How to detect NBOMes?

How to detect NBOMes: if you intend to use LSD (“acid”), first you need to check it using a test kit to rule out presence of dangerous adulterants such as NBOMes. Pure LSD can be laid on any kind of blotter paper (or other surface) and can’t be identified by appearance. To test for NBOMes use reagent tests Ehrlich, Hofmann, Marquis and Mecke in single-use or multiple-use test kits. To detect fentanyl or test for fentanyl analogs it’s recommended to use fentanyl test strips.

Drug tests presumptively indicate PRESENCE, but not PURITY or QUANTITY. Use different tests to improve accuracy and to detect adulterants – 90% of adulterants will react with 1 out of 3 reagents, and 95% with 1 out of 5.

A positive or negative test result does not indicate if the substance is safe. No substance is 100% safe.

How can I detect NBOMes?

BEFORE using NBOMes test kit

  • It’s RECOMMENDED to record the reaction to compare later

STEP ONE for testing NBOMe blotters / tabs / powder

  • Take a (small) corner of your tab, no bigger than a head of a needle – like this •.
  • Put it on a suitable testing plate, preferably a spot test plate or the bottom/underside of a ceramic mug (example). *If using single-use vials insert the sample and observe, as the reagent is already within.
  • Add one (or two) drops of an Ehrlich reagent test (or other supplied) on the sample and wait for the results.
  • Check reagent test results in instructions.
LSD how much blotter
How to test LSD? Myth: Reagent test wastes a lot of LSD. In reality on the contrary, use the smallest samples possible to cut off. LSD is usually evenly distributed. Who can test less?

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 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.
Ehrlich Reagent and Hofmann Reagent
Basic LSD reagent tests differences: Hofmann reagent reacts slower than Ehrlich. If blotter seems to turn blue/dark this is still a positive result and indicates the presence of LSD.

AFTER using an NBOMe test kit

  • OPTIONAL: Pour baking soda over a finished reaction to neutralize used reagents.
  • Wash testing surface under running water.

FAQ

  • BITTER tasting tabs. Just because a blotter/tab tasted (slightly) bitter doesn’t mean that it wasn’t acid. Ink can be bitter but so are many other chemicals. Hofmann himself in his notes wrote pure LSD-25 has a slight bitterness.
  • 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.
  • Speed of the reaction does not indicate quantity nor purity. However, if you are having trouble interpreting your result try using a bigger sample.
  • How many tests can you get from one test kit? A multiple-use test kit lasts up to 100 (5 ml) or 200 (10 ml) tests. Each drop equals one test. A single use-test kit contains 2 disposable ampoules (2 tests). A single fentanyl test strip is enough for one test.

How to check if NBOMe reagent test works?

  • Test any substance and compare color reactions with instructions. It’s easiest to use 5-HTP or melatonin with Ehrlich reagent, which should turn pink / purple or blue.
  • Keep a sample to compare later in case of doubt. If control sample reacts fine, it means the reagent still works.
