From the article:
“In the new study, the researchers looked at data collected from about 960 men and women in Finland, ages 13 to 88, who were all convicted of homicide.
They then compared each person who committed homicide with 10 other people who had not committed homicide, but who were the same age and gender, and lived in the same town.
The findings showed that tranquilizers increased the risk of committing a homicide by 45 percent and antidepressant use increased the risk by 31 percent.
But the researchers were surprised to find that the use of anti-inflammatory pain relievers was tied to an increase of more than 200 percent in the risk of committing homicide. Opioid pain relievers elevated risk by 92 percent, Tiihonen said.
The researchers speculate that tranquilizers may weaken people’s impulse control. Other studies have suggested that using certain painkillers may dull processes responsible for processing emotions.
The study is published in the journal World Psychology.”
Gee. Ya think?
