The purpose of this study was to investigate whether cannabis use can affect cognitive functions. The method that was chosen to answer the purpose of the study was a general literature review. Article search occurred in the databases PsycINFO and PubMed. Nine articles were selected based on the study’s inclusion criteria. These studies was then analysed to see that they matched the criterias that were selected in the study regarding study quality. The results show that cannabis use can affect cognitive functions. Though it is not certainly established that the use of cannabis always leads to a negative impact on cognitive functions, two of the nine included studies showed that this was not the case. It was possible to see that cannabis use can lead to a change in activity in regions of the brain that are associated with cognitive function. Seven out of nine studies showed that cannabis use leads to a negative impact on cognitive functions, particularly in the form of memory impairment.
