Easy@Home 15 Pack Marijuana Drug Test Kit - Urine THC Test for Home Use

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.

Very easy to use test. I’ve been a heavy user for years, daily consumption, and completely quit a little over 2 weeks ago. Which I like, btw, I feel better and mentally much clearer, I also have a lot more energy . I also started working out again when I quit, so that helps as well. I bought 20 of these test strips. I have a job interview coming up in a week, and they will drug test me, most likely a urine test. I run a test every other day, just to see where I am at. I still very clearly test positive, which is to be expected. I hydrate well. I am aware that it might take weeks, maybe even months to get the THC out of my system. The test is very easy to handle, just follow the instructions. I store it as recommended (in my guest bathroom, which has no window and is at a constant temperature of 73F). I recommend this test, and hope that I will see negative results soon.

These worked great for my pre-employment. I don’t partake and teach she very often that’s why I bought them just to be sure I would be negative, but I had my partner test as well to make sure they worked because I knew he would be positive and it was accurate for him and I and I passed my pre-employment screening and good to go. I say they are very accurate and if you are anxious like me, definitely give these a go on top of any other drug test you purchase.

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.

I’ve checked countless drug stores, and many of them are charging an outrageous $24 for a single test. No thanks! These work great and are a much better value. I’m using them while detoxing before a drug test, and it’s been really helpful to see my progress each day the test line keeps getting darker, which gives me confidence that I’m heading in the right direction. Definitely recommend!

Amazing product 💯 accurate if you have the slightest 2 lines on this test it’s negative I took this and I have gotten positive the first few weeks. I’m a very heavy user who smokes several daily so was worried if I would fail this test, but I took the test at quest for my employment and it was accurate and I got negative results! If you’re feeling worried if this won’t work they will…at least for me and all the other reviews I agree that even the slightest 2nd line means it’s negative! The darkness does not specify how low it is below the 50ng cutoff. I completely recommend this brand for a fast reliable test. Just make sure you do it in second void first void is highest concentration so I recommend waiting for the second or third void as long as it’s pale yellow and not clear

Very accurate would recommend if you want to check at home! I would say they are pretty accurate because I tested myself over the span of a few days and as the THC left my body the double lines were more darker and at first they were very light. Good price for the quantity of test strips.

I had taken Delta 8 THC gummies a few times over a month period-I'm not a frequent user. I got a job requiring a drug test and had 2 weeks to detox beforehand. Unfortunately, edibles stay in your system longer. And even though Delta 8 gummies are legal in my state...there is no way to distinguish on a drug test. The job had a no exceptions policy unless it was prescribed. So, I purchased these and used them over the 2-week period before the test. At first, I was testing positive (absolutely no visible line). Eventually, it was hit and miss depending how hydrated I was and definitely positive in the morning before hydrating. I can say the line indicating you are negative is never as vivid as the control line. That made me continue to be stressed. I compared to the Walgreens cup test and similar results. Anyway, I passed the drug test. Recently, I found an extra test and took it because I haven't used drugs in 4.5 months. It was negative but the line still wasn't vivid. I guess that is just the way the test is. So, if you see any line at all no matter how faint, I think you should feel confident you are negative.
