so i have been scouring the web, and i have also have recently posted here on a similar topic. how to beat random drug tests. let me start by saying that i know that the best way to pass this kind of test is to be clean. duh! my question is this, has anyone here, PERSONALLY used a urine substitute, synthetic and/or real, to pass a spot drug test? how about a urine additive? does anyone have FIRSTHAND experience with these kind of products? Nuklean Co, Spike, and Testclear are most prominent in the search results. do they work? i really just want some FIRSTHAND experience/results about using these type of products. also i want to smoke some pot again… any/all help/replies are welcomed!
