Hey guys, I am currently in a situation. I am scheduled for a drug test from today to Monday. I can go whenever I want between those days. I smoked on the 4th of January and it was a surprise test. I went and bought the Herbal Clean carbo20 detox drink and I drank it today. When should I go for my test? Should I have waited to drink it the morning of? Or am I just screwed? Please help.
