Testing Acid (LSD)

LSD and potential adulterants circulating on blotter paper present significant safety risks that necessitate rigorous reagent testing before ingestion. Substances like the NBOMe series are often sold as LSD, yet they carry different physiological profiles and are not orally active. Ehrlich reagent offers a method for identifying the presence of indole alkaloids commonly found in LSD and related analogues. A purple reaction provides a preliminary indicator, but it does not confirm the absence of other compounds. Due to the proliferation of novel research chemicals, personal testing remains a critical practice for harm reduction.
