If the drinking is recent, and if the test includes a screening for blood alcohol level, then you may fail. Different tests screen for different things. If what you use is NOT part of the test in any way, then what you use will not be detected.
Drinking denatured alcohol will cause you to fail two tests: an alcohol test and a sanity test. Denatured alcohol? Are you out of your MIND? The methanol in it WILL make you go blind. This is no hoax. This stuff will blind you, destroy your kidneys and ultimately kill you dead. For God's sake, man, if you are drinking denatured alcohol seek help right now.
No.
No, drinking wine the night before any sort of drug test will not interfere with it. A hair test allows the tester check for drug use over a very long period of time, the only way to mess up the test is to shave your head!
Alcohol will not change what is in your body besides it. A urine test may have slightly lower levels of THC metabolites than usual (since alcohol is a diuretic and you will lose water quicker, diluting it somewhat) but if you smoked marijuana, you will still fail any drug test regardless.
of course; its always a violation
You will not fail a DRUG test if you drink alcohol the night before. It's a DRUG TEST, which means they are testing for illegal sustances, not alcohol intake. But that doesnt mean to get excessively drunk the night before either, 3 or 4 drinks is ok.

No. Red wine vinegar contains no alcohol.
The cough syrups that could cause a drug test to fail require a prescription to purchase.
