There probably are ways, but I'm betting they're not very reliable. Visit that Erowid site above and look at what it says there, then do a Google search on various anti-drug screen products and see what they say about results with blood screening. I'm betting that's a very tough test to beat.
birdgirl73 Reviewed by birdgirl73 on . My friend's Blood Test Hey, My friend's been an everyday weed smoker for a while now, and he does ciggies too, but no other drug. Anyway, his parents know that he's dealt and smoked weed and shit for a while, so they're trying to find out if he's honestly quit like he told them he has by giving him 2 months to go clean. He's getting a blood test in 1 month now I think he said it was, and wants to get it out of his system as fast as he can. Are there any methods to pass a blood test for drugs? Rating: 5
