Wow - this is incredible. This probably isn't the proper forum, but I had no idea you could tell med usage by hair samples. I guess I'm really behind the times. Amazing.

I'm really curious. What do they do - just cut off a snip of hair and analyze it? If this is so easy (I'm not being sarcastic or anything like that, just curious), why don't doctors and hospitals just analyze a piece of hair instead of taking urine samples or blood screens or other tests which make people uncomfortable. Surely if meds can be detected this way, some diseases could be too? I know I hate blood tests - they make me very dizzy and sick to my stomach. A snip of hair would be nothing. This would seem to be a great diagnostic tool and spare the patient from more invasive tests.
