My multivitamin has 1.7 mg B2. I took the first test today around noon and had peed 2 or 3 times before that and drank about 3 glasses of water. The next time was a few hours later with only another glass of water.
kat333 Reviewed by kat333 on . Drug test tomorrow My husband is taking a drug test tomorrow, he failed a home test so he's going to use my urine. He smoked about 3 weeks ago and I did about a month ago. I took 2 home tests and both showed a faint line which according to that means it's negative. Is there anything I can do tonight just to be on the safe side? I would have rathered a darker line on the test. Rating: 5
