How to detect NBOMes?

How to use an NBOMe test kit?

• Check test results with Ehrlich test kit: if testing LSD the exact color of the reaction is not important – the test is of a yes/no type. It will go purple or pink if it is exposed to an indole compound like LSD, an analogue of LSD or a tryptamine. No 0.5cm² blotter can fit an active dose of a tryptamine onto it.
• NBOMe compounds and other phenethylamines (like 2C-B) will not give a colour change with the Ehrlich reagent.

STEP TWO detecting NBOMes

According to Drugsdata.org, LSD tabs are never ‘adulterated’ with something else besides the main component. Dangerous substances missold as LSD, like 25I-NBOMe responsible for many deaths, do not react with Ehrlich and Hofmann reagents, contrary to LSD and other lysergamides.

Only if your tab doesn’t change color within 10 minutes (like this example):

• THEN in addition to this it is good to use test kits Marquis, Mecke or Froehde. These do make the paper go brown but if there is something like DOC present then the liquid itself usually gives a pretty vivid green colour change.
• False positives. To check if Ehrlich test result could be a false positive, use Hofmann reagent to test more specifically for LSD and tell it apart from other indoles. It’s more precise than Ehrlich, but reacts slower. Keep in mind that other reagents are much less accurate/reliable, according to Erowid.org.
