What causes opioid addiction, and why is it so tough to combat? - Mike Davis
TED-Ed・2 minutes read
Opium, morphine, and synthetic opioids like heroin and fentanyl act on the body's opioid system to manage pain and mood, leading to feelings of pleasure but also causing physical dependence and addiction. Withdrawal from opioids can be severe, with symptoms like vomiting and muscle aches, and treatment options include medications like naloxone, methadone, and buprenorphine.
Insights
- Morphine and other opioids act on the body's opioid system by binding to receptors in the brain, affecting pain and mood regulation, while also triggering the release of dopamine for pleasure.
- Prolonged opioid use leads to tolerance, necessitating higher doses for the same effects, ultimately resulting in physical dependence and addiction, with withdrawal symptoms like muscle aches and vomiting requiring specialized treatments like naloxone and maintenance programs.
