“The use of synthetic cannabinoid has been increasing throughout the world and has become a major public health problem.

The present study aims to investigate the attention, memory, visuospatial and executive functions in individuals with synthetic cannabinoid use disorder and compare the results with findings obtained from individuals with cannabis use disorder and healthy volunteers with no substance use.

Impairments in attention, memory, executive and visuospatial functions were identified in individuals with synthetic cannabinoid use disorder and these impairments were found to be significantly greater than in individuals with cannabis use disorder and healthy controls.”
