Alright well here is my time line. Let me know what you think.
August 9 - first time smoking in life ever, little more than 3/4's joint
September 6 - Buzz cut hair and get regular hair cuts after that, also shave body with exception of eyebrows
Early October - Re shave body just to be sure hairs are clean, let regrow after that normally
late March early April - Hair test probably around this time

Again it might seem paranoid but it will give me peace of mind. Are you sure that if I follow this method I'll be clean as a whistle no matter what hair they test on my body?
