One dose unit of blotter.

Original result from DrugsData showed only 1P-LSD but the Ehrlich reaction showed a strong purple color, which is not consistent with 1P-lSD.
July 20 2021: The originally unidentified substance is now fully confirmed to be tryptamine (CAS #61-54-1) and the lab has confirmed that tryptamine, by itself, turns a strong purple color with Ehrlich's reagent. This sample is now fully confirmed to contain only 1P-LSD and Tryptamine in equal amounts.

Tryptamine is not known to be psychoactive at this dose range, though its possible effects on pharmacology of ergoloids has not been documented in Experience Reports nor in the scientific/medical literature.

July 14 2021: The unidentified substance was tentatively identified as tryptamine (CAS #61-54-1). Working to confirm this. A lab standard has been ordered. When it arrives, we will run it through the GC/MS alongside this sample and will do an Ehrlich reagent color test, as well.
July 13 2021: We have e-analyzed the sample and re-compared it against 1P-LSD, 1B-LSD, and LSD. LSD is absolutely ruled out: it is not present in the sample.

Many thanks to the person who wrote in asking about the discrepancy between our identification and the Ehrlich response!

There is a peak the lab had initially ignored in our reporting, but we are now calling an unidentified. On the unidentified PDF, it is Scan 1108 at 7.199 min. We do not currently know what this chemical is.

The 'uncertain' issue is that the Ehrlich reagent turned purple on this blotter sample but does NOT turn purple with pure 1P-LSD.

We are working on trying to explain this dicrepancy. Three possibilities currently we're exploring:

1) 1P-LSD turns purple in Ehrlich reagent after a long time (now RULED OUT)

2) The unknown we found in the sample (but did not initially report) is turning purple with Ehrlich.

3) The blotter paper, dye, or some other component of the blotter paper is causing the purple reaction with Ehrlich reagent. Note that the unidentified could be a non-drug chemical that fits under (this) reason #3.
