Recent research conducted by Spanish researchers in collaboration with Brazilian scientists has shown that the regular use of substances like ayahuasca and cannabis does not negatively affect cognitive functions, which contradicts long-held beliefs. The study, led by José Carlos Bouso and senior author Jordi Riba from the International Center for Education, Research, and Ethnobotanical Service (ICEERS) in Barcelona, emphasizes that personality traits, rather than cognitive abilities, distinguish chronic users of these substances from non-users. This finding is significant as it challenges the stigma often associated with cannabis use, which paints users as forgetful or lacking focus.

The research involved a detailed evaluation of individuals who frequently use ayahuasca and cannabis, comparing them with non-users in various cognitive assessments. While cannabis is often linked to a 'slacker' stereotype, the study highlights that these assumptions are unfounded when looking at real cognitive metrics. Instead, the researchers found that personality factors were more predictive of regular use than any impairment in cognitive capability. The implications of this study are profound, as it provides a scientific basis to advocate for a re-evaluation of the societal perceptions surrounding these substances.

This study arrives at a time when the conversation regarding the legality and acceptance of cannabis and ayahuasca is evolving globally. As people increasingly turn to these substances for therapeutic and personal reasons, it's critical that public narratives are aligned with scientific evidence. This research not only contributes to the growing body of knowledge around the neurocognitive effects of these substances but also serves as a rallying point for advocates arguing for more open-minded approaches to drug use and policy reform.
