How to Test LSD (Acid)

LSD usually comes on blotter paper (tabs) or dissolved in a liquid. LSD can’t be identified visually. We recommend testing LSD with at least two tests.

  1. The primary test for LSD is the Ehrlich test. Which yields a purple color if LSD is present.
  2. We also recommend the Hofmann test, as a secondary test for LSD.

Geltabs (small squares of gelatin containing LSD) can be tested by placing a drop or two of the test liquid on a very small amount of the geltab. Over time, a purple reaction color will appear with Ehrlich if LSD is present. Larger gelatin samples (such as jello squares) can’t be tested. Brownies, sugar cubes, cookies etc. can’t be tested with the kit because they contain too much foreign material.

Harmful compounds such as DOB, DOI, 2C-I-NBOMe don’t yield a color change with the above tests.

You may use the Marquis and Mecke tests to screen for harmful compounds such as 25I-NBOMe, which will yield a dark color (brown/black) fairly quickly.

For a visual demonstration, please see the following:

In summary:

Primary test: Ehrlich reagent
Secondary test: Hofmann reagent

If the above don’t produce a color change after 10 minutes or so, then you don’t have LSD. That being the case, you can use the following to tests to help identify your sample.
