Hair testing accuracy?????

[chish]

I searched through the forums looking for something like this but can't find it. So if you find one please just post a link.



SWIM needs to know how accurate a hair follicle test is at telling the difference between opiates. Swim has a perscription for oxycodone and have demoral shots for his knee. He also have been using heroin on a regular basis for about a month. SWIM was wondering if he gets a hair test in the next month and a half to three months if he will be ok? SWIM will be getting more pain killers soon for surgery. So will they be able to tell the differance between the pills and heroin? And he also smoked weed about 3 weeks ago. Will they be able to tell? Cocaine about a month ago? Thanks guys!!! Besides the shampoo they sell online is there anything he can do besides cutting his hair? Does the shampoo even work?
