I have been a daily pot smoker for 20 years. I have quit now for 24 days and plan on shaving my entire body and attemp to grow all new clean hair. My question, as a heavy smoker how long should i wait before i shave? Secondly, i shave my head and will likely have to have my sample taken from my arm pit, chest, arm, or leg hair. Is there a different waiting period for that. I can grow a beard out thay long and may take that route. Btw you are freaking awesome for helping people that are turning things around and doesnt want the past to haunt them.
