WHY TEST LSD?

Over the last few years a new drug called 25i-NBOMe has appeared on the illicit drug market. Like LSD, this drug is active at a microgram level and can easily be absorbed into a tiny piece of blotter paper. It can also appear as a liquid or powder. 25i-NBOMe produces visual effects like LSD, but unlike LSD it has a known toxicity profile and can be very dangerous. Dozens of people have died after accidentally consuming 25i-NBOMe, thinking it was LSD.

Ehrlich’s reagent can identify LSD and help you rule out 25i-NBOMe. Ehrlich’s’s reagent tests for a class of drugs called “indoles.” LSD is an indole, and all indoles produce a purple color reaction with Ehrlich’s. 25i-NBOMe is not an indole, and will not react with Ehrlich’s.

NOTE! While there are other psychedelic drugs are in the indole class, most of either them cannot be dosed small enough to fit on blotter paper, or else they are not orally active. Most of them also have a strong, metallic bitter taste, unlike LSD.

HOW TO TEST LSD?

1 Cut off a tiny corner of your blotter paper or gel tab and place it on a white, ceramic plate (or put a drop of your suspected LSD liquid on the plate).

2 Hold the bottle an inch or two above the sample and carefully place one drop of reagent onto it.

3 Observe the color change over the next few minutes. The reaction can take several minutes, so be patient. Be careful not to confuse the reaction with purple dye in the blotter art. A purple reaction strongly indicates LSD.

WARNING! Blotter can also sometimes contain the powerful synthetic opioid carfentanil. To test blotter for carfentanil and other fentanyl analogs, use our fentanyl testing strips.
