Blood Drug Testing

Do at home drug tests for marijuana really work?

If so, which ones are the ones to buy. Are the cheap ones you can get at walgreens as effective for detecting marijuana as the ones that you do at a lab for a urine test like for a job or something?

1. The over the counter drug test kits that you can buy are very effective. The same chemicals are used that would be used in a laboratory test.
2. Absolutely! You can purchase "Reditest" self contained specimen cups as well as panel dips. They are more accurate that most machine tests due to the super low minimum concentration value. They're very easy to read, like a pregnancy test, and even have a "control" that will let you know if the test is valid or not. They are available at Walgreens in many states. You can even send in the specimen to our home location for more specific tests. You can see how concentrated the specimen is, which would help you determine how much your suspected person[s] are intaking. For the "dip" style test, AMP, M-AMP, BAR, BUP, BZO, COC, MDMA, MTD, OPI, OXY, PCP, TCA and THC. For the Self Contained "Cup" : AMP, M-AMP, BAR, BZO, COC, MDMA, MTD, OPI, OXY, PCP, TCA, and THC.
