 Depend on it. Some people won't give you the real talk on drugs, but it's time we know the facts. Fentanyl is killing people. It's a powerful opioid, often made illegally and commonly mixed with illicit drugs. It can even be pressed into counterfeit pills that resemble prescription medications. Just two milligrams, about the size of a few grains of sand, can potentially be lethal. This isn't an ad to scare you, but it is an ad to make you think twice. Get the facts.
