You always hear about random people who just one day, seemingly out of the blue, went on a rampage. The media then starts digging into that person`s history fervently and nothing is left out. Not even his medical history. By searching through a killer`s medical history we wouldn`t be surprised to find out that they were receiving medications like painkillers, antidepressants and many others.
People have often assumed that it was the medication that suppressed those criminal tendencies until it all blew up, but what if this is not exactly the case. What if it is the exact way around. Could some drugs cause homicidal tendencies in people?
A recent study published by Finnish researchers has revealed that in fact, there are some drugs that can affect and alter a person`s state of mind and can have a significant role in homicide cases.
The greatest culprits are painkillers and diazepam compounds. As far as antidepressants go, they do indeed pose a greater risk, but it is not as high as the one induced by painkillers and diazepam.
It was suspected that drugs given to treat nervous system problems, could alter the behavior of a person and it was studied for a long time to understand whether or not, they could lead a person to commit a murder.
The head scientist who conducted the study says that, in his opinion, the reason why these substances could have a factor in a person`s choice to commit a murder, has to do with the effect that the drugs have on the impulse of a person, meaning they are less likely to suppress their negative impulses.
However, the big surprise of the study came when it was revealed that painkillers also have such an effect on a person`s nervous system. The risk they posed was actually higher than the one posed by diazepam substances.
Opiate painkillers were associated with a 92% increased risk and AINS painkillers were related to a 206% increase in risk. The results are dumbfounding when we take into account the fact that antidepressants were associated with a 31% increased risk and benzodiazepines with a 45% increased risk. Researchers concluded that in many cases painkillers affect emotional processing whereas diazepam weakens impulse.
Most of those who were eligible for the study were males, around the age of 36 and less that 4% of the had more than one victim. A common factor found in all the murders was alcohol consumption, in around 79% of the cases.
