How isolation fuels opioid addiction
Summary
I thought that I often heard stories about opioids this year thus I checked why.
According to my research, a science magazine in the U.S. seemed to have said that people's lasting pains must be taken away by medicines of opioids. After that, the number of opioids’ fatalities was dramatically increasing in 2016 more than the number of traffic and suicide fatalities. Although some doctors knew that, patients who used opioids have become opioid addiction.
And then the speaker found that not having opioid-receptor linked with terrible loneliness by herself experiences.
Taking many opioids fills in opioid-receptor in your body, it makes social interactions difficult to feel rewards, and isolation births more feeling lonelinesses that the situations are social disconnections, addictive drugs, abnormal neurotransmission on involuntary movement and compulsive behaviors. It converges in the striatum that places in your brain. Like that, isolation fuels opioid addiction. This is the opioid crisis.
