From the CDC:
Studies have shown that, when compared with the general population, gay and bisexual men, lesbian, and transgender individuals are more likely to:
Use alcohol and drugs,
Have higher rates of substance abuse,
Not withhold from alcohol and drug use, and
Continue heavy drinking into later life.http://www.cdc.gov/msmhealth/substance-abuse.htm
That being said...I don't drink any alcohol. I know other gay men that don't drink at all. And I know gay men that do not drink to excess. I don't have any close friends that drink to excess. I did stop dating a guy because he got drunk on a regular basis and he was extremely negative.
