Compared to drinking water during a meal or after a meal, it could take the same amount of water anywhere from 45-120 minutes to absorb!

After smoking pot, your THC level in urine is about 100 ng/ml, but 5 days later it will be about 50 ng/ml. You will pass a urine test for sure the next day.

Can you test for THC in your urine?

Surprisingly, yes. As was said before, urine tests check for THC-COOH, not THC itself. THC-COOH is a metabolite of THC, and the body needs some time to metabolise THC into THC-COOH and excrete it through urine. According to studies, the peak concentration of THC-COOH in urine comes about 4 hours after smoking.

How much THC is in your urine after smoking a joint?
