Because the test is so sensitive that it can detect the alcohol used in hand sanitizers, mouthwash, etc.
A urine test for alcohol can detect alcohol if the person used mouthwash containing alcohol, ate any food containing alcohol, inhaled alcohol, used a hand sanitizer containing alcohol, had an injection site sterilized with alcohol, used alcohol on an injury, etc.
A Propoxyphene test is used to detect Darvocet.
A mouth swab test or a saliva drug test is mainly used because it is cheaper than urine or blood tests. It can show if an individual has recently taken any type of drug, but they're not as complex as urine or blood tests. For example, if you have smoked marijuana recently - the mouth swab test can usually detect it for up to 4 or 5 days. If you smoke marijuana and have a urine test done, it can be detectable for up to 30 days if you are a frequent smoker.

A polygraph is used to help detect if someone is lying.
That entirely depends on the drug being tested for. Some drugs are metabolized very quickly and after a day or two are completely untraceable using normal tests. Some stay in your system longer. What drug are you interested in, would make the answer easier. Not doing drugs at all would also make this question irrelevant :)
The 80-hour alcohol test is also known as the ETG test. This test is used to detect any amount of consumed ethyl alcohol.
