I know ive heard people say that THC stays in urine for 30 days. But i also heard it only stays in for 7 days. I was wondering, if i got like a half - O and smoked it all by myself, how long would it take to clear my system? Oh, and my mom uses those $15.00 walgreens tests to test me randomly. Also any suggestions on anything that i can take to clear my system would be great.
