Just a word of caution to everyone here on RIU. I am getting ready to take a medical exam, that includes a drug test. I quit smoking THC a few months ago, but I continued to use Kratom 1-2 times a week because it's not a drug and isn't supposed to show up on a drug test. I bought a First Check home drug test and just got some results. If a line appears, it's a negative for that drug. No line is a positive. The line for meth in faint, but it is there. I don't use meth, or any illegal drug for that matter. The test gave a positive for Methadone which I don't take and TCA (antidepressants) which I do take. These home tests will never be 100% accurate, but something gave this one a false positive for Methadone. I used Kratom Friday and Saturday, so I am assuming it must be that. I guess I'll have to quit using Kratom and wait another week or two for my exam.
