Why Do People Get Addicted to Opioids?
The opioid epidemic is a complex issue. In 2016, the CDC reported a 200% increase in opioid-related deaths between 2000 and 2014. Tens of thousands of Americans are dying each year due to an opioid overdose. But why do people get addicted to opioids?
The Human Brain and Opioids The human brain is an extremely complex organ. It’s responsible for all of the functions that make us human. It has almost 100 billion nerve cells. Dopamine is a neurotransmitter that’s released by the nerve endings in the brain that are responsible for things like pleasure, happiness, and motivation. It helps regulate many different human behaviors, such as movement. There are various ways in which people take opioids. They can take it by mouth, snort it, or inject it with a needle. When opioids are taken by mouth or snorted, they go into the bloodstream and are eventually absorbed by the brain. When taken by injection, the effects are felt almost instantly and can last for about a day (maybe even longer).
