Fentanyl overdose risk: Why this drug is different
Fentanyl has fundamentally changed the overdose landscape. Traditional harm reduction strategies that worked for heroin are less effective with fentanyl.
Why fentanyl is different
The lethal dose (2mg) is invisible. Uneven mixing creates hotspots where one dose from a batch is lethal even when others are not. It accumulates in fat tissue, creating unpredictable withdrawal timing. Standard naloxone doses may be insufficient; multiple doses may be needed.
Who is at risk
Everyone using street drugs. Fentanyl is found in heroin, counterfeit pills, cocaine, meth, and MDMA. You do not need to be an opioid user to be at risk from fentanyl.
Protection
Test strips reduce but do not eliminate risk. Carry multiple doses of naloxone. Never use alone. MAT eliminates exposure to contaminated street drugs entirely.
The case for MAT
In the fentanyl era, medication-assisted treatment is not just a treatment option; it is overdose prevention. Pharmaceutical-grade buprenorphine or methadone eliminates exposure to the contaminated street supply.
