Question : I'm a 5'6" female weigh115 lbs. was an occasional smoker of pot until month ago. I then smoked two times a day for 3 weeks. I stopped 3 days ago and have to pass urine test in 4 days. What should I do? Any chance I'll pass?

Brief Answer:
Marijuana is detectable in urine 7 - 100 days after regular use.

Detailed Answer:
Hello and welcome to HCM,

If you used regularly for a few weeks, then it can take 7-100 days for your body to clear enough of it out to not be detectable on a urine test. It typically clears out in 1 - 3 weeks but in some people can last longer

A lot has to do with your genetics, metabolism, and the sensitivity of the particular urine test that is used.

Is there any way you can put the test off?

No way to postpone. It's essential I pass this test. I can't be very active due to bruised ribs. I've been drinking as much as I can. Seem to have high metabolism.

Brief Answer:
Good luck - I hope it works out.

Detailed Answer:
Sometimes if the urine sample is too dilute, the test will be rescheduled. That may buy you more time.

I wish you good luck.
