I am a daily smoker a blunt a day except on maybe an occasion. I stopped for 10 days str8. Then I smoke a half of a blunt one day and the other half the next. I stopped for 2 days the had a small amount which wasn't even a half of a blunt. I'm 5'4 and weigh 172. How long will it take to clear my system by Wednesday? What can i do to pass a piss test? I'm a female. Can I drink a lot of water? I do get exercise at work because I walk a lot and I walk fast. Help please.
