2C-B-FLY-NBOMe
Aliases: Cimbi-31, Nbome-2c-b-fly, 2cbflynbome
Summary
Microgram-scale potency requires precise measurement - always use a 0.001 g (1 mg) accurate scale or volumetric dosing. Many NBOMe hospitalizations and fatalities involved misidentified blotters; 2C-B-FLY-NBOMe has a distinctly bitter/metallic taste and oral inactivity when swallowed. Produces stronger peripheral vasoconstriction than parent 2C-B-FLY - cold extremities and limb numbness are common.

Effect Profile
Scores (1–10) curated from multiple sources:
- Effect keyword matching from PsychonautWiki catalog
- Weighted by importance: core (×3), major (×2), minor (×1)
Strong visuals, body load, and headspace with moderate auditory effects
Strong sensory enhancement with moderate stimulation, mild euphoria, low empathy
Tolerance
Tolerance Decay
Rapid 5‑HT2A desensitization produces short-term tachyphylaxis (hours–days). Functional tolerance typically halves within ~1 week and returns to near-baseline by 2–3 weeks; cross-tolerance with other classic psychedelics is expected but not fully quantified.
