As for the compound "1D-LSD" (which also has "1D" in the name), several studies show that the ingredient of seized blotter paper printed...

Identification of 1-(thiophene-2-carbonyl)-LSD from blotter paper falsely labeled "1D-LSD".

In this case, three pieces of blotter paper labeled "1D-LSD" and presumably impregnated with this LSD analog, were seized. Several websites indicate that 1D-LSD is 1-(1,2-dimethylcyclobutane-1-carbonyl)-LSD. Because this analog is much more difficult to synthesize than previously...
