Experience
Primary effects
- Mescaline provides a significant mood lift and intense euphoria.
- Users enter a strong psychedelic state with visuals and a distinct headspace.
- The experience feels natural and rich, possibly due to its botanical origin.
Peak character
- The peak involves 'flying high' and 'tripping hard' with profound, compelling intensity.
- Users may experience an initial moment of alarm as the effects escalate, followed by a strong sense of euphoria.
- The overall experience is described as 'floating for hours' in a positive, intense territory.
Negatives / side effects
- The preparation (boiling and sipping) can be revolting due to taste.
- Warning of toxicity data for mescaline although 25g dose seems without undue risk.
Aftereffects / comedown
- No significant nausea or negative aftereffects were reported.
Reagent testing
Expected reactions
| Marquis | Orange → green (mescaline) |
| Mecke | Blue/green (mescaline) |
| Froehde | Orange → brown (mescaline) |
Adulterant detection: Echinopsis pachanoi — mescaline content. Marquis going orange/green is characteristic of mescaline. Rapid dark reaction would indicate a different phenethylamine.
Mescaline has a distinctive Marquis profile. Test extracted material rather than raw cactus.
