I just have a few question about home testing. My parents randomly test at home with dip stick drug tests that they bought off the internet. I was wondering if those test for temperature. And if they dont how long will pee keep for in a bottle before it doesn't work for a test(not frozen).

Ok and then I got some other basic questions. Will taking a multivitamin that has a bunch of b vitamins and 50 mg niacin help to make me test clean faster?

Last thing is I want some to tell me how quick they think I will test negative if I smoke just once. I work out 4 days a week, and I take a multi vitamin in the morning and a protein shake at night. I am 16 years old, 5'8", and 175 pounds.
