Given its pharmacological similarities to LSD, and its likely function as a prodrug of it, 1P-LSD is likely to trigger relevant drug tests in exactly the same way. However, LSD tends not to be included in standard drug tests and is only sometimes tested for in extended screens.
As with LSD, excretion through urine reaches a peak about 4 to 6 hours after administering a dose in humans, but even then, the amounts are quite small. There are four known major metabolites of LSD in humans that are excreted and can be detected in urine for up to 4 to 5 days after ingestion, with observed inter-individual variation.
The average time LSD can be detected in blood is 6-12 hours and in urine is 2-4 days. However, for now, it is not typically included in standard drug screens.
