This temporary homepage provides practical, evidence-based harm reduction information. The goal is to help people make safer decisions, recognize emergencies early, and access support — without judgment.
/READ_GUIDELINESYour safety matters.
Knowledge saves lives.
Start Low, Go Slow
Use the smallest amount possible and wait to assess effects before taking more. Potency varies widely, especially with opioids and novel substances.
Never Use Alone
Have a trusted person nearby or use a check-in service. If you must be alone, tell someone where you are and what you took.
Test Before Use
Reagent tests and fentanyl test strips can detect adulterants. No test is 100% reliable, but testing significantly reduces unknown-risk exposure.
Avoid Mixing
Combining depressants (opioids, alcohol, benzodiazepines) dramatically increases overdose risk. Mixing stimulants raises cardiovascular strain.
Know the Source
Substances from unverified sources carry higher adulteration risk. Assume any powder, pill, or vape may contain fentanyl or other potent analogues.
Plan Ahead
Ensure access to naloxone, a charged phone, hydration, and a safe environment. Set limits before use, not during.
Why Testing Matters
Adulterated substances are a leading cause of overdose deaths. Fentanyl and its analogues are often present in opioids, counterfeit pills, cocaine, and MDMA — frequently without the user's knowledge.
Testing Methods
- Fentanyl test strips (FTS): Dissolve a small sample in water, dip the strip, and read results per manufacturer instructions. A single line typically indicates fentanyl presence.
- Reagent kits (Marquis, Mecke, Mandelin): Color-change tests help identify substance class. Use multiple reagents for better accuracy.
- FTIR / lab testing: Spectroscopy services at harm reduction sites provide the most detailed analysis when available.
Testing Limitations
- Test strips may not detect all fentanyl analogues or new psychoactive substances.
- Homogeneous mixing is not guaranteed — test multiple points from a batch.
- A negative result does not mean a substance is safe, only that the tested portion did not detect the target compound.
Opioid Overdose — Act Immediately
- Check responsiveness. Shake shoulders, shout their name. No response = emergency.
- Call emergency services (911 in the US, 999 in the UK, 112 in the EU). Many regions have Good Samaritan protections for overdose calls.
- Administer naloxone (Narcan). Nasal spray: one spray in one nostril. Injectable: 1 mg intramuscularly. Repeat every 2–3 minutes if no response.
- Rescue breathing. Tilt head back, lift chin, give one breath every 5 seconds if they are not breathing.
- Recovery position. If breathing resumes, place them on their side to prevent choking.
- Stay until help arrives. Naloxone wears off in 30–90 minutes; re-sedation is possible.
Signs of Opioid Overdose
- Unresponsive to voice or touch
- Slow, shallow, or stopped breathing
- Blue or gray lips, fingertips, or skin
- Pinpoint pupils
- Gurgling or snoring sounds (agonal breathing)
Stimulant Overdose / Overamping
- Move to a cool, calm space. Offer water in small sips.
- Monitor for chest pain, seizures, or extreme agitation — call emergency services.
- Do not give more stimulants. Benzodiazepines may be needed in hospital settings for severe agitation.
- Cool the body with damp cloths if overheating; watch for heatstroke symptoms.
Injection Safety
- Always use sterile, unused needles and equipment. Never share works.
- Rotate injection sites to reduce vein damage and infection risk.
- Use sterile water and clean surfaces. Alcohol swab the site before injecting.
- Dispose of sharps in a sealed puncture-proof container.
Inhalation & Nasal Use
- Use clean straws or pipes; never share inhalation equipment.
- Chop powders finely and avoid shared surfaces to reduce infection transmission.
- Alternate nostrils and rinse with saline to reduce tissue damage.
General Health
- Stay hydrated and eat regularly — especially with stimulants.
- Get regular health screenings including hepatitis C and HIV testing.
- Sleep deprivation and malnutrition amplify both short- and long-term harms.
- Seek medical care for wounds, abscesses, or persistent symptoms without delay.
