How can such a test be beaten?
While there is some literature on adulterating urine samples to produce false negative results [11], there has been little written that applies specifically to the LSD screening tests. I am asking for …[a description]… of each thing that LSD leaves behind that can be detected, and of each method used to beat each test. The immunsoassay tests vary in their specificity. Some display a relatively low cross-reactivity[13], others a high cross-reactivity[14]. The exact metabolites of LSD in humans have not been fully determined yet, though animal studies have been done. The only verified human metabolite I could find in the literature was N-demethyl-LSD[6] but I did not check all the references.
