Creativity enhancement is a perceived increase in one's capability to imagine new ideas, create art, or think about existing concepts in a novel manner.    This effect is particularly useful to artists of any sort as it can help a person overcome creative blocks on existing projects and induce inspiration for entirely new projects. Creativity enhancement can make imaginative activities more enjoyable and effortless in the moment and the inspiration from it can benefit the individual even after the effect has worn off.
A well-known example of psychedelic creativity enhancement comes from the Nobel Prize winning chemist Dr. Kary Mullis, who invented a method for copying DNA segments known as the PCR, and is quoted as saying: "Would I have invented PCR if I hadn't taken LSD? I seriously doubt it. I could sit on a DNA molecule and watch the polymers go by. I learned that partly on psychedelic drugs".  In addition, although dubious, it has been claimed Francis Crick experimented with LSD during the time he helped elucidate the structure of DNA. 
Creativity enhancement is often accompanied by other coinciding effects, such as thought connectivity, motivation enhancement, personal bias suppression, analysis enhancement, and thought acceleration, in a manner that further amplifies a person's creativity. It is most commonly induced under the influence of moderate dosages of psychedelic compounds, such as LSD, psilocybin, and mescaline.    However, it can also occur to a lesser extent under the influence of cannabinoids   , dissociatives  , and stimulants.
