Heroin — Safer Use & Harm Reduction

Evidence-based guidance for risk minimisation

Opioide

Harm Reduction

The safest option is always abstinence. If substances are used regardless, evidence-based precautions can meaningfully reduce risk. The guidance below is informational — it does not make substance use safe.

Safer Use Guidance

general

Naloxon immer dabei: Naloxon (Narcan) rettet Leben bei Opioid-Ueberdosierungen. Kostenlos in vielen Apotheken erhaltlich. Jede Person im Umfeld sollte wissen, wie es angewendet wird.

general

Nie allein konsumieren: Bei einer Ueberdosierung kann eine anwesende Person den Notruf (112) rufen und Naloxon verabreichen.

general

Fentanyl-Test-Strips: Strassen-Heroin ist haeufig mit Fentanyl kontaminiert. Fentanyl-Test-Strips koennen Kontamination nachweisen.

general

Niedrige Einstiegsdosis: Toleranz sinkt schnell (nach wenigen Tagen Abstinenz). Nach einer Pause immer viel niedriger beginnen als gewohnt.

general

Saubere Nadeln: Nie Nadeln teilen. Spritzentausch-Programme bieten kostenlose saubere Spritzen.

general

Absolute Kontraindikation: Nicht mit Benzodiazepinen oder Alkohol kombinieren - synergistische Atemdepression, haeufig toedlich.

general

Substitutionstherapie: Methadon- oder Buprenorphin-Therapie ist die evidenzbasierte Behandlung bei Opioidabhaengigkeit - drastisch reduziertes Overdose-Risiko.

Warnings & Contraindications

Overdose kills via respiratory depression — keep naloxone (Narcan) accessible at all times; administer immediately if breathing stops or becomes very slow/shallow
Fentanyl contamination: test every batch with fentanyl test strips — the US/EU supply is now heavily adulterated; a dose that looks identical to the last can be lethal
Never use alone — the NEXT use after a break (jail, treatment, hospital) carries the highest overdose risk due to lost tolerance
Tolerance loss occurs within days of abstinence — returning to previous doses after any break is frequently fatal
Intravenous use risks: HIV, Hepatitis C, bacterial endocarditis, abscesses — use only sterile equipment from needle exchange programs
Withdrawal is extremely uncomfortable but rarely medically dangerous in otherwise healthy adults; medically supervised detox significantly improves outcomes
Never use alone — have someone present who knows how to administer naloxone
Fentanyl test strips are essential; if strip is positive, use a much smaller test dose first
Supervised consumption sites, needle exchanges, and MAT (methadone/buprenorphine) are evidence-based interventions — access them
