Now a day, cannabis legalization is a subject of a lot debate, both for recreational and medical use. It is important, before any decision is made, to understand the consequences of its use. Quality information can make all the difference in deciding whether to legalize it or not and in preparing to deal with the adverse effects of its use. Some of the effects of cannabis are better known than others. This review has as main objective to try to understand if there is a relationship between cannabis consumption and the amotivational syndrome, a concept that has not met consensus since its introduction. Although the results were not conclusive, there seems to be a greater probability of the existence of this relationship than the opposite, this in heavy cannabis consumers. In addition, some studies provide an explanation of the biology behind this syndrome associated with cannabis use, explained by a decrease in dopamine reactivity and it levels in the brain in heavy consumers. There also seems to be a greater susceptibility in adolescents. However, more studies and of a better quality are needed to be possible to draw a definitive conclusion.
