>Just use an NMR

Isn't that expensive? I don't access to a lab that has one...

>IR or UV

I have a blacklight and that works for UV light. I use that to check fluorescence on tabs but just because it glows blue under blacklight doesn't mean much. A lot of things do that, tonic water is one of them. Paired with a test kit certainly both can narrow results but smart scammers know this and will create something that fools both. Also,

>there isnt even an indole in LSD

Mostly incorrect. Indole alkaloids are a class of alkaloids containing a structural moiety of indole.

Scroll down to the ergot alkaloids section where pic attached is. It showcases the tryptophan group on the molecule.

Tryptophan most definitely contains an indole, but it is technically a structural moiety of indole. Even in the IUPAC name [(2S)-2-amino-3-(1H-indol-3-yl)propanoic acid] you see the "indol" part.

Now look at LSD's structure again and see how it has a lysergic acid group.

https://en.wikipedia.org/wiki/Lysergic_acid_diethylamide

Even the IUPAC name for LSD [(6aR,9R)-N,N-diethyl-7-methyl-4,6,6a,7,8,9-hexahydroindolo[4,3-fg]quinoline-9-carboxamide] you see "indolo" in there. While it is not exactly indole, certainly a structural moiety will retain functional characteristics. This is why LSD, and even pure LSA glows blue under UV as they both contain this. An Ehrlich will most certainly test positive for LSD, but it only indicates the presence of indole.
