Overdose? Act now. Call emergency services — say "unresponsive, not breathing". Give naloxone for opioid-like signs. Hotlines
⚡What it does
- Converts to GHB in the body — identical effects: euphoria, disinhibition, sedation
- Onset slower than GHB (30-60 min)
⚠Key risks
- GHB-class dangers: razor-thin overdose margin — 1 mL too much = coma
- Severe daily-use dependence with life-threatening withdrawal (like GHB/alcohol)
- Industrial-grade supply = unknown purity/concentration
- Frequently mislabeled or mixed with GBL
- Emergency: no field antidote — airway support only
✚Overdose signs
- Sudden deep sleep/unrousable
- Vomiting while unconscious
- Slow irregular breathing
Category comparison — GHB / GBL
| Substance | Class | Top risks | Street price |
|---|---|---|---|
| 1,4-Butanediol (1,4-BDO) | Not federally scheduled US | GHB-class dangers: razor-thin overdose margin — 1 mL too much = coma; Severe daily-use dependence with life-threatening withdrawal (like GHB/alcohol) | ~$40–$100 per 100 mL industrial |
| GHB (gamma-hydroxybutyrate) | Schedule I/III | Dose curve is razor-thin — 1 mL too much = coma; Frequent dosing needed (90-min half-life) → dependence and brutal 24/7 withdrawal | ~$5–$20 per dose |
| GHB Liquid | Schedule I | Concentration unknown — strength varies bottle to bottle; Mixing with alcohol frequently fatal | ~$60–$150 per 100 mL |
| GHB Powder | Schedule I | Dissolving errors → misdosing; Hygroscopic powder clumps — uneven concentration | ~$40–$120 per 50 g where found |
| GBL (gamma-butyrolactone) | Schedule I | Stronger and faster than GHB; dosing even more unforgiving; Caustic — burns mouth/esophagus undiluted | ~$50–$150 per liter |
| Poppers (Alkyl Nitrites) | Legal to possess | Fatal blood-pressure crash when combined with Viagra/Cialis/Levitra (PDE5 inhibitors) — the classic killer combo; Methemoglobinemia at heavy/repeated use — blood stops carrying oxygen (blue lips, breathlessness) | ~$5–$20 per bottle |
