so I have a urine test coming up in about 1-3 weeks and I haven't smoked for about 4-5 weeks which was only a little amount as I'm a relatively light smoker to begin with anyways I have about a half gram or less of weed and I'm wondering the risk of pissing dirty in 1-3 weeks if I smoke it?? I'm a male 5'6 125 lb with a pretty high metabolism
