Does the drug K2 show up on a hair follicle test? How far back to those tests go?
If someone smoked K2 and they have to take a hair follicle test will it show up on the test? Yes I know that K2 is legal but I need to know if it will show up as marijuana on a test?? And if someone smoked marijuana 3 years ago will that show up on the hair follicle test? Any external links and use of sources would help greatly! Thanks
