In 2005, I used to get stoned like once or twice a week for the early part of the year. In July of 05, I stopped and didn't have MJ until about the beginning of April of this year. I didn't have as much as I used to, and very small hits. The last time I had it was the beginning of July. I am trying to get a job at Harrah's and heard they do drug testing. I know there is a 90 day limit, but I'm at like 60-65 days now. I really want this job, and I haven't been confirmed for taking the test yet, but I want to be safe and possibly prep my hair.
I have long hair (to mid back) that has been dyed since I had my last hit. If I did the Macujo method before taking the test (that is if I am considered for the job), do you think my hair would be okay. Do they usually cut hair from the top of the head and discard the rest because the rest of my hair (the ends) are probably full of MJ.
I am so happy to have found this website! It is really awesome! Thanks for your help!
