Serious question for those of you who have actually been drug tested or know anything about how they work.
My friend had to get drug tested for his job today (by a legit doctor, not some home 24 hr shit). The last time he smoked was 10 days ago, but before that he was probably smoking about every day for a week, and before that probably about once a week for a long time. He's been drinking a lot of water, and today before going to take his test he took 2 b12 vitamins and a multivitamin, and drank 3-4 water bottles.
Do you think he'll pass, honestly?
