Fentanyl is a synthetic opioid which is 100 times stronger than morphine and 50 times stronger than heroin. Simply touching it can cause a person to overdose.

Fentanyl inhibits pain signals in multiple pathways along the brain and spinal cord, and it also causes your brain to make extra dopamine creating sensations of intense euphoria and relaxation. Essentially, it hijacks your body’s built-in system of endorphins by binding to your opioid receptors much in the same way your endorphins do but at a much stronger level. As a result, it suppresses your brain’s ability to detect carbon dioxide levels in the body, potentially causing you to stop breathing. Other side effects include dizziness, chills, vomiting, fainting, difficulty urinating and extreme constipation. Watch AsapSCIENCE’s look into one of the deadliest drugs below.

      1. Cheers. Still churning out the occasional post. I miss your ‘likes’ but very much appreciated them when they were needed. Your blog seems to have grown exponentially.

        1. Well, I would like to think so. But the problem is most of my followers do not get notified of my new posts since I moved to wordpress.org. Since you have become active again, I will be occasionally visiting your site. Cheers! :)

  1. Not to be gross about the subject – but during a stint operation [out-patient procedure], I was given a morphine relaxer. My reaction afterward was being readmitted to the hospital unconscious and one of massive vomiting that would put the Exorcist to shame. I’m quite certain I would never willingly take this stuff!!

  2. What about finding better treatment for those with severe chronic pain so they don’t become addicted? Many people have severe orthopedic pain and surgery seems to offer temporary relief that leads to a need for further surgery.

  3. Its so frightening how casually people take drugs – wonder what can change so people dont want to – knowing risks doesnt seem to help – is it reallu not being aware of damage, peer pressure, homelife or tighter control needed in nightclubs, bars even schools. What do you think would help
