so if I smoke Mary Jane in Amsterdamn (where it's legal) or Colorado, California, Vancover (where it's also legal) then they do a hair test - that's gotta be unconstitutional ! I could be loaded on oxy, zanax, alcohol, benzos, etc and that's OK but God Forbid you smoke a little weed. How f**ked up is this country and companies that test. Cocaine is out if your system in 2 days - Herion maybe 3 but pot stays in your system longer, so basically they are testing for pot.
