// HARM REDUCTION PROTOCOL — PUBLIC HEALTH DATA

Comprehensive Drug Harm Reduction Guide

This guide provides evidence-based, non-judgmental harm reduction information for people who use substances. The goal is to reduce risks and prevent overdose deaths. This content is based on data from public health organizations and peer-reviewed research.

DISCLAIMER: This information is provided for public health and harm reduction purposes only. It does not constitute medical advice, and it does not promote or encourage drug use. If you are struggling with substance dependence, please contact SAMHSA National Helpline: 1-800-662-4357 (free, confidential, 24/7).
// UNIVERSAL RULES — APPLIES TO ALL SUBSTANCES

Universal Harm Reduction Rules

[ CORE PRINCIPLES ]

01Test before use — Use fentanyl test strips and reagent test kits (Marquis, Mecke, Froehde, etc.) on every substance before consumption. Fentanyl contamination affects all drug categories including stimulants.
02Never use alone — The Never Use Alone hotline (US: 1-800-484-3731) connects you with someone who will call emergency services if you stop responding. In the UK, contact Frank: 0300 123 6600.
03Start low, go slow — Unknown potency is the primary cause of overdose. Always start with a fraction of what you think is a normal dose and wait for full effects.
04Avoid poly-drug combinations — The most dangerous combinations are multiple depressants together (opioids + benzos + alcohol + GHB). These combinations amplify respiratory depression and are responsible for the majority of overdose deaths.
05Know your tolerance — Tolerance drops rapidly after any period of abstinence (illness, incarceration, treatment). Returning users overdose at doses that were normal before their break.
06Carry naloxone — Anyone who uses opioids or is around people who do should carry naloxone (Narcan). It reverses opioid overdose with no effect if opioids are absent. Available free from many pharmacies and harm reduction organizations without a prescription in most US states.
07Use clean equipment — Needle exchange programs (NEPs) provide free sterile supplies. Never share needles, pipes, or straws — HIV, Hepatitis C, and bacterial infections transmit through shared equipment.
08Harm reduction is not enabling — Providing accurate safety information reduces death and disease. Non-judgmental support is consistently more effective than punitive approaches.
// OPIOIDS — HIGHEST OVERDOSE RISK

Opioids (Heroin, Fentanyl, Prescription Opioids)

Opioids carry the highest overdose risk of any drug class. Respiratory depression (breathing slows to a stop) is the cause of death. Since the fentanyl crisis, all opioids — including those purchased on darknet markets — must be assumed to contain fentanyl regardless of their stated identity.

[ OPIOID-SPECIFIC RULES ]

01Test every batch with fentanyl test strips — a positive result does not necessarily mean you cannot use it, but it means you must use an extremely small initial dose
02Fentanyl does not distribute evenly ("hot spots") — test multiple areas of the same batch
03Do not mix opioids with alcohol, benzodiazepines, GHB, or any other CNS depressant — this is the most common cause of fatal overdose
04If someone is unresponsive, breathing very slowly (<1 breath per 5 seconds), or making gurgling sounds — administer naloxone immediately and call 911
05Good Samaritan laws in most US states protect people who call 911 for an overdose — you are unlikely to face charges for seeking help

Overdose Response (Opioids)

  1. Try to rouse the person — call their name loudly, rub knuckles firmly on their sternum (sternal rub)
  2. Call emergency services (911) immediately — do not delay this step
  3. Administer naloxone (Narcan) — nasal spray into one nostril, or injection if you have injectable form. A second dose can be given after 2-3 minutes if no response.
  4. Perform rescue breathing if the person is not breathing — tilt head back, lift chin, give one breath every 5 seconds
  5. Place in recovery position (on their side) if breathing but unconscious — prevents choking
  6. Stay with the person — naloxone wears off in 30-90 minutes and the overdose may return if the opioid is long-acting
// STIMULANTS — MDMA, COCAINE, AMPHETAMINES

Stimulants (MDMA, Cocaine, Amphetamines, Methamphetamine)

[ STIMULANT SAFETY ]

01MDMA — Test with Marquis (purple/black = MDMA), Mecke, and Simon's reagents. Do not redose too soon. Space MDMA use by at least 3 months to minimize neurotoxicity risk. Maintain hydration (500ml/hour if active, 250ml/hour if resting).
02Cocaine — Test with fentanyl test strips and a cocaine-specific reagent. Never share straws (Hepatitis C transmission risk). Rotate nostrils to allow nasal tissue to recover. Heart conditions are significantly exacerbated by cocaine use.
03Amphetamines/Methamphetamine — Sleep deprivation compounds stimulant risks severely. Maintain nutrition (stimulants suppress appetite). If psychosis develops (paranoia, hallucinations), seek immediate medical help.
04Do not combine stimulants with MAOIs (certain antidepressants) — potentially fatal serotonin syndrome risk
05MDMA + MDA or MDMA + amphetamines significantly increases serotonin syndrome risk — avoid combinations
// BENZODIAZEPINES — DEPENDENCE RISK

Benzodiazepines (Xanax, Valium, Clonazepam)

[ BENZO SAFETY ]

01Benzodiazepines have among the most dangerous withdrawal syndromes of any substance — abrupt cessation can cause fatal seizures. Never stop suddenly after regular use; taper gradually under medical supervision if possible.
02Designer benzodiazepines (flualprazolam, etizolam, etc.) sold on darknet markets may be significantly more potent than pharmaceutical benzos — use extreme caution with dosing.
03Combining benzodiazepines with opioids is the most common cause of overdose death — this combination causes profound respiratory depression even at doses individually considered safe.
04Tolerance and dependence develop rapidly — daily use for as little as 2-4 weeks can produce physiological dependence requiring medical management to quit.
// PSYCHEDELICS — SET AND SETTING

Psychedelics (LSD, Psilocybin, DMT, Ketamine)

[ PSYCHEDELIC SAFETY ]

01Set and setting — Your mental state and physical environment profoundly affect psychedelic experiences. Avoid use during periods of psychological instability, trauma, or while taking SSRIs (reduced effect + serotonin syndrome risk).
02Sitter — Having a sober, trusted person present is valuable for difficult experiences. They should know not to panic and to provide calm reassurance.
03Test LSD carefully — Reagent testing (Ehrlich) confirms the presence of indole alkaloids but cannot distinguish LSD from 25i-NBOMe. Ehrlich negative = definitely not LSD. NBOME compounds are bitter on the tongue — real LSD is not.
04Ketamine — Bladder and urinary tract damage develops with heavy regular use. Use infrequently (no more than once per month) and stay very well hydrated. Dissociative "k-holes" can result in injury from falls — use in a safe, seated position.
