I've been sober for nearly 4 months, and I just smoked weed yesterday when can i pass a urine test?

There is no way to answer your question based on the info given. It depends on the exact amount that you smoked, how much you weigh, and your body. Smoking weed deposits toxins in your body, and that is what the test will pick up on. Many people have many methods for flushing out your body of those toxins. Some say to drink bleach - don't do this. Drinking lots of water will give you a good flush, but it really will take time.

Average time will take 6 weeks or so to totally flush your system. Of course this is for urine, they could always take a hair sample and find exact timeframe you used - and there is no way to remove the deposits that grow into your hair.

since u were clean before u smoked it wont take long. id say a week give or take. i smoked on a friday took a test on monday and passed. just drink water

2-3 days depending on your weight.

No, water doesn't help

Relapse is common. Get back on the horse.
