I'm not a regular pot smoker. The last time I smoked pot was late Thursday night. I probably smoked 2 bowls with 3 other people. The time before that was about a month ago, same situation, same people I'm subject to random drug testing, and surprise surprise I got the phone call this morning. I was freaked out so I went to Walgreens and bought an at home test. It came back negative. I'm still anxious because I have problems believing that pot can go through your system in in 4 days. Is this accurate and I should proceed with my urine or should I use something to replace my urine? I can put the test off till tomorrow but that's the latest. Thank you so much!
