment screen. The negative results shown on the test strip are difficult to read, and if you mistakenly read the results as negative you could face the consequences of a failed employment screen.

I passed my Federal Drug test - I was using CBD with trace amounts of THC for about 6 months but with Federal jobs, NO THC can be detected in drug test. Purchased 2 boxes & came up hot for 3 weeks (I was almost thinking they didn't work)... and now the 2nd line is appearing. ABSOLUTELY recommend.

100% Saved my sanity. So, long-story short: I passed my LabCorp drug test with a 50ml/Ng limit after 4 days of abstaining and detoxing. These strips were a God-send. Long Story Long: I’m a casual smoker (one bol everyother day) and was recently laid-off. After doing a few interviews, I finally landed an offer. However, the surprise was that I had to take a drug test within two business days. Thankfully, the offer came on a Thursday morning, so I had 4 days to do whatever I needed to, to prepare. I’m not going to fool you, I was freaking out all the way up until I received the results. But the test strips at least gave me confidence. I digress though. After purchasing some 14 Day Cleanser pills from GNC, I 1-Day Primed these test strips. Again, I’m a casual smoker with a fast metabolism that doesn’t work out (~175lbs). Once I received the THC strips (50ml/Ng cutoff), I immediately tested myself. Got a very faint-red line. This was good considering it just needs to be faint. However, still put my intestines through the ringer with the detox pills, lots of water and healthy food. Because I was freaking out, I tested myself every 5 hours basically. I highly recommend getting a lot of strips (15+ packets). Over the weekend, the line progressively became consistently darker. However! The tests that made me really nervous were the first-in-the-morning ones, where the line was the lightest. Duh. This is the most corrupted urine you have, but if you see a line with that, you should feel pretty good about yourself. Day-of the test, I drank the Detox Cleanser drink to “mask” any remnant toxins, although I had been pretty confident in my THC cleanliness. My main concern is if the company that was testing me was going to go as low as 20ml/Ng on the exam. In hindsight, I would have ordered both level strips. All this being said, the detox drink makes you piss like a horse. My first pee after the drink (20 min before test) tested my best dark-line yet. Thankfully, I was able to smuggle-in a test strip into the test with me and tested the sample before giving it to the lab attendant. (Result pictures) The line came out slightly less dark than the pee after the drink, but better than my previous weekend tests. Always remember to catch the pee mid-stream, don’t over dilute with water before your test, and don’t drink alcohol leading-up to the official test. The picture shows the strip I used on my LabCorp sample.

Work really great to let you know you are positive, not as clear to read when negative. Faint line means negative, yet, hard to read whether negative enough to take laboratory test. Good value for price. Nice to have ample to test daily after detox.
