Hi, I Am A Medical Marijuana Patient And I Have

Hi, I am a medical marijuana patient and I have been smoking for about 2 1/2 years now. I want to quit smoking to find a different job. I make decent pay but being a single mother and paying for everything can be overwhelming. How long would it take to clear my system for a urine, blood, swab, or hair folical drug testing? I know I can find better employment if I didn't smoke marijuana!
