I think I read somewhere that they can do the same with a fingernail sample if you dont have any hair. Im not sure if this is correct, I need verification.t0k3r420 said:lmfao well if the cops are infact desperate then they can test ur hair so..there is no way to change that except shave ur hair
well its contreversial to everyone how to pass a dam ua, heres some things i heard:
1. Drink vinegar (couple shots every day) gross as fuak but if thats what it takes, thats what it takes.
2. Wizinator!! Helped 3 of ma homies, u can buy them at certain head shops. (they look like dicks but inside it has nutrients that relates to urine, basically fake dick with fake piss inside it) i've got a funny story about it though, one of my friends ordered one but recieved a black penis, he was fuaked, it came up hot but his po laughed and let off a warning.
3. Work out as much as u can
4. Drink a ton of water, and thus piss ur brains out
hope this helps
