Fentanyl’s Effects on the Brain & Body

Like heroin, morphine, and other opioid drugs, fentanyl works by binding to the body’s opioid receptors, which are found in areas of the brain that control pain and emotions.

After taking opioids many times, the brain adapts to the drug, diminishing its sensitivity, making it hard to feel pleasure from anything besides the drug. When people become addicted, drug seeking and drug use take over their lives.

Fentanyl’s Effects Include:

• Extreme happiness
• Drowsiness
• Nausea
• Confusion
• Constipation
• Sedation
• Problems breathing
• Unconsciousness
