Tucibi (also written tusi or "2C") is one of the most misleading product names on the street. The name comes from "2C-B"; a specific phenethylamine psychedelic; but lab analyses from Energy Control (ES), DIMS (NL) and forensic labs across Latin America consistently show that the pink powder sold as tucibi contains almost no 2C-B at all. Typical batches contain some combination of ketamine, MDMA, methamphetamine, caffeine, and an opioid like tramadol or codeine. The pink colour is food dye.

This matters because dosing, duration and risk are completely different depending on what is actually in the bag. A "line of tusi" might be 80 mg of ketamine plus 50 mg of MDMA (a recognisable combination), or it might be 100 mg of meth and a touch of caffeine (very different evening). Two bags sold under the same name in the same city can differ by an order of magnitude in any given ingredient.

Harm reduction

  • Treat every new bag as an unknown substance. Past experience with "tusi" does not predict the next batch. Start at 30–50 mg insufflated, wait 60 minutes, reassess.
  • Lab-test if you possibly can. Energy Control (mail-in, anonymous) is the gold standard in Europe. DIMS in the Netherlands, ChEckiT! in Austria, and SaferParty in Switzerland will analyse a sample for free.
  • Reagent tests alone are misleading. Marquis turning purple just tells you there is MDMA-like material in there — not how much, and not what else is. A negative reagent test on tusi means almost nothing.
  • Assume the worst case for combinations. Treat your bag as if it contains MDMA, ketamine, and a stimulant. That means: no SSRIs, no MAOIs, no tramadol, no cocaine, no alcohol over a couple of drinks, watch core temperature, hydrate moderately (not excessively).
  • Bathroom check at 30 minutes. Hot forehead, racing pulse over 130, pinpoint or unequal pupils, slurred speech: stop, sit, cool down.
  • Plan one substance only. The whole point of tusi is mystery; piling actual ketamine or MDMA on top stacks unknowns onto unknowns.
  • The colour is meaningless. Some sellers use strawberry dye, others use beetroot powder, others use real synthetic colourings. Colour intensity does not correlate with potency or purity.
  • If somebody goes down hard: recovery position, call emergency services, tell them you don't know what was in it. Hospitals in Spain, Colombia and the UK have been seeing tucibi-related presentations for years; they know what it usually contains.

Effects.

Positive

  • Stimulating euphoria
  • Sociability and confidence
  • MDMA-like warmth (when MDMA is present in the mix)
  • Mild visual enhancement (when 2C-B or ketamine are present)

Neutral

  • Pupil dilation
  • Jaw tension
  • Pink-coloured nasal discharge
  • Highly variable subjective experience batch-to-batch

Negative

  • Cardiovascular load from stimulant component
  • Serotonin-syndrome risk if combined with anything serotonergic
  • Disorientation when ketamine is dominant in the mix
  • Comedown shape depends on which ingredients are actually present
  • High overdose risk from unknown stimulant content

Interactions.

Heads up

Many drug combinations are unsafe even at low doses. When in doubt, take less or abstain. Always cross-check with the interaction checker tool.
Dangerous

Combination may cause serious harm. Avoid.

  • maois
  • tramadol
Unsafe

Substantial risk. Combination not recommended.

  • cocaine
  • methamphetamine
  • amphetamine
  • mdma
  • alcohol
  • dxm
  • ssris
Caution

Mild interaction. Use with reduced doses.

  • cannabis
  • ketamine
  • opioids

Testing.

  • ReagentMarquisExpected reactionVariable: MDMA gives purple-black, ketamine/caffeine give no reaction. A non-reaction does not mean the powder is "safe".
  • ReagentMeckeExpected reactionVariable based on ingredients
  • ReagentMandelinExpected reactionVariable based on ingredients
  • ReagentLiebermannExpected reactionUseful if cathinones are present
  • ReagentNotesExpected reactionSingle-reagent tests are unreliable for mixtures. Lab analysis is the only way to know what is in a particular batch.

Cross-check with a secondary reagent. Tests tell you what something isn't, not always what it is.

Harm reduction

FAQ.

How long does Tucibi last?
A typical oral Tucibi experience peaks around 90–180 minutes and then tails off, with after-effects that can run several hours. The exact window depends on dose, body weight and what else you've eaten or taken.
Can you overdose on Tucibi?
Yes. Higher doses sharply raise the risk of acute harm (cardiovascular strain, hyperthermia, serotonin issues for serotonergic drugs, respiratory depression for downers). Stick to the lowest dose that gives you the effect you're after, never re-dose blindly, and use our [dose calculator](/tools/dosage-calculator) before you weigh anything out.
Is Tucibi addictive?
Tucibi can produce psychological dependence with frequent use, especially in unstable settings or when used to self-medicate. Physical dependence varies by substance class; the safest pattern is occasional use with long breaks (often 4–6 weeks minimum) and an honest read on why you're reaching for it.
What does Tucibi feel like?
Common subjective effects include the ones listed in the Effects section above. Set and setting massively shape the experience: a calm space, trusted people, food eaten, sleep the night before, and your own current mood all matter more than most people expect.
Can you mix Tucibi with alcohol?
Mixing with alcohol is rarely a good idea — it dulls your judgement of how much you've taken, dehydrates you, and stacks cardiovascular load. If alcohol is on the table, drink less than normal, alternate with water, and run the combination through our [interaction checker](/tools/interaction-checker) first.
How do I test Tucibi at home?
A basic reagent kit (Marquis + Mandelin + Mecke for most stimulants/entactogens; Ehrlich for tryptamines) gives you a fast presence check. It does NOT measure dose or purity, but it does rule out the most dangerous misrepresentations. See the [reagent guide](/tools/reagent-guide) for expected colors per reagent.
How much Tucibi is too much?
There's no single number that applies to everyone. As a rule, anything above the 'strong' dose range (250-400 mg for the primary route) carries sharply higher risk of acute harm. Start low, don't redose blindly, and remember that purity varies batch to batch.
How long until Tucibi kicks in?
Onset is typically 30-60 minutes via the primary route. Don't redose because you 'don't feel anything yet.' Many people have overdone it by stacking doses during the come-up window.
Can you build tolerance to Tucibi?
Yes. Regular use builds tolerance, meaning you need more for the same effect. This escalation increases both health risk and dependence potential. The best counter is long breaks between sessions (2-4 weeks minimum for most substances, 3 months for MDMA-class drugs).
Is Tucibi tested for in standard drug screens?
Standard 5-panel workplace tests (SAMHSA-5) do not specifically screen for Tucibi. Extended panels (10-12 panel) or specialized tests may detect it. If testing is a concern, research the specific panel being used.
