LSD Colour Reaction Chart
LSD is tested using Ehrlich and Hofmann as the primary reagents; Marquis and Mecke are only used when LSD isn't detected in the first two tests and the results are inconclusive. Following is a simplified chart of the most common colour reactions for the 4 reagents with LSD.
The sequence of using the LSD reagents is Ehrlich, Hofmann and then Marquis and Mecke.
- The Ehrlich reagent turns pinkish to purple with a positive LSD/LSD analogue sample.
- The Hofmann reagent changes to a blue colour with a positive LSD-25 sample.
- The Marquis and Mecke reagents shouldn't change any colours if there isn't a presence of the dangerous NBOMe. Please note that since Marquis and Mecke reagents are highly corrosive, paper charcoaling is normal and shouldn't be interpreted as a reaction.
