Category comparison — GHB / GBL
| Substance | Class | Top risks | Street price |
|---|---|---|---|
| Phenibut | Not scheduled US | RAPID TOLERANCE — daily use creates dependence in 2–3 weeks; Withdrawal is BRUTAL and dangerous: severe anxiety, insomnia, hallucinations, psychosis, seizures — worse than benzodiazepine withdrawal for some | ~$20–$50 per 50g powder |
| 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 |
