Changa Facts
Psychedelic;
Description
Changa is a smokeable psychedelic preparation combining freebase DMT with β-carboline-rich plant material from Banisteriopsis caapi or Peganum harmala.[1] The β-carbolines block the enzyme that would otherwise destroy inhaled DMT within seconds, extending the experience to 15–40 minutes.[2]
Subjective effects include vivid geometric visuals, internal hallucinations, apparent entity contact, ego dissolution, and profound temporal distortion.[3] The MAOI component smooths DMT's characteristically abrupt onset into a more gradual emergence with greater narrative continuity than freebase DMT alone.
No physical dependence or withdrawal has been documented for DMT or β-carboline alkaloids.[4] The most serious risk is serotonin syndrome — dangerous overheating and possible seizure — when Changa is combined with antidepressants, a danger compounded by its built-in MAO inhibition.[5]

Seek help immediately if
Most difficulty is psychological (intense fear, panic, confusion) and passes with calm support — the signs below mean seek emergency help:
- Very high body temperature; hot, dry skin
- Seizures
- Chest pain; fast or irregular heartbeat
- Severe muscle rigidity, tremor, or twitching (possible serotonin syndrome)
- Cold, pale, or blue fingers/toes — severe vasoconstriction (notably NBOMe / DOx)
- Persistent vomiting; unconsciousness; uncontrollable agitation or risk of self-harm
What to do
- Stay calm and reassure — remind them they took a drug and the effect will pass
- Move to a calm, quiet, safe space with low light; reduce noise and sensory input
- Keep them from harm — they may act on fear or confusion; stay with them, don't leave them alone
- Talk them down gently; don't grab or restrain unless they're in danger
- For the medical signs above (overheating, seizure, chest pain, vasoconstriction, unresponsive) call emergency services
- If overheating, cool the body; be ready to give rescue breaths / CPR
The experience is time-limited and usually resolves with calm reassurance in a safe setting — psychological first aid, not medication. Serious physical harm is uncommon for classic psychedelics (LSD, psilocybin) but real for some potent phenethylamines (NBOMe, DOx), where hyperthermia, seizures, and vasoconstriction warrant emergency care.
