Effect of Prohibition
People couldnt resist alcohol still so many Speakeasies were set up. Gangsters and crimes profited by selling the more expensive drinks when alcohol became illegal. Actually, there were more speakeasies during Prohibition than the legal saloons before this law set up!
Some people made their own stills, Bootleg, and also Moonshine which was harmful to drink. If the police ever caught one, they often got bribed and some pretended that they didnt notice in case a group of gangster or Mafia, who armed with guns ran the illegal saloons.
In fact, Prohibition decreased the consumption of alcohol. Prohibition reduced the annual per capita consumption from 9.8litres (2.6gallons) of alcohol to 3.7litres (0.97gallons) in the end. Prohibition also increased the crime rate during 1920s.
