yes...there are nicotine tests that work somewhat like urinary drug tests. They can detect nicotine in your urine.
I was curious of the same thing. Studies show, it should be out of your system in about 3 or 4 days with lots of water, if you only smoked once.
If you smoked marijuana, very likely not, but you never know. Other drugs i am not sure about
you can't.
Depends on how long since your last toke. If you smoked 3 days before a drugtest, then you will most likely test positive if you don't plan on cheating.
If you are looking for a midnight job in Mancan, but smoked weed in the last ten days, you should be aware that it can take up to 30 days for the drug to leave your system in order for you to pass the test.
marijuana stays in your system typically 3-30 days depending on how frequently you smoke and the potency. if the last time you smoked was 45 days ago, then yes you should be fine
no
It usually isn't tested in such a way as to determine how long ago it was smoked. It could be narrowed down to within a few days if there was a need to do so.
No.
Yes.
If you smoked marijuana for a month - then no, you cannot test clean in two days no matter what you try to do.
Yes, you can .. a saliva test is designed for a maximum window of 3-4 days
