It is a well-known fact that drug use has a direct impact on how the brain works. When someone makes music, there is a large and complex volume of signals and information flowing inside the brain, and if drugs are used, then the person’s ability to process melodic concepts and creative ideas becomes incredibly impaired.
There was a study published on how LSD can impact creativity and the results found that hallucinogenic drugs do in fact impair the brain’s ability to use novel sensory perceptions to create original ideas.
Another study was done to see how marijuana affects creativity. The results of this study showed that the more THC that was ingested, the harder it was to come up with creative ideas.
When an outside chemical is added to the body, natural functions negatively change. It’s especially dangerous when emotional desires for stronger creativity develop into an addiction.
