i am one of the poor saps that fell for the detox and pills crap. I was told that this is 99.99% effective. I failed the drug test and it cost me BIG. Passyourdrugtest.com and passcannabistest.com are major rip offs. I have threatened lawsuits and received some money back. Pass this info along to everyone you know. It's scam! Substitution is obviously the only way to go. Quickfix 4.0 seems to work for everyone. Read past stuff on these threads. Wish i knew about this site before I got ripped off. They claim everyone passes with their shit, and it is worthless shit, until you fail and then they say" I never told you it's 100%. I'd love to file a class action suit against these rip off artists. Once again, TELL EVERYONE
