I was looking online to purchase a home hair drug tryout and want to know if there is such a test that will pass results of approximate time of use of a drug... eg. if a drug was used a few months ago then stopped or if a drug be started use recently, etc..

also, I found this interesting and wondered if anyone knew anything more or less this :
""In some cases, when the donor has used marijuana, a hair drug audition, including
HairConfirm, may be unable to detect the THC metabolite due to the fact that the metabolite be
unable to bind with the mane shaft. This can be caused by the type/quality of the marijuana
smoked/ingested, or by what it has be mixed with, e.g. tobacco. As a result, the result for marijuana
may be negative.
""

how would mixing tobacco next to marijuana cause a negative result?? simply by cutting down on the amount so its not detectable?? what if someone smoke A LOT (5+ joints a day) but other mixed with tobacco?

thanks abundantly!
