According to researchers from Sweden, there can be a link between anti-social behavior and anabolic steroids.

Anabolic steroids are drugs concerned with male sex hormones that can be taken in an oral as well as injectable form and often used and abused by sportsmen and celebrities to build muscles and stay young.

However, long-term use and abuse of steroids can lead to severe health complications such as liver cancer and kidney disease.

From News-Medical.Net:

Apparently non-prescription steroid use has been linked previously to a number of psychiatric conditions and changes in behaviour and there have been reports of groups such as bodybuilders using anabolic androgenic steroids where hypomania or manic episodes, depression or suicide, psychotic episodes and increased aggressiveness and hostility have been experienced.

Dr. Fia Klötz of Uppsala University in Sweden, and colleagues studied the associations between criminality and steroid use in 1,440 Swedish residents tested for the drugs between 1995 and 2001.

They found that those who tested positive for steroid use were about twice as likely to have been convicted of a weapons offence and one and a half times as likely to have been convicted of fraud.

It was revealed that a relationship between anabolic steroids and criminal activities is very much possible and happen. This is possibly because the use of steroids can lead to behavioral changes such as extreme mood swings, impulsiveness, depression, paranoid jealousy, extreme irritability, delusions and impaired judgment.
