Yes they do. I have first hand experience with this (11-28-2011). I was offered the finance internship in Cincinnati, Ohio and it is their standard protocol to hair test all new employees. I failed it due to trace amounts of THC in my hair follicles (I had not smoked in two months), and they rescinded the offer. If you are applying there quit smoking for at least 3 months, as this allows the THC enough time to cycle out of your system. However, if you are doing any other drugs i.e. coke, molly, meth, or heroine, get your f**king sh*t together and quit being a worthless loser.
