From DEA: https://www.dea.gov/resources/facts-about-fentanyl

> Fentanyl is being mixed in with other illicit drugs to increase the potency of the drug, sold as powders and nasal sprays, and increasingly pressed into pills made to look like legitimate prescription opioids. Because there is no official oversight or quality control, these counterfeit pills often contain lethal doses of fentanyl, with none of the promised drug.

From Riley county: https://www.rileycountyks.gov/2050/Fentanyl-and-Opioid-Aware...

> Unlike most opiates, fentanyl can be lethal with the first use. It only takes a two-milligram dose, similar to 5-7 grains of salt, to cause death for an average size adult.

People ODing on Fentanyl often don’t even know whatever they took had it.
