Are you meaning a forehead drug test that you would place on your forehead and it test the sweat or something that has to do with your skin? If so I think that it is the same as a mouth swab 3 d+ays but as I firmly believe those kind of test are not accurate. I had to take a mouth swab drug test for cps and I failed it with cocaine and I have never done cocaine in my life and I should have failed it with opiates because I was taking prescpription hydrocodones and I didnt. I have had many other mistakes with drug test even the ones that are sent to the lab through probation. So like I said I firmly believe that those test are inaccurate. But I believe that they are only supposed to go back 3 days.
I assume you don't want her to know, or you'd simply ask her. The easiest way to secretly drug test someone would be to get a sample of her hair, and submit it for testing. Hair follicle testing is not as reliable as blood or urine testing, but goes farther back in time. The length of the hair determines how far back you can test.

NO... this is not true! The furthest back a drug test can go is about 6 moths if they use a sample of your hair. Urine drug test can only go back as far as a month.
9 months
No. If you are over the cut off on the drug screen, it doesn't matter how far over you are. Failing a drug screen is failing a drug screen.
as far as i know when a person is tested for drugs they are not testing for the actual drug itself,but for the anti-bodies that fight off that certain drug.
it will only detect MAX 72 hrs
atleast 6 months to a year
5 years
The first drug stores were established in 754 in Baghdad.
If you can bend that far. Sure.
When they do hair follicle testing, they can see your drug history. Which means they can go back as far as your length of hair will allow them and it usually takes about a week for what ever it is that you used to grow out into your hair, and unfortunately there is nothing you can really do about it.
