Men are drunker than women

Another interesting study that may explain why men are often more afflicted with alcoholism than women, or so they say.

"Despite similar consumptions of alcohol, the men had greater dopamine release than women. This increase was found in the ventral striatum, an area in the brain strongly associated with pleasure, reinforcement and addiction formation."

Also: "another important observation from this study is the decline in alcohol-induced dopamine release with repeated heavy drinking episodes. This may be one of the hallmarks of developing tolerance or transitioning into habit."

It really all has everything to do with dopamine.
