OK fair enough. I defiantly do not want to cause anyone to loss a job or fail a test of any kind. Yes many of those studies were dated back to 1982, however the study also references material as recent as 2004. It is a compilation of data and studies over a 20 year plus period. I understand that what I am putting on here may affect someones attitude towards testing and marijuana use. But there is something to be said about advising a guy who has smoked a small amount two months ago that he is best to risk substitution because he is screwed. Or telling him he should drink bleach and what not. And the home tests kits well, I have asked questions about these and so have allot of people. All I have figured out is no one really trusts them or knows much about them. So again my intent is not to screw anyone over. However after reading almost every thread on here and researching the heck out of detection times, I still believe the the majority of individuals will test negative before 30 days with the minority taking longer. Anyone reading this site has to make their own decisions about what to believe and what not to believe.
