Recently, healthy individuals have been using psychostimulants for cognitive enhancement purposes. Psychostimulant medications may increase wakefulness, but as a tradeoff, they may constrict cognitive flexibility and reduce creativity in healthy individuals with no psychiatric disorders. In this perspective, the author addresses the ethical and prudential issues that arise from impairing creativity with psychostimulants. As there is a strong relationship between creativity and positive mental health, the author argues that creativity is an important character strength. Hence, reducing it with psychostimulants will impair an intrinsically and instrumentally valuable trait, which will in the long term reduce well-being and negatively impact the positive mental health of the healthy individual and the flourishing of society. The author concludes that using psychostimulants as a form of cognitive enhancement in healthy adults is imprudent and morally suspect for society.PERSPECTIVES is a special feature included in this issue of Journal of Creativity in Mental Health that provides mental health professionals with an opportunity to discuss their positions on a variety of creativity-related topics.In this article, Dr. Mohamed shares his view of the ethical and prudential issues that arise from impairing creativity with psychostimulants.Dr. Ahmed Dahir Mohamed is a chartered psychologist member of the British Psychological Society.
