Instant Marijuana Test Kits, 99% Accuracy level, Easy to use. (100)

I purchased these for home usage, to track my progress while detoxing for a test. Purchased two packs actually, assuming I just needed to keep testing until I popped clean. When I hit 70 days+ with these still showing dirty, I became concerned and went to a lab testing facility in my town to get a quantitative test done for my own use. The lab test I paid for tracks all the way to zero, so gives you a pretty definitive answer. Waited a week, still taking dip tests with these, and when my lab results came back— surprise! I tested at 7ng/mm— FAR beneath the supposed 50ng/mm levels that these little tests allegedly provide. I suppose the one bright side is that it’s certainly better to show false positives than false negatives, but at the same time, I’ve been through about thirty of these, in two separate orders/batches, and EVERY SINGLE ONE showed as positive, even after I was unquestionably negative. DO NOT PURCHASE— SAVE YOUR MONEY, OR BUY ANOTHER BRAND. What an absolute waste.

I have been using this test and have gone through a testing facility to verify it is correct. I bought another type to cross check as i always test multiple times to be sure and with different companies. The other test showed clean and this test didn't the next day it was a very faint line showing clean. I would prefer a more definitive test result than even a faint line. For me it would be simple pass or no pass. Im color blind and really struggle with the color.

I left a bad review before I realized I was using the test strip wrong.To use:1. urinate in a cup a very tiny amount. enough that you can prop the stick in and get the paper tab wet but NOT the plastic part of the stick.2. let it sit in the cup and in a few minutes you have your results!Really works.I tested it on my friend who stopped smoking for some time but needed to know if they were in the clear. They came out negative. Then to make sure the strips worked, tested it on a friend who has not quit smoking and it came out positive.

I needed to test clean for an exam, so I purchased these tests after reading the reviews. I gave them 5 stars because my exam results and the results of these tests were congruent. The one thing that bothered me about these tests is that the negative line can be very faint, to the point of you questioning whether or not there's an actual line there. Given my experience with these tests and how easy they were to use, I would highly recommend them.

Was smoking heavy. Quit 31 days ago and tested myself this evening out of curiosity.I'm not overweight and I have a fast metabolism. (5' 8"/150 lbs.)I did not flush my system with water beforehand.Just giving you toker's out there a heads up.Peace & Love! Peace & Love!

They’re accurate. I was dirty and it told me so. Verified.

This product worked great. The school my daughter goes to started drug testing so, I ordered these to test my daughter to be on the safe side. I tested someone that I knew would be positive and it tested positive and then tested someone that was negative and it tested negative. The product works like it says. I would buy again.

cheap kits, work great for self-assurnace
