The MDMA & Psychedelics Multipack is the best option for testing DMT. It contains the ehrlich reagent which is a “binary test” for the presence of compounds in the DMT family (technical term: indole-containing substances). If it stays clear then there is no DMT present in the sample.
If the ehrlich reagent goes purple then you can corroborate with other tests as follows:
| Reagent Test | Reaction with pure DMT |
| Ehrlich | Purple |
| Marquis | Orange > Brown |
| Mecke | Yellow > V. Dark Green |
| Froehde | No change |
If the froehde reagent changes colour then you know that other compounds are present.
One of the challenges with drugs from plant origins is that plants contain many compounds and these are extracted by the same process. This makes it very hard to tell if any “other chemical” is from the plant or if it has been added by the person making or selling the compound. We recommend that the Best Practice is to discard any drug which has any reaction not compatible with the pure form of the expected substance.
The hofmann reagent can also be used for testing DMT and should only go yellow for pure DMT. Because the hofmann reagent is very sensitive to similar compounds from plants, it can be impractical for testing plant-derived DMT where there are usually strong green (from 5-MeO-DMT) and orange (from gramine) tones also present.
