Fentanyl

⚠ Warning

Fentanyl is an extremely potent synthetic opioid.

A very small amount can cause fatal respiratory depression, especially in someone without opioid tolerance. Counterfeit pills and powders may contain fentanyl without the user knowing.

If opioid use is suspected and someone is difficult to wake, breathing slowly, or not breathing:

• Call emergency services immediately.
• Administer naloxone (Narcan) if available.
• Keep the person's airway clear and monitor their breathing until help arrives.

Never use fentanyl alone.

Overview

Fentanyl is a highly potent synthetic opioid used medically for severe pain management and anesthesia. Because of its extremely high potency, illicitly manufactured fentanyl has become a major contributor to overdose deaths worldwide.

Its effects include intense pain relief, sedation, physical warmth and euphoria in some users. However, it can also rapidly cause severe drowsiness, nausea, vomiting and dangerous respiratory depression. The difference between a dose that produces effects and one that causes overdose can be very small, particularly for people without opioid tolerance.

My Review

Overall Experience

It was honestly one of the worst drug experiences I've ever had. The first thing I noticed was intense dizziness and nausea. Very quickly I became completely numb, not just physically, but emotionally and mentally as well. It felt like every emotion had simply disappeared. I wasn't euphoric or relaxed; I just felt like an empty shell of a person.

I somehow managed to get out of my chair and make it to my bed, where I passed out sitting upright against the wall. When I woke up roughly six hours later, I had an awful migraine and discovered I had vomited all over myself while unconscious. Looking back, that's particularly unsettling because vomiting while unconscious could have killed me.

For the next twelve hours I couldn't even think about eating because the nausea was so overwhelming.

This experience completely turned me away from opioids. There was nothing enjoyable about it for me, and it remains one of the few substances I have absolutely no desire to revisit.

What I Enjoyed

• Nothing memorable.

What I Didn't Enjoy

• Extreme nausea
• Vomiting
• Physical numbness
• Emotional numbness
• Cognitive impairment
• Severe sedation
• Migraine

Would I Use It Again?

Tips & Harm Reduction

Practical Tips

• Never use an unknown opioid alone.
• Avoid mixing opioids with alcohol, benzodiazepines or other sedatives, as this greatly increases the risk of overdose.
• If using illicit substances, be aware they may contain fentanyl even if sold as something else.

Harm Reduction

• Carry naloxone (Narcan) if opioids may be present.
• Learn to recognize the signs of an opioid overdose.
• If someone becomes difficult to wake or stops breathing, call emergency services immediately and administer naloxone if available.
• If someone is unconscious but breathing, place them in the recovery position to help reduce the risk of choking if they vomit.
