Stimulants
N-Isopropylbenzylamine (N-Iso)
Street names: N-ISO, Iso, The meth mimic
Overdose? Act now. Call emergency services — say "unresponsive, not breathing". Give naloxone for opioid-like signs. Hotlines
⚡What it does
- Essentially inactive — the disappointment is the effect
- Sold as meth, sometimes with a little real meth on top ('twisted dope')
⚠Key risks
- THE SCAM: N-iso is the most common meth adulterant — users pay meth prices for inert crystals
- Identifying: N-iso is harder, doesn't 'crack back' the same, bitter-numb difference (subtle)
- Cuts reduce effective dose → users take more → when real meth appears, overdose
- Harm reduction: test kits, start small with any new batch
✚Overdose signs
- (As adulterant) — none directly; the danger is the unknown real-meth dose in the same bag
