Can using fentanyl poison me?

Yes, it can poison you if you take too much. Early signs of fentanyl poisoning may include:

• sleepiness
• trouble breathing (it may sound like snoring)
• slow, shallow breathing
• cold, clammy skin
• unresponsiveness to pain or a person’s voice

The most dangerous side effect of fentanyl is it can cause you to stop breathing, which can lead to death.
