Does alcohol increase creativity?

In 2019, a study was published that examined the correlation between US patent applications in different counties around the US during the implementation of  Prohibition. Initially, patent applications dropped dramatically. This is shown in the graph below, where 0 on the X-axis represents the year 1920.

Why did this decline only last for 3 years? The hypothesis is that the correlation between the US going dry and patent applications dropping ended then because of the rise in speakeasies. This led the researchers to a couple of conclusions. First, that alcohol itself might enhance creativity, and second, that having social spaces to interact with others is a key element of creativity.
