Question by Marcie L: Hair drug testing – can a lab tell the different between ritalin and street drug with meth in it?
If you take methylphenidate for adhd and you also took street drug speed and you are drug tested by them taking your hair, can a lab tell the different if it was from the ritalin or street drugs with meth in it? Also can they tell the different if you took meth/speed and a vicks inhaler?

yes, a lab has the ability to take the drugs apart by chemical compound. they run a general test that will show you positive for the amphetamine, then they run further tests. Meth has different chemical compounds. They would not test for the Vick’s inhaler.
