How to Test LSD with Hofmann Reagent
Hofmann reagent is similar to Ehrlich but uses a different solvent, making it more sensitive for LSD at very low concentrations.
Expected Result
Blue / Purple
Reaction speed: Slow (1-5 minutes)
How to Test
- 1Place a small sample (match-head sized) on a clean white ceramic testing plate.
- 2Add 1-2 drops of Hofmann reagent to the sample.
- 3Observe the color change within 3-5 minutes. Some reactions take time to develop — be patient.
- 4Compare your result to the expected color above. Take a photo if you plan to share for verification.
