I've been researching the shit out of this stuff and YOU my friend definitely want to take some kind of precaution. I'm using the MAC method, if you google it you'll find the ingredients. Also, for African Americans they say you want to use some kind of perm or relaxer on your hair b/c although everyone knows there's a disparity in the hair follicle testing and African Americans test positive more than white folks do no one is doing anything about it. Your hair is thicker and it's harder to treat the core where the THC is stored. Don't risk it!! Omni Clean is popular, I tried to get some but the idiot at GNC sold it to someone else before I could pick it up so I got All Clear instead. Do your homework, don't panic, pick a method and pray!!! - That's what I'm doing. I'll let y'all know how it goes once I take my test.
