Steroids change the central nervous system sensitivity to cannabis
Some steroid users may use cannabis to improve their sleep and decrease stress. There are less studies about the concurrent use of cannabis and anabolic steroids than about the concurrent use of steroids and stimulating drugs.
Anabolic steroids also lessen the pleasure of cannabis use. Nandrolone lessens the rewarding effect of the active substance of cannabis, THC, in laboratory animals, but it simultaneously increases the withdrawal symptoms that appear after the use . Therefore, steroids possibly change the central nervous system sensitivity to cannabis.
Using alcohol and steroids concurrently adds aggressiveness
In laboratory animals, nandrolone increases the alcohol use for a long time after quitting the use of steroids. Together with abundant alcohol use, anabolic steroids further increase behavior problems caused by alcohol, such as losing control of things and self-control .
This may be a consequence of the effects of anabolic steroids on the functioning of the brain serotonin tractus . For example, concurrent use of nandrolone and alcohol lessens fear and timidity and significantly adds aggressive behavior compared to use of only alcohol . Thus, the use of anabolic steroids is sometimes connected to hate crimes, such as violent crimes .
These and several other research results support the assumption that anabolic steroids effect on an individual’s behavior and alter the effects of other toxicants by changing the biochemical functions of the central nervous system.
