An alcohol test by ldetecting a specific BAC.

Test for weed doesn't hit on THC, the ingredient that makes you high.

It tests for THC-C which is what the enzyme the liver breaks THC during metabolation.

He's right about THC. It's looking for the metabolites. And it depends on whether they are using a rapid test which will determine if you've hit a certain cutoff level for it or not on the spot, or if they're using lab testing which is going to see if there's any at all. You aren't beating a lab spectrograph. And that metabolite can take months to get out of your system based on your body fat, metabolism, etc. If you're a big ole boy, it's going to be there longer.

As for alcohol, they can test that in urine as well and catch you drinking as far back as five days ago with an ETG test. Which can also be done as a rapid or at a lab.

If you want to beat a drug test, the only way you're going to be guaranteed is don't have it in your system. If they use a rapid test cup or dip card and you test positive, they're sending it to a lab for a forensic confirmation. So the idea that you can blow a test and then take it over the next day is EXTREMELY unlikely if it's for employment. They will seal that first one up, have you sign it, seal it in a bag, have you sign that, and then it goes to the lab and it's pretty much 100% bulletproof that if you failed it you're about to fail the lab test. Rapids only are wrong about 1% of the time. False positives are rarely proven.
