Blood Drug Testing

How accurate are take home drug tests?

I should be clean. I haven't done anything, yet, I take a test and I show up a little positive for both amphetamines and marijuana. They absolutely should both be negative. What is a good, relatively cheap, accurate take home drug test? Thanks! :) Can second hand smoke (marijuana) go into my system, showing up on a drug test?

1. Hey Well, I'm not sure I understand your reasons for testing. As far as accuracy goes, they are all VERY accurate. I don't have any brand names for you, I'm sorry. You know, as far as smoke goes, the sensitivity for a primary user is extremely high, even for a small amount used. Without doing the math, I am leaning pretty strong in the direction of a positive result for a second hand exposure. One minute right next to some one smoking outdoors, probably negative. Five minutes or more in an enclosed area where there is visible smoke in the room, probably positive. I'm sorry I can't give you better information. I'm just going by my analytical chemistry experience and some general pharmacology stuff I just happened to know. I hope some of this was helpful. Good luck, Edward
