No.
No, it should not affect this test.
Not at all no worries. But it can and will in a blood test of any sort.
No it absolutly will NOT affect a breath test, If you want to be sure for yourself you can buy Breathalyzer at Zellers and they are not that expensive. NyQuil absolutely won't make you fail a Breathalyzer.
No it doesn't appear that it does from any research on the Internet.
If you haven't eaten for a period of time will it give a false positive reading on a breathalizer test
No, or else there would be a bunch of drunks on the road popping penicillian.
Yes, in most states the breathalyzer is seen as a presumptive test.
Theoretically it is possible that flavoring agents might affect the outcome of the test - that is why subjects being given the test are instructed not to use mouthwash or chew gum prior to their being administrered the test. HOWEVER- if you are thinking of using that excuse as a defense consider this, the option to a breathalyzer test is the blood alcohol test where they draw blood at a medical facility in lieu of the breathalyzer.
There are several services that provide breathalyzer tests. You can install a test in your teen's car but there is no guarantee they will use it.
Yeah
