"I can confirm that he had used illegal drugs. I do not want to comment on what kind of products, but he had consumed some," police prosecutor Paal-Fredrik Hjor Kraby told AFP
. The prosecutor wouldn't elaborate on what substances Breivik had taken but did say, "it was obvious he had used steroids, but he also used other drugs."
, who is being held just outside of Oslo at the Ila prison
in the village of Eidsmarka, has admitted to using anabolic steroids in his 1,500 page manifesto
and other body and mind-altering substances.
The Christian Post reported
that before the shooting the mass murderer had ingested a 'super cocktail' of drugs commonly called an 'ECA stack' or 'e-stack'. An 'ECA stack' is a dangerous combination of ephedrine, a stimulant and decongestant, mixed with caffeine and aspirin. Breivik claimed "the combination of the three drugs kept him alert, strong and mentally focused. It also increased his aggressiveness and physical performance."
Anders Breivik, who has admitted to committing the worst massacre in post-war Europe has been described as cold and distant by his attorney Geir Lippestad. Lippedstad says his client, who thought of himself as a warrior who was involved in a war, "took the illegal drugs to be 'strong, efficient and awake' for the attacks," reports Digital Journal
Authorities have also confirmed the court-appointed psychiatrists who were assigned the task of evaluating the mental state of Breivik at the time of the killing are reviewing the extremist's manifesto, as well as the files and tapes from the interrogation by police officers and will soon begin interviewing Breivik at the Ila maximum security prison.
