There is nothing that will "mask" the drug from the test... that is if the sample was not tamped with. While there are a number of products on the market whose manufacturers and distributors claim will flush your system, there is nothing that will do this either. Most of the products sold for this purpose can easily be detected as well, which can lead to a second charge of conspiracy to conceal.
In my experience nothing is full proof. Depending on the testing situation I try to carry in clean urine obtained from a friend but some places watch you pee and you have to have the temp between 90-100 give or take a few degrees. may also go with dilution but is a bad idea if the sample is going to be sent to a lab. It also causes your urine to be suspiciously clear. I will say that most of the detox products on the market are scams. Again there is no full proof way other than just being clean yourself.
It depends on what drug you are trying to hide. Some drugs (like cocaine) only stay in your system for a few days after you quit doing them. Other drugs (like marijuana) can stay in your system for up to a month if you are a heavy smoker. The best thing to do is to try and take a break for as long as possible before the test, as well as getting a cleanser. They should be available at most headshops - its a drink that you take the morning of the test to help clear you up!
And of course there is always the option of using someone else's urine, but personally I find that just too gross and not worth it :)
you cannot mask it

No. A tobacco test looks for.. well... tobacco. A marijuana drug test looks for THC.
It is hard to find a drug test that doesn't test for opiates. however my friend is joining the NAVY and he tells me that during his DET meetings they only test for amphetamines cocaine and marijuana. so to answer your question it is most likely probable that a drug test will test for opiates, marijuana cocaine and amphetamines
