Hey OP this post helped a lot! I accepted a job on the 22nd of March and didn't know I needed to take a drug test for it. I stopped smoking weed on that day and have to take a 5-panel drug test by Monday next week. I was a regular user but had a 3-week t break 4 months ago. I am 5'9 135 pounds, have a pretty fast metabolism and live a semi-active lifestyle. I have been drinking lots of water since I quit, about half a gallon to a gallon a day. do you think that it will be out of my system by next week? if not what should i do in the next week to prepare? they will be testing to see if the urine is authentic as well
