What tissues or fluids are used to examination for the presence of drugs?
As for fluids: urine, blood, sweat and saliva. In that order. But, in the past checking sweat or saliva (very uncommon) they would take coat samples and interview the follicle. That test will show drug use from waaay wager on. As for tissues, I don't think they ever shift that route, unless you are a corpse!
blood... if you are talking just about narcotics.
Blood, urine or even hair can be used to exam for drugs.
