Expert Insights

Fentanyl, a synthetic opioid that is 50 times more potent than heroin and 100 times more potent than morphine, is responsible for 82.5% of accidental drug overdoses in the state of Delaware. Considering laboratory testing is the only way to know how much fentanyl is in a pill or powder, the lethal dose of just two milligrams is wreaking havoc on the local community. Consumers of this drug simply have no way to know how much they are ingesting, leaving the state searching for answers to a problem that is on the rise.
