How Long Does THC Stay In The System Post Quitting Smoking?

I recently stopped smoking marijuana for job opportunities. I have been smoking marijuana for 5 years on a regular basis, multiple times a day (less than 1 gram a day). I am a healthy female, a vegetarian with an appropriate BMI and I stay away from toxins including cigarettes and alcohol. Can you give me an idea on how long THC will be detectable in my urine? Thank you in advance.
