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.

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.

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.

I have laughed reading some of the reviews about how parents should trust their kids. Well, I happen to be a parent with a kid who has proven to be very untrustworthy about certain things. We have rules- you fail a test, you lose priviliges. Driving is important enough to this kid that he has stopped the weed vapes. But it's only because of these tests. It was also really amazing how long the THC stayed in his system. No- I'm not naïve- he was practically under house arrest so didn't use anymore. I know the test says it doesn't matter how faint the second line is- it's a negative. But I did find, the longer the time since he had used weed, the darker that second line became. I figure these are like a reverse pregnancy test. LOL My son is finally testing with strong negatives but I have no illusions. If I hadn't been able to test for it- he would still be using weed vapes every chance he could. I also really like the nicotine and alcohol tests. I make them test first thing in the morning just like you would for a pregnancy test..it has worked really well. My kids who aren't into things they shouldn't be into don't mind testing because it further proves they are trustworthy and therefore get more freedom.

Test strips on Amazon Review This product and many like it used in doctors offices daily across the country and have an amazing amount of false positives and negatives. Physicians and employers know this. Hence typically used as the first line, fast indication of cannabis or other drug use (while you are in the office so you can pick up your monthly Rx) for chronic pain for example, it will be sent out to a lab for a much more extensive analysis with lower positive thresholds (20ng/ml vs. this product 50ng/ml), and conducted with advanced lab equipment that doesn’t give false positives or negatives. Your physician in this example is covering his a*# to ensure your compliant with your pain contract for litigious reasons, monitor any drugs or meds that could kill you and follow state and federal compliance laws. They want to make sure that you are taking the medications that they are prescribing and not diverting (selling it to anyone else). They will also include alcohol (which by the way has a 5 day detection time from last consumption) via the lab equipment mentioned below. The urine sample will be analyzed through a highly specific/sensitive lab equipment called Gas Chromatography (GC)/Mass Spectrometry (MS) which is 100% accurate. It actually measures even levels of cannabis, prescribed medications, alcohol, illicit drugs etc. and physicians know exactly what the levels should look like for the amount of medication they are giving you. They are looking for your compliance and not diversion, hoarding, or doctor shopping. Additionally, as previously mentioned, GS/MS have a much lower positive threshold for cannabis than urine sticks at 20ng/ml in urine vs. 50ng/ml for stick with THC metabolites specifically. The manufacturer claims a 99.9% sensitivity and specificity for THC. They are dead ass wrong! You will get false positives and negatives. I have researched this extensively and written about it for patient education in a national cannabis publication and teach medical professionals living in the state first to legalize cannabis. If your a pain patient trying to reduce your medication intake via use with cannabis, be sure before you do you discuss this prior with your physician. If you have cancer because of the other benefits like nausea and appetite suppression, they might allow it but you need an open and honest dialog before they start prescribing controlled pharmaceuticals. Esp. if you live in a strict state with either no medical or legal protections in place. If you breach your pain contract and are caught without a prior discussion at your first visit before you sign that contract, you will be dismissed from his/her practice and your chance of finding another creditable physician or psychiatrist (stimulants also schedule II drugs) is basically fruitless since they will want to see your previous prescribing physicians chart notes. This is esp. true in today’s political climate regarding the so called opioid epidemic. What the news doesn’t say is the majority of these deaths are the result of heroin, methadone, and benzodiazepines mixed many times with other illegal drugs. 28 people a day die nation wide. Vets. are often prescribed pain meds along with many other psychotropic drugs for PTSD or battle injuries for example. Sadly since they get their healthcare through the VA hospitals which are federal institutions that still believe cannabis has no medicinal value and scheduled I like other illegal drugs, you will likely loose your medical benefits so be vigilant. It’s sad, esp. with the promising research and anecdotal stories of so many veterans being helped by cannabis with crippling PTSD or other conditions. Similar would be various forms of severe epilepsy, esp. in children. Since pills are much harder and more expensive (than heroin for example) to get now vs. in the 90’s and 2000 due to unscrupulous Pharmaceutical companies promoting OxyContin for acute low back pain like Purdue Pharma (which is currently being sued by numerous states and have already paid the federal government over $600M in fines for off-label promotion), people are using the harder drugs that are much cheaper and easier to attain. That is the “opioid crisis” in America along with Methadone clinics and cheap Fentinal coming from China mixed typically with heroin killing people. Fentinal is 50 to 100% more potent than morphine hence people OD not knowing what they are injecting. Drug dealers mix it for a “better high” w/ heroin addicts to increase their margins and make opioid tolerant addicts get as high as possible. Given to an unsuspecting customer that is opioid naive (low tolerance) they have a cardio-respiratory failure and never wake up. Many celebrities are typically featured by media outlets when this happens but it could be anyone and crosses socioeconomic boundaries. The government also watches physicians prescribing (# of controlled substances they are writing vs. their peers in their specialty). If it’s too high, they get audited by DEA, loose their license and go to jail if their isn’t proper patient documentation. Guilty until proven innocent esp. if they are prescribing pain meds with benzodiazepines since they are typically mixed with alcohol and cannabis. All cardio respiratory depressants. Everything is monitored now through state wide controlled substances databases that any healthcare provider can access, nurses, physicians, your pharmacist, etc. They are always monitoring before your appt., while the script is being filled, etc. Additionally stay away from signing up for state wide medical cannabis databases. You never know how that I formation can be used against you until the federal government reschedules cannabis. esp. if you enjoy your 2nd amendment rights. The tax breaks in OR, CO, WA, CA, AK are not worth it. Disclaimers: This advice does not serve as medical advice or instructions, just a summary of many years of research and my own personal experience with these testing strips on Amazon or through your local drugstore. Always discuss your use of cannabis with your physician and be proactive vs reactive or you might find yourself in many of the scenarios mentioned above. Bottom line...save your money on these worthless testing strips. All they will do is give you either a false sense of security or create tremendous anxiety. Peace and good health!
