There were two main problems that were caused by Prohibition.  These were a breakdown in the respect for the law and the growth in the power of organized crime.

After Prohibition was imposed, many people felt that there was no reason for them to obey the law.  They felt that drinking was an okay thing to do.  In fact, they came to feel that going to speakeasies was a fun and glamorous thing to do.  Everyone knew that alcohol was widely available.  This led to a decrease in respect for the law, which is a bad thing in any democratic society.

At the same time, there was a much more tangible negative impact.  This was the rise of organized crime.  With so many Americans wanting to drink, only criminals could satisfy the demand.  The demand was so huge that the organized crime syndicates made huge amounts of money.  This helped lead to the continuing problem of the presence of organized crime in the United States.

These were the main two problems that were caused by the attempt to ban alcohol.

Describe the consequences of Prohibition.

There were a number of consequences of Prohibition.  These can be separated out by type of consequence.

First, let us look at economic consequences.  Prohibition actually harmed the American economy to some degree.  Many people had thought that Prohibition would simply shift spending from alcohol to more productive things and other types of entertainment would prosper.  Instead, the main economic consequences of Prohibition were negative.  Governments lost huge amounts of revenue that had come from taxing alcohol.  Large numbers of legal jobs in the making, transport, and selling of alcohol were lost.  These consequences were quite serious, particularly in the later years of Prohibition when the Great Depression was in full swing.

Second, let us look at social and political consequences.  Politically, Prohibition reduced people’s respect for the law and the government.  The fact that a constitutional amendment was being so widely ignored made a mockery of the idea of law and order.  The idea that people should obey the law simply became weaker.  Socially, there were two major consequences.  First, people actually people started to drink more.  They also drank more dangerous things and many people died each year from drinking unsafe alcohol.  Second, and most importantly, organized crime became a big business.  Gangsters came to dominate the illegal alcohol industry, thus creating powerful crime organizations that have never fully been eradicated. 

Prohibition, then, had many negative consequences of various sorts.

What were the impacts of Prohibition?

The major impacts of Prohibition were negative.  Prohibition reduced the level of respect for the law in the United States.  It encouraged people to think of breaking the law as something of a lark, something that was fun to do.  Perhaps more importantly, Prohibition led to a huge boom in the amount of organized crime in the United States.  With people still wanting alcohol, illegal organizations quickly formed and grew in order to cater to these demands.  This helped bring such people as Al Capone to prominence and helped give power and wealth to their criminal organizations.
