What do you think has been behind the mass shootings we have seen for years now? What's behind the Sandy Hook shootings? Was it Adam Lanza's dependence on these "psychotropics"? Check out, for example:
Depression/Relaxation of the CNS is essentially a credit card withdrawal of endorphins/serotonin form your brain’s chemical bank that must be repaid with Mr. Chemical Balance says so.
In addition, during the drugged phase, the brain recognizes that it is slow and stupid and tries to balance by releasing adrenaline or quickly re-taking up the happy chemicals. So it’s possible that even while flush with happy-numby drugs, you soon become flush also with killy-angry chemicals sent to balance the situation. In some cases they neutralize each other - as an acid neutralizes a base. BUT in not all cases do they neutralize eacher.
In some cases, you just have a lot of happy-numby mixed with killy-angry. When one is agressive but can’t feel much, that is when the sloppy-bellicose, or loosey-pugnacious comes out -> as when a drunk gets angry. This can happen with benzo’s, booze, and even opiate pain killers during phases of them kicking in and the body’s attempt to balance them with non-complimentary chemicals, and then comes withdrawal. Withdrawal is neither happy-numby nor killy-angry. Withdrawal is depressy-nervous.
So, There is a phase with all downers, pain killers, opiates, benzo’s and booze, where you are happy-killy. Different biochemical make ups are more or less prone to this phase either more often or more strongly or both.
The point is that while it may seem counterintuitive, happy and killy can coexist because the body’s attempt to bring back its mental and physical acuity after being shot up with dope results not in a canceling affect as with acid and alkaline or hot cooled with cold, but with a hyped upedness coupled with numbness, or happy-go-killiness.
But the link is not to "World Psychology" as reported there, but to "World Psychiatry," the official journal of the World Psychiatric Association":
http://onlinelibrary.wiley.com/journal/10.1002/%28ISSN%292051-5545
However, this is not to the primary source journal paper. I am still trying to find it, but it means that one must register with the Wiley online journal library.

Every mass shooting over last 20 years has one thing in common... and it’s not guns

Can’t say if it was “chicken or egg” but my son’s wife who has admitted using prescription pain-killers, had our son offed because she wanted everything they had.
Then she convinced a local sheriff that he was suicidal.
