GHB / GBL

1,4-Butanediol (1,4-BDO)

Street names: BDO, 1,4-B, One Four, Gold cleaner, Thunder Nectar

1,4-Butanediol (1,4-BDO) — Clear, odorless-to-sweet viscous liquid; sold as 'cleaner', 'extract', or industrial solvent

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
