no.
That really depends on the energy drink and its ingredients. Under normal circumstances - no. The most commonly available energy drinks do not contain ingredients that would make you fail a drugs test. Be aware though that some energy drinks contain the ingredient "niacin" which in itself will not make you fail the test but is used as a masking agent for drugs by offenders. So sonsuming an energy drink containing niacin could in theory get you under close scrutiny after a drugs test.
No.
No, energy drinks have no effect on pregnancy tests.
Without a doubt, YES!
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.
You don't. Energy drinks contains ingredients that are known to cause certain effects in humans and energy drinks make their claims based on the effects of those chemicals. If there were a way to quantify, numerically measure, the actual added "energy", most of these so-called energy drink companies would go out of business for selling a lie.
If they're testing for alcohol and you come to the test drunk, or if it's an EtG test and you drank within four days of taking it, then yes. But if it's a pot test or a cocaine test, it won't show up. They test for specific drugs, not just "every drug anyone's ever gotten high on."
can i get a false positive test for k2 from drinkin monster energy drinks
No. Amphetamines are controlled substances and can only be distributed with a prescription from a doctor. It has been known in other countries with different laws, that amphetamines are contained within energy drinks. An example country which I know this is true, is Thailand.
You can't. There are many test that an audiologist will perform in which you cannot fail intentionally. You might be able to fail some of the test, but there are many test in which it is impossible to do so.
Everybody is different so for some energy drinks help the brain wake up. In other cases it energizes the person to much that they can't concentrate. I personally cannot focus after drinking an energy drink as I feel hyper.
