Anabolic steroids and the mind.

Anabolic steroids were first used by weight lifters and others involved in pursuits of strength, but are now taken, often in large doses, by young men interested in enhancing their appearance. The severe psychogenic side effects of these high doses include aggressive and violent behaviour. Problems with drug withdrawal and drug dependence are also common in users of anabolic steroids and these drugs may also provoke psychiatric disorders. I review these complications, as reported in the past decade, and comment on two recent violent murders in Sydney in which anabolic steroid use was implicated.
